Morphology
The phrase combines 'act' (a deed) with 'faith' (trust or belief) in a straightforward compositional way: an action motivated by faith. This is a common noun + of + noun pattern found across languages, so a B1 learner who knows the constituents would very likely infer the intended meaning.
Etymology
Act of faith comes from religious life, where someone made a clear act, like lighting a candle or making a vow, to show their faith even when there was no proof. So today act of faith means 'an action you take because you trust or believe, not because you know for sure'.
