On relations with non-Christians
686. Another Christ-loving layperson asked the same Old Man: I want to press some Jewish wine in my presser. Is this a sin?
Response by John
If, when God rains, it rains in your field but not in that of the Jew, then do not press his wine. If he is loving-kind to all and rains upon the just and the unjust (cf. Mt 5.45), then why do you want to be inhumane and not compassionate, rather, as he says: “Be merciful, even as your Father in heaven is merciful” (Lk 6.36).
