OF CHRIST'S UNITY OF BEING (TWO ARTICLES)

We must now consider what pertains to Christ's unity in common. For, in their proper place, we must consider what pertains to unity and plurality in detail: thus we concluded (Q[9]) that there is not only one knowledge in Christ, and it will be concluded hereafter (Q[35], A[2]) that there is not only one nativity in Christ.

Hence we must consider Christ's unity (1) of being; (2) of will; (3) of operation.

Under the first head there are two points of inquiry:

(1) Whether Christ is one or two?

(2) Whether there is only one being in Christ?
