Jamieson, Fausset & Brown

honour the Son as . . . the Father--As he who believes that Christ in the foregoing verses has given a true account of His relation to the Father must of necessity hold Him entitled to the same honor as the Father, so He here adds that it was the Father's express intention in making over all judgment to the Son, that men should thus honor Him. honoureth not the Father--does not do it in fact, whatever he may imagine, and will be held as not doing it by the Father Himself, who will accept no homage which is not accorded to His own Son.
