“Dear friends, we possess many true witnesses about Christ. The heavenly Father bears witness through the Son; the Holy Spirit bears witness, descending bodily in the form of a dove; the archangel Gabriel bears witness, bringing the glad tidings to Mary; the Virgin Theotókos bears witness to him; the blessed place of his manger bears witness on his behalf.”Cyril of Jerusalem, Catecheses 10, 19; PG 33, 685 A.
