As a result the radicals can creep in and as teachings change the congregation will follow. A case in point being the expansion of Mary from the Mother of Jesus to this creation we see today. The Mary of today was born without sin,was a virgin forever, was assumed into heaven, she magnifies prayers, she appears in visions to bring messages from God, she cures those that are obedient to her.
None of these changes about Mary occur in churches where there is a requirement that all teaching and belief must be consistent with Scripture. These changes only occur where other sources are considered coequal of Scripture for measuring the validity of teaching and belief.
One would think if that if the Mother Church was indeed devine it wouldn't bounce around between Latin Mass and the common language, or any of the other issues that just seem to keep bouncing around in St Pete's.
My pastor, who was Catholic all his life until he was born again, said just this morning that this teaching about Mary being sinless was a false teaching. FOR ALL HAVE SINNED, and fallen short of the glory of God, the Bible tells us. ALL means Mary as well. She also recognized her need for a Saviour, calling Jesus Saviour herself. Looks pretty clear to me.
