Wrath that is nursed in the heart, although it may not injure men who stand by, yet excludes the splendour of the radiance of the Holy Ghost, equally… - John Cassian

It is possible that those who are in no way pressed down with the weight of money may be condemned with the covetous in disposition and intent. For it was the opportunity of possessing which was wanting in their case, and not the will for it.

With the increase of wealth the mania of covetousness increases.

Sometimes when we have been overcome by pride or impatience, and we want to improve our rough and bearish manners, we complain that we require solitude, as if we should find the virtue of patience there where nobody provokes us: and we apologize for our carelessness, and say that the reason of our disturbance does not spring from our own impatience, but from the fault of our brethren. And while we lay the blame of our fault on others, we shall never be able to reach the goal of patience and perfection. The chief part then of our improvement and peace of mind must not be made to depend on another's will, which cannot possibly be subject to our authority, but it lies rather in our own control. And so the fact that we are not angry ought not to result from another's perfection, but from our own virtue, which is acquired, not by somebody else's patience, but by our own long-suffering.
