If a thing happens once, it can happen again. If any human being has ever realised perfection, we too can do so. If we cannot become perfect here and now, we never can in any state or heaven or condition we may imagine.
... the good for man is an activity of the soul in accordance with virtue, or if there are more kinds of virtue than one, in accordance with the best and most perfect kind.
The measure of charity may be taken from the want of desires. As desires diminish in the soul, charity increases in it; and when it no longer feels any desire, then it possesses perfect charity.
