If the founder of Christianity had plainly said: 'It is not necessary to believe in order to be saved; it is only necessary to do, and he who really loves his fellow-men, who is kind, honest, just and charitable, is to be forever blest' - if he had only said that, there would probably have been but little persecution.

When your little child tells a lie, do not rush at him as though the world were about to go into bankruptcy. Be honest with him. A tyrant father will have liars for his children; do you know that?
