In the teaching of St. Silouan and Elder Sophrony, people are not classified as enemies and friends, bad and good, but people who have known God and people who have not known God. Wherever enemies are acknowledged, it means part of the body of humanity is cast aside and universality is restricted. Keeping the commandment of love for ones enemies, man embraces all human beings and becomes catholic and universal. On an ecclesiastical level, love for ones enemies comprises the criterion that ensures catholicity. – Prof. George Mantazaridis, quoted in Patristic Theology, – Fr. John Romanides
