[¶0] OF CHRIST'S UNITY OF BEING (TWO ARTICLES)

[¶1] 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.

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

[¶3] Under the first head there are two points of inquiry:

[¶4] (1) Whether Christ is one or two?

[¶5] (2) Whether there is only one being in Christ?
