Context

“Whether Those Things That Are of Faith Can Be an Object of Science [*Science is certain knowledge of a demonstrated conclusion through its demonstration] ? Objection 1: It would seem that those things that are of faith can be an object of science. For where science is lacking there is ignorance, since ignorance is the opposite of science. Now we are not in ignorance of those things we have to believe, since ignorance of such things savors of unbelief, according to 1 Tim. 1:13: "I did it ignorantly in unbelief." Therefore things that are of faith can be an object of science.” source
