Fourth Sunday of Pascha: The Paralyzed Man.
After this there was a feast of the Jews, and Jesus went up to Jerusalem. Now there is in Jerusalem by the Sheep Gate a pool, which is called in Hebrew, Bethesda, having five porches. In these lay a great multitude of sick people, blind, lame, paralyzed, waiting for the moving of the water. For an angel went down at a certain time into the pool and stirred up the water; then whoever stepped in first, after the stirring of the water, was made well of whatever disease he had.
Now a certain man was there who had an infirmity thirty-eight years.
When Jesus saw him lying there, and knew that he already had been in that condition a long time, He said to him, "Do you want to be made well?" The sick man answered Him, "Sir, I have no man to put me into the pool when the water is stirred up; but while I am coming, another steps down before me." Jesus said to him, "Rise, take up your bed and walk." And immediately the man was made well, took up his bed, and walked.
And that day was the Sabbath.
The Jews therefore said to him who was cured, "It is the Sabbath; it is not lawful for you to carry your bed." He answered them, "He who made me well said to me, 'Take up your bed and walk.' " Then they asked him, "Who is the Man who said to you, 'Take up your bed and walk'?" But the one who was healed did not know who it was, for Jesus had withdrawn, a multitude being in that place. Afterward Jesus found him in the temple, and said to him,
See, you have been made well. Sin no more, lest a worse thing come upon you."
The man departed and told the Jews that it was Jesus who had made him well.

Commentary - Saint Theophan the Recluse
Behold, thou art made whole: sin no more, lest a worse thing come unto thee (John 5:14). Sin does not strike only the soul, but the body as well. In some cases this is exceedingly obvious; in others, although not so clearly, the truth remains that the illnesses of the body always stem from sins. A sin is committed in the soul and directly makes it sick; but since the life of the body comes from the soul, then the life coming from a sick soul is of course not healthy. The mere fact that sin brings darkness and sorrow must unfavorably act on the blood, in which lies the basis of bodily health. But when you remember that it separates man from God, the Source of life, and places man in disharmony with all laws acting in himself and in nature, then one must marvel how a sinner remains alive after sinning. This is the mercy of God, Who awaits repentance and conversion. Consequently, a sick person must rush first of all to be cleansed of sins and make peace with God in his conscience. This paves the way for the beneficial action of medicine. They say that there was one distinguished doctor who would not begin treatment until the patient had confessed and received the holy Mysteries; and the more serious the disease, the more urgently he insisted upon this.
