To have
unshakable faith, you have to find it yourself. It can not be had via
indoctrination. It depends on
choice, man, conscious choice. If you don't
think for yourself, all your
precepts can be
shaken from
outside. It requires
faith in yourself, or maybe just
faith in faith.
It doesn't require obedience or allegience. It is an end unto itself. It is irrational, like love. It is humble, what is known completely need not be evangelized.
Unshakable faith in invisible pink unicorns is fine, as long as you haven't been browbeaten into it.
