Catena Aurea on John 5:1–13: Augustine of Hippo

Judging on low and human notions of this miracle, it is not at all a striking display of power, and only a moderate one of goodness. Of so many, who lay sick, only one was healed; though, had He chosen, He could have restored them all by a single word. How must we account for this? By supposing that His power and goodness were asserted more for imparting a knowledge of eternal salvation to the soul, than working a temporal cure on the body. That which received the temporal cure was certain to decay at last, when death arrived: whereas the soul which believed passed into life eternal. The pool and the water seem to me to signify the Jewish people: for John in the Apocalypse obviously uses water to express people. (Rev. 17:15.)
