Whether it was necessary to announce to the Blessed Virgin that which was to be done in her?

❌ Objection 1 : It would seem that it was unnecessary to announce to the Blessed Virgin that which was to be done in her. For there seems to have been no need of the Annunciation except for the purpose of receiving the Virgin's consent. But her consent seems to have been unnecessary: because the Virginal Conception was foretold by a prophecy of "predestination," which is "fulfilled without our consent," as a gloss says on Mt. 1:22. There was no need, therefore, for this Annunciation.

❌ Objection 2 : Further, the Blessed Virgin believed in the Incarnation, for to disbelieve therein excludes man from the way of salvation; because, as the Apostle says (Rm. 3:22): "The justice of God (is) by faith of Jesus Christ." But one needs no further instruction concerning what one believes without doubt. Therefore the Blessed Virgin had no need for the Incarnation of her Son to be announced to her.

❌ Objection 3 : Further, just as the Blessed Virgin conceived Christ in her body, so every pious soul conceives Him spiritually. Thus the Apostle says (Gal. 4:19): "My little children, of whom I am in labor again, until Christ be formed in you." But to those who conceive Him spiritually no announcement is made of this conception. Therefore neither should it have been announced to the Blessed Virgin that she was to conceive the Son of God in her womb.
