Augustine of Hippo — as excerpted in the Catena Aurea on John 14:5-7

“(de Verb. Dom. s. liv) As if He said, I am the way, whereby thou wouldest go; I am the truth, whereto thou wouldest go; I am the life, in which thou wouldest abide. The truth and the life every one understands (capit); but not every one hath found the way. Even the philosophers of the world have seen that God is the life eternal, the truth which is the end of all knowledge. And the Word of God, which is truth and life with the Father, by taking upon Him human nature, is made the way. Walk by the Man, and thou wilt arrive at God. For it is better to limp on the right way, than to walk ever so stoutly by the wrong.”
