The unity among Jesus' body, for which he prayed in the garden, by which the world will know that the Father has sent the Son, is founded upon the simplicity that is in Christ Jesus as found in 1 Corinthians 15:1-4.
1 Cor 15:1-4
1 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
2 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
4 And that he was buried, and that he rose again the third day according to the scriptures: KJV
Let us beware lest we are beguiled away from the simplicity of Christ and receive each other upon doubtful disputations. Doubtful disputations create divisions.
Let us receive each other as little children. Let the young men and the fathers care for the little children.
1 John 2:12
I write unto you, little children, because your sins are forgiven you for his name's sake. KJV
1 John 2:13
I write unto you, little children, because ye have known the Father. KJV
