<p>5:5- see on Rom. 8:26.</p><p><i>So Christ also did not glorify himself to become a high priest, but He that spoke to him: You are my Son. This day have I begotten you</i>- The calling to be high priest was through His resurrection, which was when He was declared God's Son in power (Rom. 1:4). There is no record of the Father ever speaking these words to the Son; perhaps they were spoken in some intimate ceremony at or after the resurrection or ascension. The new kind of high priesthood in view is predicated upon sonship- but not of Aaron, but of God. God's Son was therefore high priest, on account of His begettal from the dead in resurrection. It was this which qualified Him to be High Priest, having been subject to human weakness (:2) and also to glory and power over that weakness.</p>
