We believe that the Blessed Virgin was not just a conduit or channel for the Son of God to come into the world. Instead he took his human flesh from his human mother. In other words Jesus would have looked like Mary, and Mary would have resembled Jesus. I guess if you want to see what Mary looked like you would have to imagine the man of the Shroud of Turin, but in female form and not so beat up.
Fr. Longenecker is an interesting person. After graduating from the fundamentalist Bob Jones University he went on to study theology at Oxford University. He was ordained as an Anglican priest and served as a curate, a chaplain in Cambridge and a country parson.
In 2006 he was ordained as a Catholic priest under the special pastoral provision for married former Anglican clergy. Here he is pictured with his wife and four children and an unidentified bishop.
