/summa/TP/TPII/TP_Q30:
We now have to consider the Blessed Virgin's Annunciation, concerning which there are four points of inquiry:
(1) Whether it was befitting that announcement should be made to her of that which was to be begotten of her?
(2) By whom should this announcement be made?
(3) In what manner should this announcement be made?
(4) Of the order observed in the Annunciation.
