Thank you for helping us make our case. Oh, BTW the "Holy Family" is a Catholic invention developed by St. Francis of Assisi.
If the siblings of the Lord are from a prior wife why didn't these children accompany Joseph and Mary to Bethlehem to be counted in the census and then on to Egypt? When Jesus was 12 and Joseph and Mary lost track of Him it is possible they had their hands full with their other children and thought Jesus was with friends and relatives in the caravan. There are a multitude of possible scenerious that are immaterial to the focus of the Bible and the life of Christ.
Why is the Bible silent on the parents of most of the apostles and why is the Bible silent on Joseph's supposed first wife?
Paul refers to James as the Lord's brother and the people of Jesus' hometown list Mary and then Jesus' siblings, which indicates (to those who know Jewish custom) they knew Mary was their biological mother.
Why do Catholics bend over backwards in an attempt to disprove Biblical truth?
