Why is unity important?

The psalmist declared: “Behold, how good and how pleasant it is for brethren to dwell together in unity!” (Psalm 133:1).

Shortly before His crucifixion, Christ, in His prayer to His Father, prayed, “Neither pray I for these alone, but for them also which shall believe on me through their word; That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me. And the glory which thou gavest me I have given them; that they may be one, even as we are one” (John 17:20–22). We can have that glory when we are united.

Yet, while seeking to cooperate with Christ in fostering the circumstances required in fulfilling the answer to this prayer, we cannot surrender the truth.

“We cannot surrender the truth in order to accomplish this union; for the very means by which it is to be gained is sanctification through the truth. Human wisdom would change all this, thinking this basis of union too narrow. Men would effect a union through conformity to popular opinions, through a compromise with the world. But truth is God's basis for the unity of His people.”3

“Our churches are becoming enfeebled by receiving for doctrines the commandments of men. Many are received into the church who are not converted. Men, women, and children are allowed to take part in the solemn rite of baptism without being fully instructed in regard to the meaning of His ordinance. . . . Christ calls for unity. But He does not call for us to unify on wrong practices. The God of heaven draws a sharp contrast between pure, elevating, ennobling truth and false, misleading doctrines. He calls sin and impenitence by the right name.”4

As apostasy gradually crept into the early Christian church, “after a long and severe conflict, the faithful few decided to dissolve all union with the apostate church if she still refused to free herself from falsehood and idolatry. They saw that separation was an absolute necessity if they would obey the word of God. They dared not tolerate errors fatal to their own souls, and set an example which would imperil the faith of their children and children's children. To secure peace and unity they were ready to make any concession consistent with fidelity to God; but they felt that even peace would be too dearly purchased at the sacrifice of principle. . . .

“There is an alarming indifference in regard to the doctrines which are the pillars of the Christian faith. The opinion is gaining ground, that, after all, these are not of vital importance. This degeneracy is strengthening the hands of the agents of Satan, so that false theories and fatal delusions which the faithful in ages past imperiled their lives to resist and expose, are now regarded with favor by thousands who claim to be followers of Christ.”5

Whatever or whomever we associate with makes an impact on us. The stronger and more frequent the association, the greater the influence it will have.

“We cannot willingly associate with those who are trampling upon the law of God, and preserve our faith pure and untarnished. We shall catch the spirit, and unless we separate from them, we shall be bound up with them at last, to share their doom.

“It was by associating with idolaters and joining in their festivities that the Hebrews were led to transgress God's law and bring His judgments upon the nation. So now it is by leading the followers of Christ to associate with the ungodly and unite in their amusements that Satan is most successful in alluring them into sin. 'Come out from among them, and be ye separate, saith the Lord, and touch not the unclean.' God requires of His people now as great a distinction from the world, in customs, habits, and principles, as He required of Israel anciently.”6

“We cannot be too decided in shunning the company of those who exert an influence to draw us away from God. While we pray, 'Lead us not into temptation,' we are to shun temptation, so far as possible.”7

“The different parties of professed Advent believers have each a little truth, but God has given all these truths to His children who are being prepared for the day of God. He has also given them truths that none of these parties know, neither will they understand. Things which are sealed up to them, the Lord has opened to those who will see and are ready to understand. If God has any new light to communicate, He will let His chosen and beloved understand it, without their going to have their minds enlightened by hearing those who are in darkness and error.

“I was shown the necessity of those who believe that we are having the last message of mercy, being separate from those who are daily imbibing new errors. I saw that neither young nor old should attend their meetings; for it is wrong to thus encourage them while they teach error that is a deadly poison to the soul and teach for doctrines the commandments of men. The influence of such gatherings is not good. If God has delivered us from such darkness and error, we should stand fast in the liberty wherewith He has set us free and rejoice in the truth. God is displeased with us when we go to listen to error, without being obliged to go; for unless He sends us to those meetings where error is forced home to the people by the power of the will, He will not keep us. The angels cease their watchful care over us, and we are left to the buffetings of the enemy, to be darkened and weakened by him and the power of his evil angels; and the light around us becomes contaminated with the darkness.

