Mary is the subject of much veneration in the Roman Catholic Church
and the Eastern Orthodox Church; but within Protestant Traditions,
(while she is "highly regarded"); Protestants stick closely to the
facts recorded in the New Testament about her. Protestants accept
"the virgin birth of Jesus" as Mary conceived Jesus through the
power of the Holy Spirit. But afterwards, Mary and Joseph had
several more children with Jesus having many younger brothers and
sisters including his half-brother, James, the leader of the church
at Jerusalem.
