Someone who has actually tasted truth is not contentious for truth. Someone who is considered by people to be zealous for truth has not yet learned what truth is really like; once he has truly learned it, he will cease from zealousness on its behalf.
Isaac the SyrianMore Isaac the Syrian quotes
Love sinners, but hate their deeds, and do not disdain sinners for their failings, so that you yourself do not fall into the temptation in which they abide... Do not be angry at anyone and do not hate anyone, neither for their faith, nor for their shameful deeds... Do not foster hatred for the sinner, for we are all guilty... Hate his sins, and pray for him, so that you may be made like unto Christ, who had no dislike for sinners, but prayed for them.
Isaac the Syrian
