It is impossible that one who has turned to the world and feels its anxieties, and engages his heart in the wish to please men, can fulfill that first and great commandment of the Master, 'You shall love God with all your heart and with all your strength' (Mt. 22:37).
Gregory of Nyssa[Jews are] murderers of the Lord, assassins of the prophets, rebels against God, God haters,... advocates of the devil, race of vipers, slanderers, calumniators, dark-minded people, leaven of the Pharisees, sanhedrin of demons, sinners, wicked men, stoners, and haters of righteousness.
Gregory of NyssaFor truly barren is profane education, which is always in labor but never gives birth. For what fruit worthy of such pangs does philosophy show for being so long in labor? Do not all who are full of wind and never come to term miscarry before they come to the light of the knowledge of God, although they could as well become men if they were not altogether hidden in the womb of barren wisdom?
