Origen — as excerpted in the Catena Aurea on Luke 14:12-14

“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.”
