Elder St Paisios on Knowing When to React
“When a spiritual person tries to defend himself indignantly in a personal matter, this is clearly selfish, an act of temptation. Such a person is subject to external demonic influences. If someone is being wronged or ridiculed, others should defend him, for the sake of justice, not for their own self-interest. It is not right for you to quarrel on your own behalf. It is, of course, another matter if you react to defend serious spiritual matters, matters that relate to our faith, to Orthodoxy. You have a responsibility to do this.”
