Origen
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.
But mystically, he who shuns vain-glory calls to a spiritual banquet the poor, that is, the ignorant, that he may enrich them; the weak, that is, those with offended consciences, that he may heal them; the lame, that is, those who have wandered from reason, that he may make their paths straight; the blind, that is, those who discern not the truth, that they may behold the true light. But it is said, They cannot recompense thee, i. e. they know not how to return an answer.
