It is a big mistake to think that faith is immutable, that it does not change over generations. The longer mankind exists, its faith becomes simpler and stronger. And the simpler and stronger our faith becomes, the better we live. If you believe that faith is the same for all times and that it cannot be changed, you might just as well believe that those fairy tales and proverbs and children's stories which your grandmother told you when you were a small baby are real, and that you ought to believe in them all your life.
