When the devil looks at a man who sincerely desires not to sin, he is not so unintelligent as to suggest to him (as he would to a hardened sinner) that he go and commit fornication or go and steal. He knows we do not want that and he does not set out to tell us something we do not want to hear; but he finds out that little bit of self-will or self-righteousness and through that, with the appearance of well doing, he will do us harm.
Dorotheus of GazaEven if we cannot endure much labor because we are weak let us be set on humbling ourselves.
Dorotheus of GazaIf you cannot be merciful, at least speak as though you are a sinner. If you are not a peacemaker, at least do not be a troublemaker. If you cannot be assiduous, at least in your thought be like a sluggard. If you are not victorious, do not exalt yourself over the vanquished. If you cannot close the mouth of a man who disparages his companion, at least refrain from joining him in this.- St. Isaac the Syrian
Dorotheus of GazaIf one of you sees, sometime, something unedifying and so much as goes on to pass it on and put it into the heart of another brother, in doing so you not only harm yourself but you harm your brother by putting one more little bit of knavery into his heart. Even if that brother has his mind set on prayer or some other noble activity, and the first arrives and furnishes him with something to prate about, he not only impedes what he ought to be doing, but brings a temptation on him. There is nothing graver or more deadly than this doing harm, not only to himself but also to his neighbor.
