The Bible itself states that other things happened.
You believe that the Blessed Virgin had other children, yet this FALSEHOOD is found nowhere in scripture.
You believe that the Lord didn't found His Church on Peter's confession, though this FACT is in scripture.
I have never once seen you refer to the Blessed Virgin as "blessed," you merely call her Mary, even though the Bible implores you to do otherwise.
What about Mark 3 in re: physical brothers and sisters.
We believe that the foundation of the church is that of Peter's confession that Jesus is the messiah.
"The Bible itself states that other things happened."
I don't understand where you are going with this statement.
