Quotes from the Saints
The Four Hundred Chapters on Love:
334.Do not recall in time of peace what your brother said in time of hurt, even though the offensive things were said to your face, or were said to another about you and you heard them afterward, lest in retaining grudges you revert to pernicious hate for your brother.
342. When you neither say nor do anything intentionally shameful, nor bear any grudge against the one who has harmed you or spoken ill of you, and when in time of prayer you always keep your mind free of matter and form, then know that you have reached the full measure of detachment and perfect love.
343. It is no small struggle to be delivered from vainglory; however, one is delivered by the discreet practice of virtue and more frequent prayer. An indication of this deliverance is to bear no more grudges against anyone who offends us now or has offended us in the past.
St. Maximus the Confessor
