Cyril of Jerusalem on Mother of God

From the book 

"The Faith of the Early Fathers"

 By William A. Jurgens

Cyril of Jerusalem (315-386) was a distinguished theologian and archbishop of Jerusalem in the early Church.

19. Many, my beloved, are the true testimonies concerning Christ. The Father bears witness from heaven of His Son: the Holy Ghost bears witness, descending bodily in likeness of a dove: the Archangel Gabriel bears witness, bringing good tidings to Mary: the Virgin Mother of God bears witness: the blessed place of the manger bears witness.
