In no way is that indoctrination or brainwashing, by the way. Look at you! Allowing your children to think for themselves!
By the way, I have a wonderful Bible verse, or three, that your children can copy!
"Then you shall eat the offspring of your own body, the flesh of your sons and of your daughters whom the Lord your God has given you" - Deuteronomy 28:53
"The King asked her, 'What’s the matter?' This woman said to me, 'Give up your son so we may eat him today, and tomorrow we'll eat my son.' So we cooked my son and ate him. The next day I said to her, 'Give up your son so we may eat him,' but she had hidden him....The king said, behold, this evil is of the Lord." - 2 Kings 6:28-29,33
"And I the Lord will cause them to eat the flesh of their sons and the flesh of their daughters, and they shall eat every one the flesh of his friend." - Jeremiah 19:9
"Behold, I the Lord will corrupt your seed, and spread dung upon your faces, even the dung of your solemn feasts; and one shall take you away with it." - Malachi 2:3
There you go! Have them copy *those*!
