Romans 12:5

In Christ. — Christ is the unifying principle in the Church, just as the personality or will is the unifying principle in man.

Every one. — A somewhat peculiar phrase in the Greek, not found in this form in classical writers, meaning “as individuals.”

Members one of another. — Strictly speaking, the members are called members in their relation to the body, and not in their relation to each other. We should say, rather, “fellow-members with one another.”
