Catena Aurea on John 5:24: Augustine of Hippo

If in hearing and believing is eternal life, how much more in understanding? But the step to our piety is faith, the fruit of faith, understanding. It is not, Believeth on Me, but on Him that sent Me. Why is one to hear His word, and believe another? Is it not that He means to say, His word is in Me? And what is, Heareth My word, but heareth Me? And it is, Believeth on Him that sent Me; as to say, He that believeth on Him, believeth on His Word, i. e. on Me, because I am the Word of the Father.
