Theophylact of Ohrid — as excerpted in the Catena Aurea on Luke 14:12-14

“The supper being composed of two parties, the invited and the inviter, and having already exhorted the invited to humility, He next rewards by His advice the inviter, guarding him against making a feast to gain the favour of men. Hence it is said, Then said he also to him that bade him, When thou makest a dinner or a supper, call not thy friends.”
