“One should not educate a child to believe something that is correct only for one’s childhood and that has to be changed for more correct beliefs later on, erroneously assuming that ‘he will understand when he grows up.’
On the contrary, a child has to be helped to understand in accordance with his capacities, but what he learns has to be correct, so that even when he grows up he won’t find any discrepancies and it will still be correct.”
–Rabbi Adin Steinsaltz
