CHAPTER VI: QUESTION 4: THE MODE OF THE UNION ON THE PART OF THE HUMAN NATURE ASSUMED


PROLOGUE

We must now discuss the mode of the union not on the part of the person assuming, but on the part of what was assumed; and here two things must be considered.

1) What the Word assumed:

a) The human nature itself (q. 4).

b) Of the parts of the human nature, which refutes Docetism and Apollinarianism (q. 5).

c) Of the order of this assumption, for example, whether the soul was assumed before the flesh (q. 6).

2) What things were co-assumed:

a) of perfections, where the habitual grace of Christ, His knowledge and power are discussed;

b) of defects, or of those defects which Christ voluntarily accepted for our satisfaction, such as passibility of the body, death, in which Christ's impeccability is discussed, as also His propassions. (q. 7-15)

Thus the treatise on the hypostatic union is complete, since we find discussed: (a) the union itself (q. 2); (b) the person assuming (q. 3); (c) the nature assumed, both as to its parts and those things co-assumed (q. 4-15). Afterward there will be a discussion of the consequences of the union, in themselves and in their relations both to the Father and to us.

The fourth question contains six articles, treating of the human nature in itself, both in its relation to human personality, which Christ did not have, and in its relation to individuals of the human nature.
