On Relations with Heterodox and Unbelievers

St. Anatoly of Optina 1824-1894

Do not fear sorrows, but fear the stubbornness of heretics who try to separate a man from Christ, which is why Christ commanded us to consider them as pagans and pharisees. (Living Without Hypocrisy, p. 48)

St. Nektary of Optina 1853-1928

One may have a good worldly relationship with nonbelievers, but one cannot have a relationship in prayer and one must not carry on arguments about religion so that the name of God not be offended during an argument. (ibid., p. 98)
