Scripture portrays great richness and variety in the use of the term. There is the unity of the [[believer]] with his [[Lord]], and there is the union manifested in the [[body of Christ]], the [[Church]], which rests eventually on a deeper unity of believers in “one Lord, one faith, one baptism.” Unity with Christ is illustrated in many ways: that of [[husband and wife]], or the stones and the building. The classic analogy is the [[vine and the branches]] (cf. John 15 passim). Apart from such unity the follower of Christ can “do nothing.” The unity is his life and the ground of his action.
