If he really thinks that, I hope he also doesn't take any photographs as they might qualify as graven images of things on the earth.
Granted, some Catholic laity around the world seem to relate to the statuary of Catholic churches as pagans do to idols --praying to them. Missing the point that God is Spirit --and He is everywhere --and we do not reach Him or praise Him through a statue. But I believe Catholic doctrine denies deifying and worshiping Mary. Maryology is a medieval development --and some say it improved the lot of women and mothers. Some say it is an adaptation of the Mother Earth/Mother/Goddess pagan worship. Whatever, Mary is a special lady who found favor with God --and did all that God asked of her.
I think the creche scenes such as we enact in our church Christmas programs are, like the Christmas carols, re-telling the "greatest story ever told." Drama was one way the medieval church told Bible stories before people had access to the Bibles --"morality plays," they called them. Re-enactments of this timeless, true tale help to make the story come alive again and again --
The Virgin Mary had a Baby Boy --
Immanuel, God with Us --
He shall save His people from their sins!
Glory to the new born king!
Joy to the world --the Lord has Come!
He rules the world --with Truth and Grace!
"God is not willing that any should perish, but that all should come to repentance and have eternal life."--the Bible
