Could be. Back then it didn't matter as much, because Islam wasn't invented.
It came from an Afghanistan banana stand.
Almost certainly. That bright blue pigment is lapis lazuli, and Afghanistan was the major source of lapis lazuli.
Those pictures aren't Christian. They're catholic. And it's not really Mary.
Catholicism didn't exist for over 300 years after Jesus. Catholicism is never true, and never from God. The "pope's" religion is catholic. There is no "pope" in the Bible. Every "pope" is a false prophet working for satan. And catholicism teaches a false gospel of works that leads to hell, and has tons of other false doctrines as well. Catholicism is lies and falsehoods that lead to hell. Catholicism is to be avoided.
.The truth is that Jesus is God. Jesus loves you! Death leads to immediate heaven or hell, and it is too late to be saved, after death. The only way to heaven is by believing in Jesus. The truth is that believing in Jesus to take you to heaven apart from any of your works, is the only way to heaven. Jesus paid it all, so believe in Jesus, and you're saved. There is no chance to be saved after death. Jesus Christ is God, Jesus died on the cross to pay for all of our sins, all sins past and future, to make all our sins forgiven, past and future, and then Jesus resurrected from the dead. Nothing else pays for our sins, not works or deeds or religions or anything. You cannot add any works to salvation (Romans 4:5). So to be in heaven and not in eternal torment in the lake of fire, believe in Jesus Christ to take you to heaven. That easy! Tell Jesus right now that you believe in Jesus for eternal life, and you will be in heaven! Jesus loves you and wants to bless you now and throughout your life and forever!
