Do not require a return for benefits bestowed. Hear what is written, ‘When you make a dinner or a supper, do not call your friends, nor your brethren, neither your kinsmen, nor your rich neighbors, lest they also invite you later in recompense. But when you make a feast, call the poor, the maimed, the lame, the blind: and you shall be blessed; for they cannot give recompense’ (Lk. 14:12 ff.).
St. Gregory the Great
