Concerning the first, three things occur to be considered: first, the fitness of the Incarnation; secondly, the mode of union of the Word Incarnate; thirdly, what follows this union.

Under the first head there are six points of inquiry:

(1) Whether it is fitting for God to become incarnate?

(2) Whether it was necessary for the restoration of the human race?

(3) Whether if there had been no sin God would have become incarnate?

(4) Whether He became incarnate to take away original sin rather than actual?

(5) Whether it was fitting for God to become incarnate from the beginning of the world?

(6) Whether His Incarnation ought to have been deferred to the end of the world?
