Same as "Ungeliable". Ungelivable is constructed by Chinese internet users to negate and adjectivize the word of "geli", which is translatrated from Chinese, literally meaning "forcefulness". It is used to express the feeling of unforceful, unsatisfactory, lousy, unpleasant, unfavorable, terrible.

Unreliable, untestable truth

The embodiment of faith.

Oh, you have faith do you?

The next time you feel compelled to use the word 'faith', why don't you try replacing it with: 'pretending to know something that I really don't know''.
If you really want to keep it simple you could just say: 'I have unreliable, untestable truth'.
