How do you know what Jesus looked like in order to paint an “image” of Him? How do you know what Mary looked like in order to claim she is seen in an “apparition”? You are not showing “images of Jesus or Mary”. You have no idea what they looked like. You are creating man’s image and calling that image “Christ” or “Mary”, or whoever it is you decide to venerate. When I say “you” I am talking plural, as in “you”, the RCC.
Ok, your judgement will have to do for now:
Are the paintings idols?
I don’t know what He looked like but for an artist to depict how he imagines Jesus looked is not the same thing as depicting an non existent false or demonic deity and adoring it with the worship due to God alone.
