The content of eternal truth, of principles of truth, is grasped by subjection of our will to the Christian message, and the consequent experience out of this subjection. This experience is given by grace; it is not produced by human activities. Here the term “experience” becomes important. Experience, again, must be distinguished from what we mean today by “experience,” if we mean anything at all – -which is very questionable, since the word has such a large use that it almost has become meaningless. In any case at that time experience means not religious experience, generally speaking – such a thing ” didn’t exist at that time — but experience meant participation in the objective truth which is implied in the Bible and which is authoritatively explained by the Church Fathers.
