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.
