"Mary's Davidic descent is common among the Church Fathers. St. Paul's own statement that Jesus was “born of the seed of David according to the flesh” confirms this. According to John of Damascus, Luke's genealogy is that of Mary, while Matthew describes the genealogy of Joseph. St. John of Damascus' hypothesis was promoted by Annius of Viterbo in 1502 and has since gained widespread acceptance. Luke's genealogy would account for Mary's Davidic descent, first hypothesized by Irenaeus of Lyon, and Jesus would be “son of David” even according to the flesh, making the prophecy of Psalm 131:11 and the announcement of the Angel Gabriel to Mary Most Holy true. St. Thomas Aquinas added to St. Irenaeus' hypothesis that Mary belonged to the tribe of Levi on her mother's side, like Elizabeth, her relative (Luke 1:5, 36)."
