Hebrews 7:14

[Africanus on the Genealogy in the Holy Gospels . Some indeed incorrectly allege that this discrepant enumeration and mixing of the names both of priestly men, as they think, and royal, was made properly, in order that Christ might be shown rightfully to be both Priest and King; as if any one disbelieved this, or had any other hope than this, that Christ is the High Priest of His Father, who presents our prayers to Him, and a supramundane King, who rules by the Spirit those whom He has delivered, a cooperator in the government of all things. And this is announced to us not by the catalogue of the tribes, nor by the mixing of the registered generations, but by the patriarchs and prophets. Let us not therefore descend to such religious trifling as to establish the kingship and priesthood of Christ by the interchanges of the names. …

Orth. So again the divine apostle, reminding us of the blessing of Judah, and pointing out how it received its fulfilment exclaims “For it is evident that our Lord sprang out of Judah.” So too the Prophet Micah and the evangelist Matthew. For the former spoke his prediction, and the latter connects the prophecy with his narrative. What is extraordinary is that he says that the open enemies of the truth plainly told Herod that the Christ is born in Bethlehem, for it is written, he says, “And thou Bethlehem in the land of Judah art not the least among the Princes of Judah for out of thee shall come a Governor who shall rule my people Israel.” Now let us subjoin what the Jews in their malignity omitted and so made the witness imperfect. …

The angel of the Lord was sent to the holy Virgin, who was descended from David’s line. For it is evident that our Lord sprang out of Judah, of which tribe no one turned his attention to the altar , as the divine apostle said: but about this we will speak more accurately later. And bearing glad tidings to her, he said, Hail thou highly favoured one, the Lord is with thee . And she was troubled at his word, and the angel said to her, Fear not, Mary, for thou hast found favour with God, and shalt bring forth a Son and shalt call His name Jesus ; for He shall save His people from their sins. Hence it comes that Jesus has the interpretation Saviour. And when she asked in her perplexity, How can this be, seeing I know not a man ? the angel again answered her, The Holy Spirit shall come upon thee, and the power of the Highest shall overshadow thee. …
