"Let us not, therefore, be insensible to His kindness. For were He to reward us according to our works, we should cease to be. Therefore, having become His disciples, let us learn to live according to the principles of Christianity. For whosoever is called by any other name besides this, is not of God. Lay aside, therefore, the evil, the old, the sour leaven, and be changed into the new leaven, which is Jesus Christ. Be salted in Him, lest any one among you should be corrupted, since by your savour you shall be convicted. It is absurd to profess Christ Jesus, and to Judaize. For Christianity did not embrace Judaism, but Judaism Christianity, that so every tongue which believes might be gathered together to God." St. Ignatius of Antioch, Epistle to the Magnesians

"Consider, then, with whom they are sharing their fasts. It is with those who shouted: "Crucify him, Crucify him", with those who said: "His blood be upon us and upon our children". If some men had been caught in rebellion against their ruler and were condemned, would you have dared to go up to them and to speak with them? I think not. Is it not foolish, then, to show such readiness to flee from those who have sinned against a man, but to enter into fellowship with those who have committed outrages against God himself? Is it not strange that those who worship the Crucified keep common festival with those who crucified him? Is it not a sign of folly and the worst madness?" St. John Chrysostom
