Theophylact of Ohrid — as excerpted in the Catena Aurea on Luke 19:1-10

“If we examine more closely, we shall see that nothing was left of his own property. For having given half of his goods to the poor, out of the remainder he restored fourfold to those whom he had injured. He not only promised this, but did it. For he says not, “I will give the half, and I will restore fourfold, but, I give, and I restore. To such Christ announces salvation; Jesus saith unto him, This day is salvation come to this house, signifying that Zacchæus had attained to salvation, meaning by the house the inhabitant thereof. And it follows, forasmuch as he also is a son of Abraham. For He would not have given the name of a son of Abraham to a lifeless building.”
