St. John Climacus
“I have rebuked people who were engaged in slander, and, in self-defense, these evildoers claimed to be acting out of love and concern for the victim of their slander. My answer to that was to say: ‘Then stop that kind of love, or else you will be making a liar out of him who declared, ‘I drove away the man who secretly slander his neighbor’ (Ps. 100:5). If, as you insist, you love that man, then do not be making a mockery of him, but pray for him in secret, for this is the kind of love that is acceptable to the Lord. And remember – now I say this as something to be pondered, and do not start passing judgment on the offender – Judas was one of the company of Christ’s disciples and the robber was in the company of killers. Yet what a turnabout there was when the decisive moment arrived!'”
