“On the wall behind them is Molech”
Molech? Umm, Moloch usually isn’t represented with the dove of the Holy Spirit, or Christian crosses, or angels. Looks more like some artist’s take on Christian iconography.
Looks like a sacrifice is taking place. Just good, clean, wholesome, Christian artwork for a child’s room. Probably just an artist’s rendering of the Holy Eucharist. Nothing weird or about it.
Four point crosses are the sign of Mithras, and have nothing to do with our savior's crucifixion.
