Catena Aurea · Matthäusevangelium 2
Now when Jesus was born in Bethlehem of Judæa in the days of Herod the king, behold, there came wise men from the east to Jerusalem, Saying, Where is He that is born King of the Jews? for we have seen His star in the east, and are come to worship Him.
(Hom. in Ev. Lib. i. Hom. 10.) To the Jews who used their reason, a rational creature, i. e. an Angel, ought to preach. But the Gentiles who knew not to use their reason are brought to the knowledge of the Lord, not by words, but by signs; to the one prophecy, as to the faithful; to the other signs, as to the unbelievers. One and the same Christ is preached, when of perfect age, by Apostles; when an infant, and not yet able to speak, is announced by a star to the Gentiles; for so the order of reason required; speaking preachers proclaimed a speaking Lord, mute signs proclaimed a mute infant.
