Gregory the Great — as excerpted in the Catena Aurea on Luke 14:15-24

“(in Hom. 36. in Ev.) By the bodily senses also because they cannot comprehend things within, but take cognizance only of what is without, curiosity is rightly represented, which while it seeks to shake off a life which is strange to it, not knowing its own secret life, desires to dwell upon things without. But we must observe, that the one who for his farm, and the other who to prove his five yoke of oxen, excuse themselves from the supper of their Inviter, mix up with their excuse the words of humility. For when they say, I pray thee, and then disdain to come, the word sounds of humility, but the action is pride. It follows, And this said, I have married a wife, and therefore I cannot come.”
