Who gives you the day will give you also the things necessary for the day. - Gregory of Nyssa

Paul ... calls the process of shifting away from material matters and toward spiritual matters a “turning to the Lord” and “taking away of a veil.” In all the different tropes and terms for the theoria-meaning, Paul instructs us in a single form of teaching: it is not necessary always to remain in the letter, on the grounds that the immediately apparent meaning of the things said in many instances causes us harm in the pursuit of the life of virtue. But it is necessary to pass over to the incorporeal and spiritually intelligible reading with insight, with the result that the more corporeal meanings are converted to an intellectual sense and meaning, in the same way that the dust of the more fleshly significance of what is said is “shaken off.” This is why Paul says, “the letter kills, but the spirit gives life,” since oftentimes with biblical narrative, it will not provide us with examples of a good life if we stop short at the simple events.

Virtue is achieved by its seekers not without a struggle; nor is abstinence from the paths of pleasure a painless process to human nature.

Now those who take a superficial and unreflecting view of things observe the outward appearance of anything they meet, e.g. of a man, and then trouble themselves no more about him. The view they have taken of the bulk of his body is enough to make them think that they know all about him. But the penetrating and scientific mind will not trust to the eyes alone the task of taking the measure of reality; it will not stop at appearances, nor count that which is not seen among unrealities. It inquires into the qualities of the man's soul.