“I saw that we have no time to throw away in listening to fables. Our minds should not be thus diverted, but should be occupied with the present truth, and seeking wisdom that we may obtain a more thorough knowledge of our position, that with meekness we may be able to give a reason of our hope from the Scriptures.”8

Does this mean no association with the world at all?

“The question may be asked, Are we to have no union whatever with the world? The word of the Lord is to be our guide. Any connection with infidels and unbelievers which would identify us with them is forbidden by the word. We are to come out from them and be separate. In no case are we to link ourselves with them in their plans or work. But we are not to live reclusive lives. We are to do worldlings all the good we possibly can. Christ has given us an example of this. When invited to eat with publicans and sinners, He did not refuse; for in no other way than by mingling with them could He reach this class. But on every occasion He gave them talents of words and influence. He opened up themes of conversation which brought things of eternal interest to their minds.”9

“The word of God is a book of truth.”10

Through the proclamation of the truth, we are drawn to the church. “How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher? And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things! But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report? So then faith cometh by hearing, and hearing by the word of God” (Romans 10:14–17).

Because of this important aspect of faith, God is seeking to draw everyone to hear the truth, by His preachers and teachers in His church. Jesus reminds us that “other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd” (John 10:16). “To you, My disciples, I commit this message of mercy. It is to be given to both Jews and Gentiles—to Israel, first, and then to all nations, tongues, and peoples. All who believe are to be gathered into one church.”11

1. Maintain the truth

2. Teach the truth

What happens if a church does not maintain the truth? It will teach error.

What happens if a church does not teach the truth? It will lower the standards of God's Word.

Therefore, the apostle admonishes: “Take heed unto thyself, and unto the doctrine; continue in them: for in doing this thou shalt both save thyself, and them that hear thee” (1 Timothy 4:16).

“Strength comes by exercise. All who put to use the ability which God has given them will have increased ability to devote to His service. . . . The Christian who will not exercise his God-given powers not only fails to grow up into Christ, but he loses the strength which he already has; he becomes a spiritual paralytic.”12

“The Lord had made the Jews the depositaries of sacred truth. He had appointed them stewards of His grace. He had given them every spiritual and temporal advantage, and He called upon them to impart these blessings. . . . Filled with pride, they regarded themselves as the chosen and favored people of God; yet they did not serve or worship God. They put their dependence in the fact that they were children of Abraham. 'We be Abraham's seed,' they said proudly. (John 8:33.) When the crisis came, it was revealed that they had divorced themselves from God, and had placed their trust in Abraham, as if he were God.”13

After a while they perverted the truth.

“The teachers of the Jewish nation professed to educate the youth to understand the purity and excellence of the laws of that kingdom which is to stand forever and ever, but they perverted truth and purity. . . . The greater their perversion of figures and symbols, the more confused their minds became.”14

“The Sanhedrin had rejected Christ's message and was bent upon His death; therefore Jesus departed from Jerusalem, from the priests, the temple, the religious leaders, the people who had been instructed in the law, and turned to another class to proclaim His message, and to gather out those who should carry the gospel to all nations.”15

Why this class? “To gather out those who should carry the gospel to all nations.” They would do the job correctly by teaching the pure truth.

The word “church” (ekklesia) refers to a calling out. The very concept indicates a need for separation. The first step that Jesus took in making the necessary separation was to ordain the twelve disciples for their mission (Mark 3:13, 14).

The Lord has given some guidelines about how the church is then to guard the truth within its borders. He explains the process: “If thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother. But if he will not hear thee, then take with thee one or two more, that in the mouth of two or three witnesses every word may be established. And if he shall neglect to hear them, tell it unto the church: but if he neglect to hear the church, let him be unto thee as an heathen man and a publican. Verily I say unto you, Whatsoever ye shall bind on earth shall be bound in heaven: and whatsoever ye shall loose on earth shall be loosed in heaven” (Matthew 18:15–18).

