Anytime you bring God into it... the concept of truth has the option of getting very abstract.

It's pretty common, for example, to believe that God is on our side and we will win the war or somesuch. Actually walking onto a battlefield with a literal expectation of divine intervention... much less as common. Pious generals still believe in tactics, steel and suchlike. Not always... but usually.

European pre-modern writers were mostly very pious. The works preserved are likewise very pious. Greek philosophers were often closer to atheists than later Christians.
