The patristic rule stated that the genealogy was always recorded from the father’s bloodline and not the mother’s. Luke honors that, but includes that of Mary.
The idea that Jesus’ mother was a virgin when He was born, is difficult to grasp. Medically speaking you need a man and a woman to have a baby.
In this article I would like to focus on an aspect of the virgin birth that we easily overlook if we do not pay attention to the genealogy of Jesus.
