“Let us further see where blessed Elijah found that widow, dearly beloved. She had gone out to get water and to pick up sticks of wood. Let us now consider what the water and the wood signify. We know that both are very pleasing and necessary for the church, as it is written: "He is like a tree planted near running water." In the wood is shown the mystery of the cross, in the water the sacrament of baptism. Therefore, she had gone out to gather two sticks of wood, for thus she replied to blessed Elijah when he asked her for food: "As the Lord lives, I have nothing but a handful of meal and a little oil in a cruse; and behold, I am going out to gather two sticks that I may make food for me and my son … and we will eat it and die." The widow typified the church, as I said above; the widow's son prefigured the Christian people. Thus, when Elijah came, the widow went out to gather two sticks of wood. Notice, brothers, that she did not say three or four, nor only one stick; but she wanted to gather two sticks. She was gathering two sticks of wood because she received Christ in the type of Elijah; she wanted to pick up those two pieces because she desired to recognize the mystery of the cross. Truly, the cross of our Lord and Savior was prepared from two pieces of wood, and so that widow was gathering two sticks because the church would believe in him who hung on two pieces of wood. For this reason that widow said, "I am gathering two sticks that I may make food for me and my son, and we will eat it and die." It is true, beloved; no one will merit to believe in Christ crucified unless he dies to this world. For if a person wishes to eat the body of Christ worthily, he must die to the past and live for the future.”

“And as she was going to fetch it,.... For she made no difficulty of granting his request, but immediately set out to fetch him some water from the city, or some spring close by, or her own house; being very ready to do an hospitable act to a stranger, and especially to a good man, and a prophet, as she might perceive by his habit he was, as it seems by what follows: and said, bring me, I pray thee, a morsel of bread in thine hand; to eat before he drank; this he said still further to try her whether she was the person that was to sustain him, as well as in order to lead on to more discourse with her.”

The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
