Church correlation operates by revelation from the Lord to His prophets and establishes, among other things, proper relationships among the organizations of the Church.
Doctrine and Covenants 84:109–110
109 Therefore, let every man stand in his own office, and labor in his own calling; and let not the head say unto the feet it hath no need of the feet; for without the feet how shall the body be able to stand?
110 Also the body hath need of every member, that all may be edified together, that the system may be kept perfect.
President Harold B. Lee said:
“In the great, modern-day revelation on Church government, the Lord concludes with this statement:
“‘Behold, this is the way that mine apostles, in ancient days, built up my church unto me.
“‘Therefore, let every man stand in his own office, and labor in his own calling; and let not the head say unto the feet it hath no need of the feet; for without the feet how shall the body be able to stand?
“‘Also the body hath need of every member, that all may be edified together, that the system may be kept perfect’ (D&C 84:108–10).
“Obviously, as you think about those scriptures, they were given to impress the need for the constant and continued consultations and correlations of the various subdivisions, the priesthood quorums and the auxiliaries and all other units within the kingdom of God for at least four reasons:
“First, that each organization was to have its specific function, and it was not to usurp the field of the other, which would be like the eye saying to the hand, ‘I have no need of thee.’
“Second, that each subdivision is of equal importance in the work of salvation, just as each part of the physical body is essential to a complete human being.
“Third, that all may be edified or educated together; and
“Fourth, that the system may be kept perfect, or in other words, that within the framework of the Lord’s plan of organization for the salvation of His children, the Church will perform as a perfectly organized human body, with every member functioning as it was intended.”
