He came to the place where a great multitude of sick people lay: the blind, the lame, and the withered. Although He was the Physician of souls and bodies, and had come to heal all the souls of believers, He chose one from among all the sick.
By this He showed the unity of the Church.
If we consider what He did with a simple heart, using human understanding and knowledge, then from the standpoint of His power He did nothing great. From the standpoint of His generosity, He did too little.
So many lay there, and He cared for only one, though by a single word He could have raised them all. What then should we think, except that His power and goodness acted chiefly so that souls might understand eternal salvation through His deeds?
It was not chiefly so that bodies might deserve passing health. For the true health of bodies, which is awaited from the Lord, will come at the end of the ages, at the resurrection of the dead.
Then he who lives will die no more. Then he who is healed will be sick no more. Then he who is nourished will hunger and thirst no more. Then he who is renewed will grow old no more.
But the eyes of the blind, opened then by the works of our Lord and Savior Jesus Christ, were closed again in death. The limbs of the paralytics, which then received strength, were destroyed in death.
Everything temporarily healed in mortal limbs finally passed away. But the soul that believed prepared its passage to eternal life.
Therefore, to that soul for whose forgiveness of sins He came, and which was ready to acknowledge that He humbled Himself for the healing of its bodily sicknesses, He gave a great sign in the healing of that sick man.
Concerning the deep meaning of this deed and sign, I will speak to you as far as the Lord grants by His generosity and as far as I am able. Listen attentively, and support my weakness by your prayer.
If I cannot interpret something, He will reveal it to you, by whose help I do what I can.
I remember that we have often enough discussed that pool surrounded by five porches, in which lay a great multitude of sick people. I am about to say what many together with me will remember rather than learn as something new.
Yet there is nothing wrong if what is already known is repeated, so that those who did not yet know may be enlightened, and those who already know may be strengthened in this knowledge.
Therefore I must touch briefly on what is already known, rather than examine it slowly.
It seems to me that that pool and that water signify the Jewish people. For "waters" is used as a name for peoples, as the Apocalypse of John shows us most clearly. When many waters were shown to him and he asked what they meant, he received the answer that they are peoples (cf. Rev 17:15).
Thus that water, that is, that people, was enclosed in the Pentateuch of Moses, as though in five porches. Yet those books showed the sick; they did not heal them.
For the Law accused sinners, but did not free them from sin. The letter without grace made men guilty, while grace freed from sins those who confessed them.
The Apostle speaks precisely about this: "For if a law had been given which could make alive, then righteousness would indeed be by the law" (Gal 3:21).
Why, then, was the Law given? He continues and says, "But the Scripture has confined all under sin, that the promise might be given to believers through faith in Jesus Christ" (Gal 3:22).
What could be clearer? Have these words not explained to us both the five porches and the multitude of the sick? The five porches are the Law.
Why did the five porches not heal the sick? Because "if a law had been given which could make alive, then righteousness would indeed be by the law."
Why did they hold those whom they did not heal? Because "the Scripture has confined all under sin, that the promise might be given to believers through faith in Jesus Christ."
What happened, then, that those who could not be healed in the porches were healed in the troubled water? The water was seen suddenly to be troubled, but He who troubled it was not seen.
You may think that this happened by the power of an Angel. Yet it was not without a certain mystery containing a sign. After the water was troubled, one man went down into it, and he alone was healed.
Whoever entered after him did so in vain. What does this mean, if not that Christ came alone to the Jewish people? By doing great works and teaching useful things, He troubled sinners.
By His presence He troubled the water and stirred them to violence against Himself. But He troubled them while remaining unknown.
"For if they had known, they would never have crucified the Lord of glory" (1 Cor 2:8). Thus to descend into the troubled water means to believe humbly in the Lord's Passion.
There one man was healed, which pointed to the unity of the Church. Whoever came afterward was not healed, because anyone outside the unity of the Church cannot be healed.
