Becoming Catholic Study Bank: Church Unity Commanded in the New Testament

Making Wisdom Popular

The “Becoming Catholic” blog series is a multi-part, multi-year, bite-size, fact-focused attempt at describing the journey of a lifelong protestant to the Catholic Church.  You can read all the individual articles here.

This Study Bank on the New Testament commands regarding Church Unity is part of the Becoming Catholic series. When preparing articles, I typically engage in a substantial amount of research, and often organize it in separate documents I then use as a reference when writing the article. Sometimes these are Scripture word studies, other times they are compilations of verses or patristic and other quotes on particular subjects, etc. I have found that organizing the data often leads to a better understanding of the topic at hand.

A Study Bank, therefore, is in no way an article, or presenting an argument. It is simply a compilation of data on a particular topic.

In this Study Bank, I cover the New Testament commands regarding Church Unity.

In each citation, in order to provide a reasonable amount of context in a way that does not depend on my own subjective judgment, I include the full paragraph in which the verse is contained—no matter how long, or short.

There are at least 23 examples of the unity of the Church being explicitly commanded or described in individual verses, or even whole sections of the New Testament.

QUOTES OF CITATIONS

Matthew

(Matt. 28:19-20)

19 Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 teaching them to observe all that I have commanded you; and lo, I am with you always, to the close of the age.”

(Matt. 12:25, 30)

25 Knowing their thoughts, he said to them, “Every kingdom divided against itself is laid waste, and no city or house divided against itself will stand30 He who is not with me is against me, and he who does not gather with me scatters

John

(John 10:16)

16 And I have other sheep, that are not of this fold; I must bring them also, and they will heed my voice. So there shall be one flock, one shepherd.

(John 13:34-35)

34 A new commandment I give to you, that you love one another; even as I have loved you, that you also love one another. 35 By this all men will know that you are my disciples, if you have love for one another.

(John 17:1-26)

When Jesus had spoken these words, he lifted up his eyes to heaven and said, “Father, the hour has come; glorify thy Son that the Son may glorify thee, 2 since thou hast given him power over all flesh, to give eternal life to all whom thou hast given him. 3 And this is eternal life, that they know thee the only true God, and Jesus Christ whom thou hast sent. 4 I glorified thee on earth, having accomplished the work which thou gavest me to do; 5 and now, Father, glorify thou me in thy own presence with the glory which I had with thee before the world was made.

6 “I have manifested thy name to the men whom thou gavest me out of the world; thine they were, and thou gavest them to me, and they have kept thy word. 7 Now they know that everything that thou hast given me is from thee; 8 for I have given them the words which thou gavest me, and they have received them and know in truth that I came from thee; and they have believed that thou didst send me. 9 I am praying for them; I am not praying for the world but for those whom thou hast given me, for they are thine; 10 all mine are thine, and thine are mine, and I am glorified in them. 11 And now I am no more in the world, but they are in the world, and I am coming to thee. Holy Father, keep them in thy name, which thou hast given me, that they may be one, even as we are one. 12 While I was with them, I kept them in thy name, which thou hast given me; I have guarded them, and none of them is lost but the son of perdition, that the scripture might be fulfilled. 13 But now I am coming to thee; and these things I speak in the world, that they may have my joy fulfilled in themselves. 14 I have given them thy word; and the world has hated them because they are not of the world, even as I am not of the world. 15 I do not pray that thou shouldst take them out of the world, but that thou shouldst keep them from the evil one. 16 They are not of the world, even as I am not of the world. 17 Sanctify them in the truth; thy word is truth. 18 As thou didst send me into the world, so I have sent them into the world. 19 And for their sake I consecrate myself, that they also may be consecrated in truth.

20 “I do not pray for these only, but also for those who believe in me through their word, 21 that they may all be one; even as thou, Father, art in me, and I in thee, that they also may be in us, so that the world may believe that thou hast sent me. 22 The glory which thou hast given me I have given to them, that they may be one even as we are one, 23 I in them and thou in me, that they may become perfectly one, so that the world may know that thou hast sent me and hast loved them even as thou hast loved me. 24 Father, I desire that they also, whom thou hast given me, may be with me where I am, to behold my glory which thou hast given me in thy love for me before the foundation of the world. 25 O righteous Father, the world has not known thee, but I have known thee; and these know that thou hast sent me. 26 I made known to them thy name, and I will make it known, that the love with which thou hast loved me may be in them, and I in them.

Acts

(Acts 4:32)

32 Now the company of those who believed were of one heart and soul, and no one said that any of the things which he possessed was his own, but they had everything in common.

Romans

(Rom. 12:4-5)

4 For as in one body we have many members, and all the members do not have the same function, 5 so we, though many, are one body in Christ, and individually members one of another.

(Rom. 12:16)

16 Live in harmony with one another; do not be haughty, but associate with the lowly; never be conceited.

(Rom. 14:19)

19 Let us then pursue what makes for peace and for mutual upbuilding.

1 Corinthians

(1 Cor. 1:10-15)

10 I appeal to you, brethren, by the name of our Lord Jesus Christ, that all of you agree and that there be no dissensions among you, but that you be united in the same mind and the same judgment. 11 For it has been reported to me by Chloe’s people that there is quarreling among you, my brethren. 12 What I mean is that each one of you says, “I belong to Paul,” or “I belong to Apollos,” or “I belong to Cephas,” or “I belong to Christ.” 13 Is Christ divided? Was Paul crucified for you? Or were you baptized in the name of Paul? 14 I am thankful that I baptized none of you except Crispus and Gaius; 15 lest anyone should say that you were baptized in my name.

