These are not my rules.
I can’t make sense of those rules, whoever they belong to.
It seems to me that if an image or statue, book or t-shirt, postcard or travel mug, leads me to prayer, and closer to God, then it can’t be intrinsically evil.
Many Protestants seem to agree, since I see paintings of Jesus, travel mugs, t-shirts, key-chains, and inspirational quotations, in Protestant bookstores.
