Whether Christ's birth should have been made known to some?

Objections

Objection 1 : It would seem that Christ's birth should not have been made known to anyone. For, as stated above (Article [1], ad 3), it befitted the salvation of mankind that Christ's first coming should be hidden. But Christ came to save all; according to 1 Tim. 4:10: "Who is the Saviour of all men, especially of the faithful." Therefore Christ's birth should not have been made known to anyone.
Objection 2 : Further, before Christ was born, His future birth was made known to the Blessed Virgin and Joseph. Therefore it was not necessary that it should be made known to others after His birth.
Objection 3 : Further, no wise man makes known that from which arise disturbance and harm to others. But, when Christ's birth was made known, disturbance arose: for it is written (Mt. 2:3) that "King Herod, hearing" of Christ's birth, "was troubled, and all Jerusalem with him." Moreover, this brought harm to others; because it was the occasion of Herod's killing "all the male children that were in Bethlehem . . . from two years old and under." Therefore it seems unfitting for Christ's birth to have been made known to anyone.