“On the church has been conferred the power to act in Christ's stead. It is God's instrumentality for the preservation of order and discipline among His people. To it the Lord has delegated the power to settle all questions respecting its prosperity, purity, and order. Upon it rests the responsibility of excluding from its fellowship those who are unworthy, who by their unchristlike conduct would bring dishonor on the truth. Whatever the church does that is in accordance with the directions given in God's word, will be ratified in heaven.”16

The Lord explains further: “And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven” (Matthew 16:19).

“Peter had expressed the truth which is the foundation of the church's faith, and Jesus now honored him as the representative of the whole body of believers. He said, 'I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.' 'The keys of the kingdom of heaven' are the words of Christ. All the words of Holy Scripture are His, and are here included. These words have power to open and to shut heaven. They declare the conditions upon which men are received or rejected. Thus the work of those who preach God's word is a savor of life unto life or of death unto death. Theirs is a mission weighted with eternal results.”17

“And when [Jesus] had said this, he breathed on them, and saith unto them, Receive ye the Holy Ghost: Whose soever sins ye remit, they are remitted unto them; and whose soever sins ye retain, they are retained” (John 20:22, 23).

“On the church in its organized capacity He places a responsibility for the individual members. Toward those who fall into sin, the church has a duty, to warn, to instruct, and if possible to restore. 'Reprove, rebuke, exhort,' the Lord says, 'with all long-suffering and doctrine.' 2 Timothy 4:2. Deal faithfully with wrongdoing. Warn every soul that is in danger. Leave none to deceive themselves. Call sin by its right name. Declare what God has said in regard to lying, Sabbathbreaking, stealing, idolatry, and every other evil. 'They which do such things shall not inherit the kingdom of God.' Galatians 5:21. If they persist in sin, the judgment you have declared from God's word is pronounced upon them in heaven. In choosing to sin, they disown Christ; the church must show that she does not sanction their deeds, or she herself dishonors her Lord. She must say about sin what God says about it. She must deal with it as God directs, and her action is ratified in heaven. He who despises the authority of the church despises the authority of Christ Himself.”18

In the famous Great Commission Christ gave in Matthew 28:18–20 and Mark 16:15–20, He bids us teach pure truth as He taught it, through the power provided through His Holy Spirit.

“The work of God in the earth presents, from age to age, a striking similarity in every great reformation or religious movement. The principles of God's dealing with men are ever the same. The important movements of the present have their parallel in those of the past, and the experience of the church in former ages has lessons of great value for our own time.”19

1. Genesis 12:1 shows the separation of Abraham from the idolatrous practices of his surroundings in order to establish the Hebrew nation. “By faith Abraham, when he was called to go out into a place which he should after receive for an inheritance, obeyed; and he went out, not knowing whither he went” (Hebrews 11:8).

2. Centuries later, there was eventual need of separation in the early church from that nation which had been called, but had since apostatized. “The Jewish nation was a fruitless branch, and was therefore to be separated from the living vine, which was Christ Jesus. The Gentiles were to be engrafted upon the stalk, to become a living branch, partaker of the life that nourished the true vine.”20

They did not even realize they had been rejected. “When God's presence was finally withdrawn from the Jewish nation, priests and people knew it not. Though under the control of Satan, and swayed by the most horrible and malignant passions, they still regarded themselves as the chosen of God. The ministration in the temple continued; sacrifices were offered upon its polluted altars, and daily the divine blessing was invoked upon a people guilty of the blood of God's dear Son and seeking to slay His ministers and apostles.”21

3. Later within Christendom: “After a long and severe conflict, the faithful few decided to dissolve all union with the apostate church if she still refused to free herself from falsehood and idolatry. They saw that separation was an absolute necessity if they would obey the word of God. They dared not tolerate errors fatal to their own souls, and set an example which would imperil the faith of their children and children's children. To secure peace and unity they were ready to make any concession consistent with fidelity to God; but they felt that even peace would be too dearly purchased at the sacrifice of principle.”22

“Romanists have persisted in bringing against Protestants the charge of heresy and willful separation from the true church. But these accusations apply rather to themselves. They are the ones who laid down the banner of Christ and departed from 'the faith which was once delivered unto the saints.' ”23

