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:

A[1] Whether it is fitting for God to become incarnate?

A[2] Whether it was necessary for the restoration of the human race?

A[3] Whether if there had been no sin God would have become incarnate?

A[4] Whether He became incarnate to take away original sin rather than actual?

A[5] Whether it was fitting for God to become incarnate from the beginning of the world?

A[6] Whether His Incarnation ought to have been deferred to the end of the world?