(1 Cor. 12:12-26)

12 For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ. 13 For by one Spirit we were all baptized into one body—Jews or Greeks, slaves or free—and all were made to drink of one Spirit.

14 For the body does not consist of one member but of many. 15 If the foot should say, “Because I am not a hand, I do not belong to the body,” that would not make it any less a part of the body. 16 And if the ear should say, “Because I am not an eye, I do not belong to the body,” that would not make it any less a part of the body. 17 If the whole body were an eye, where would be the hearing? If the whole body were an ear, where would be the sense of smell? 18 But as it is, God arranged the organs in the body, each one of them, as he chose. 19 If all were a single organ, where would the body be? 20 As it is, there are many parts, yet one body. 21 The eye cannot say to the hand, “I have no need of you,” nor again the head to the feet, “I have no need of you.” 22 On the contrary, the parts of the body which seem to be weaker are indispensable, 23 and those parts of the body which we think less honorable we invest with the greater honor, and our unpresentable parts are treated with greater modesty, 24 which our more presentable parts do not require. But God has so adjusted the body, giving the greater honor to the inferior part, 25 that there may be no discord in the body, but that the members may have the same care for one another. 26 If one member suffers, all suffer together; if one member is honored, all rejoice together.

2 Corinthians

(2 Cor. 13:11)

11 Finally, brethren, farewell. Mend your ways, heed my appeal, agree with one another, live in peace, and the God of love and peace will be with you.

Galatians

(Gal. 3:28)

28 There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus.

(Gal. 5:19-21)

19 Now the works of the flesh are plain: immorality, impurity, licentiousness, 20 idolatry, sorcery, enmity, strife, jealousy, anger, selfishness, dissension, party spirit [factions, heresies], 21 envy, drunkenness, carousing, and the like. I warn you, as I warned you before, that those who do such things shall not inherit the kingdom of God.

The same word translated as “party spirit” in Gal. 5:20 is used in 1 Cor. 11:19:

18 For, in the first place, when you assemble as a church, I hear that there are divisions among you; and I partly believe it, 19 for there must be factions among you in order that those who are genuine among you may be recognized.

Ephesians

(Eph. 1:9-10)

9 For he has made known to us in all wisdom and insight the mystery of his will, according to his purpose which he set forth in Christ 10 as a plan for the fulness of time, to unite all things in him, things in heaven and things on earth.

(Eph. 4:1-6, 11-13)

I therefore, a prisoner for the Lord, beg you to lead a life worthy of the calling to which you have been called, 2 with all lowliness and meekness, with patience, forbearing one another in love, 3 eager to maintain the unity of the Spirit in the bond of peace. 4 There is one body and one Spirit, just as you were called to the one hope that belongs to your call, 5 one Lord, one faith, one baptism, 6 one God and Father of us all, who is above all and through all and in all…

11 And his gifts were that some should be apostles, some prophets, some evangelists, some pastors and teachers, 12 for the equipment of the saints, for the work of ministry, for building up the body of Christ, 13 until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ

Philippians

(Phil. 2:1-2)

So if there is any encouragement in Christ, any incentive of love, any participation in the Spirit, any affection and sympathy, 2 complete my joy by being of the same mind, having the same love, being in full accord and of one mind.

Colossians

(Col. 3:12-15)

12 Put on then, as God’s chosen ones, holy and beloved, compassion, kindness, lowliness, meekness, and patience, 13 forbearing one another and, if one has a complaint against another, forgiving each other; as the Lord has forgiven you, so you also must forgive. 14 And above all these put on love, which binds everything together in perfect harmony. 15 And let the peace of Christ rule in your hearts, to which indeed you were called in the one body.

1 Timothy

(1 Tim. 3:14-15)

14 I hope to come to you soon, but I am writing these instructions to you so that, 15 if I am delayed, you may know how one ought to behave in the household of God, which is the church of the living God, the pillar and bulwark of the truth.

Titus

(Tit. 3:10-11)

10 As for a man who is factious, after admonishing him once or twice, have nothing more to do with him, 11 knowing that such a person is perverted and sinful; he is self-condemned.

Hebrews

(Heb. 12:12-17)

12 Therefore lift your drooping hands and strengthen your weak knees, 13 and make straight paths for your feet, so that what is lame may not be put out of joint but rather be healed. 14 Strive for peace with all men, and for the holiness without which no one will see the Lord. 15 See to it that no one fail to obtain the grace of God; that no “root of bitterness” spring up and cause trouble, and by it the many become defiled; 16 that no one be immoral or irreligious like Esau, who sold his birthright for a single meal. 17 For you know that afterward, when he desired to inherit the blessing, he was rejected, for he found no chance to repent, though he sought it with tears.

1 Peter

(1 Pet. 3:8)

8 Finally, all of you, have unity of spirit, sympathy, love of the brethren, a tender heart and a humble mind.

Jude

(Jude 1:8-13)

8 Yet in like manner these men in their dreamings defile the flesh, reject authority, and revile the glorious ones. 9 But when the archangel Michael, contending with the devil, disputed about the body of Moses, he did not presume to pronounce a reviling judgment upon him, but said, “The Lord rebuke you.” 10 But these men revile whatever they do not understand, and by those things that they know by instinct as irrational animals do, they are destroyed. 11 Woe to them! For they walk in the way of Cain, and abandon themselves for the sake of gain to Balaam’s error, and perish in Korah’s rebellion. 12 These are blemishes on your love feasts, as they boldly carouse together, looking after themselves; waterless clouds, carried along by winds; fruitless trees in late autumn, twice dead, uprooted; 13 wild waves of the sea, casting up the foam of their own shame; wandering stars for whom the nether gloom of darkness has been reserved for ever.
