The words of Joseph Volotsky (persecutor of "judaizers"/christians in the Novgorod region)
"We will now open the words of Godly Chrysostom, when he says: "we shouldn't detest any person or do him evil, even if he is a wicked person or a heretic" This great and equal to the apostles man points to specific temporary conditions, because it is not the will of God that this should be always so. Great Chrysostom testifies that we shouldn't do evil or detest any man, be he wicked or heretical, UNTIL HE CAUSES US SPIRITUAL HARM
If godly shepherds see an unbeliever or a heretic, who isn't doing any spiritual harm, let him go, to learn the letter, or to admonish him with all meekness and humility. If, on the other hand, they see the wretched heretic, worse than any wolf attempting to destroy and pervert Christ's flock - then it is befitting not only to detest and condemn him, but to curse and give the blasphemer wounds, which will sanctify your hand. That is what holy Chrysostom is saying.
So did Leo, bishop of Catania, he didn't condemn Heliodor, the heretic, at once, but when Heliodor went into the church and started doing some kind of spell, to seduce the godly, Leo went out of the church and burned Heliodor with fire, then got in and performed the godly service. (!!!!!!!)
Such judgement (condemnation) did the righteous perform - and were not condemned for it. Agreeing with this is the teaching of Chrysostom:
"Whatever happens according to the will of God, even if it seems evil, is the ultimate good, and whatever is against the will of God and is not pleasing to him, could seem good, but it is the ultimate evil and a lawless deed. If anyone murders according to the will of God- this murder is better than any love for man, if anyone shows mercy from love, but it is against the will of God, that mercy surpasses any murder. What makes man good or bad is not the nature of things, but the will of God" - Chrysostom
Joseph Volotsky is also known to have been a staunch opponent of the heretical sect which was spreading in Russia at that time ("Judaizers"). During the Church Sobor of 1504, he demanded that all heretics be executed by the state.
In his major work, called The Enlightener (Просветитель), which consisted of 16 chapters, he tried to prove the wrongfulness of the "new teaching" in order to be able to prosecute the heretics and convince people not to believe in the sincerity of their repentance. Taking inspiration from the Roman-Byzantine treatment of heresiarchs and the Dominican-led persecutions in Spain and Portugal, he called for a civil inquisition against heretics and championed their imprisonment and execution. As with the controversy over monastic ownership of estates, Joseph Volotsky was opposed in this matter by St. Nil Sorsky.
