John Chrysostom
Catena Aurea · Lukasevangelium 14
Then said he also to him that bade him, When thou makest a dinner or a supper, call not thy friends, nor thy brethren, neither thy kinsmen, nor thy rich neighbours; lest they also bid thee again, and a recompence be made thee. But when thou makest a feast, call the poor, the maimed, the lame, the blind: And thou shalt be blessed; for they cannot recompense thee: for thou shalt be recompensed at the resurrection of the just.
(Hom. 1, 3. in ep. Col.) Many are the sources from which friendships are made. Leaving out all unlawful ones, we shall speak only of those which are natural and moral; the natural are, for instance,between father and son, brother and brother, and such like; which He meant, saying, Nor thy brethren, nor thy kinsmen; the moral, when a man has become your guest or neighbour; and with reference to these He says, nor thy neighbours.