4. Under the preaching of the three angels' messages: “As ministers and religious leaders decided against the advent doctrine and desired to suppress all agitation of the subject, they not only opposed it from the pulpit, but denied their members the privilege of attending preaching upon the second advent, or even of speaking of their hope in the social meetings of the church. Thus the believers found themselves in a position of great trial and perplexity. They loved their churches and were loath to separate from them; but as they saw the testimony of God's word suppressed and their right to investigate the prophecies denied they felt that loyalty to God forbade them to submit. Those who sought to shut out the testimony of God's word they could not regard as constituting the church of Christ, 'the pillar and ground of the truth.' Hence they felt themselves justified in separating from their former connection.”24

“As the light and life of men was rejected by the ecclesiastical authorities in the days of Christ, so it has been rejected in every succeeding generation. Again and again the history of Christ's withdrawal from Judea has been repeated. When the Reformers preached the word of God, they had no thought of separating themselves from the established church; but the religious leaders would not tolerate the light, and those that bore it were forced to seek another class, who were longing for the truth. In our day few of the professed followers of the Reformers are actuated by their spirit. Few are listening for the voice of God, and ready to accept truth in whatever guise it may be presented. Often those who follow in the steps of the Reformers are forced to turn away from the churches they love, in order to declare the plain teaching of the word of God. And many times those who are seeking for light are by the same teaching obliged to leave the church of their fathers, that they may render obedience.”25

“The Lord Jesus will always have a chosen people to serve Him. When the Jewish people rejected Christ, the Prince of life, He took from them the kingdom of God and gave it unto the Gentiles. God will continue to work on this principle with every branch of His work. When a church proves unfaithful to the word of the Lord, whatever their position may be, however high and sacred their calling, the Lord can no longer work with them. Others are then chosen to bear important responsibilities. But, if these in turn do not purify their lives from every wrong action, if they do not establish pure and holy principles in all their borders, then the Lord will grievously afflict and humble them and, unless they repent, will remove them from their place and make them a reproach.”26

“When the irrevocable decision of the sanctuary has been pronounced and the destiny of the world has been forever fixed, the inhabitants of the earth will know it not. The forms of religion will be continued by a people from whom the Spirit of God has been finally withdrawn; and the satanic zeal with which the prince of evil will inspire them for the accomplishment of his malignant designs, will bear the semblance of zeal for God.”27

In the meantime, the church that speaks the truth has some disagreeable responsibilities.

“God has selected a people in these last days whom He has made the depositaries of His law, and this people will ever have disagreeable tasks to perform. . . . It will require much diligence and a continual struggle to keep evil out of our churches. There must be rigid, impartial discipline exercised; for some who have a semblance of religion will seek to undermine the faith of others and will privily work to exalt themselves.”28

Jesus says, “ 'I know thy works, and thy labor, and thy patience, and how thou canst not bear them which are evil: and thou hast tried them which say they are apostles, and are not, and hast found them liars.' This labor of purifying the church is a painful work, but one that must not be neglected, if the church would have the commendation of God. But repent, because thou hast left thy first love. Here is plainly presented before us our work as members of the church of Christ. If we are faithless, we shall lose the crown of life and another will take it; for in the dropping out of the faithless the places are supplied by the faithful. If we refuse to let our light shine for the Master, if we do not do the works of God, others will do that very work which we might have done and could have done, but refused to do. When we cease to fulfill our mission, when the candlestick refuses to reflect light, and the great truths committed to us individually in trust for the world, are not given to them, then the candlestick will be removed. 'I will come unto thee quickly, and will remove thy candlestick out of his place.' Another will be placed in his stead and will shine. Let prayer be ascending now without delay to Him who walketh in the midst of the golden candlesticks. Take not thy Holy Spirit from us. 'Purge me with hyssop, and I shall be clean: wash me, and I shall be whiter than snow. . . . Create in me a clean heart, O God; and renew a right spirit within me. Cast me not away from thy presence; and take not thy Holy Spirit from me. Restore unto me the joy of thy salvation; and uphold me with thy free Spirit. Then will I teach transgressors thy ways: and sinners shall be converted unto thee.' ”29

May the Lord strengthen us by faith to honor Him in this essential duty!
