Excerpt from the Commentary on the Healing of the Paralytic, by Saint John Chrysostom

What manner of cure is this? What mystery doth it signify to us? For these things are not written carelessly, or without a purpose, but as by a figure and type they show in outline things to come, in order that what was exceedingly strange might not by coming unexpectedly harm among the many the power of faith. What then is it that they show in outline? A Baptism was about to be given, possessing much power, and the greatest of gifts, a Baptism purging all sins, and making men alive instead of dead.

On the Sunday of the Paralytic Man

One man was there, who had been ill for thirty-eight years. When Jesus saw him and knew that he had been lying there a long time, he said to him, “Do you want to be healed?” The sick man answered him, “Sir, I have no man to put me into the pool when the water is troubled, and while I am going another steps down before me.” Jesus said to him, “Rise, take up your pallet, and walk.”
