Marcos 8:3
[(as quoted by Aquinas, AD 1274)] (in Luc. 6:73) The good Lord indeed whilst He requires diligence, gives strength; nor will He dismiss them fasting, lest they faint by the way, that is, either in the course of this life, or before they have reached the fountainhead head of life, that is, the Father, and have learnt that Christ is of the Father, lest haply, after receiving that He is born of a virgin, they begin to esteem His virtue not that of God, but of a man. Therefore the Lord Jesus divides the food, and His will indeed is to give to all, to deny none; He is the Dispenser of all things, but if thou refusest to stretch forth thy hand to receive the food, thou wilt faint by the way, nor canst thou find fault with Him, who pities and divides. — Catena Aurea by Aquinas
Marcos 8:23
Therefore, he recognizes himself as a human who seeks refuge in the baptism of Christ. And so, he put clay on you, that is, modesty, prudence, consideration of your weakness; and he said to you: Go to Siloam. What is Siloam? It is translated as 'sent', that is: Go to that fountain in which the cross of the Lord is proclaimed: go to that fountain in which Christ redeemed the errors of all. You, who have been baptized, have come to the altar, and have begun to see things which you had not seen before. This happened when your eyes were opened by the fountain of the Lord and the preaching of His passion. You, who were blind in heart, have begun to see the light of the sacraments. — On the Sacraments
