Titus of Bostra — as excerpted in the Catena Aurea on Luke 18:18-23

“Our Lord next declares, that though a man has kept the old covenant, he is not perfect, since he lacks to follow Christ. Thou yet lackest one thing, Sell all that thou hast, &c. As if He says, Thou askest how to possess eternal life; scatter thy goods among the poor, and thou shalt obtain it. A little thing is that thou spendest, thou receivest great things.”
