For E.W.N.
Credibilium tria sunt genera. Alia sunt quae semper creduntur et numquam intelleguntur: sicut est omnis historia, temporalia et humana gesta percurrens. Alia quae mox, ut creduntur, intelleguntur: sicut sunt omnes rationes humanae, vel de numeris, vel de quibuslibet disciplinis. Tertium, quae primo creduntur, et postea intelleguntur: qualia sunt ea, quae de divinis rebus non possunt intelligi, nisi ab his qui mundo sunt corde.
There are three kinds of credible things: those that are always believed and never understood: such is all history, such are all temporal things and human actions. Those that are understood as soon as they are believed: such are all human reasonings, concerning numbers or any other discipline. Third, those that are believed first and understood afterward: such are those concerning divine things, which can only be comprehended by the clean of heart.
– St. Augustine,Of Various Questions, LXXXIII, 48
