In the ancient times, the newly-converted European cultures naturally reused their native "pagan" words to refer to some of the newly-acquired Christian concepts, rather then re-inventing the wheel. Were there, in the history of Early-Christianity, conservative priests or people who were opposed to such naming, mainly in the case of Latin people naming the Christian God "Deus" (which once had a "pagan" sense), by calling such thing an "heresy", "idolatry", "paganism", etc?
Other cases are Latin "Inferno" and Greek "Hades", formerly Roman and Greek mythology concepts, that came to refer to the Christian hell in the Latin and Greek languages, respectively (but I think those cases might be not as heretic as attributing the name of pagan god(s) to God). How strongly was this objected to?
