In the Gospel reading for this last Sunday the Man Christ Jesus was walking on the water based on His own Personal divine Power.  We also saw the man Peter walking on the water based on the Word of Christ inviting him:  "come."  This Gospel reading was paired with Job 9 as the Old Testament reading, a reading which emphasizes that God tramples the waves.  When paired with the Matthew 14 account of the Man Jesus walking upon the waves of the Sea of Galilee we realize that the Scriptures (and that action of Christ) are declaring Him to be God.  In the "Treasury of Daily Prayer" published by CPH the Matthew 14 account of Jesus' walk upon the sea is paired with Deuteronomy 18, wherein Moses tells the people of Israel that God will raise up a prophet "like me" from among your own brothers, to Him you are to listen.

Moses was a rescuer in the Exodus (having been rescued in his infancy).  Moses was a leader through the sea and the wilderness (having been led with his first-rate education and his instruction from God).  However, we might know Moses best as a prophet and author.  He wrote the first five books of the Scriptures.  His role as prophet comes out most clearly in Deuteronomy 18, considered above.  There were many true prophets after Moses (Samuel, David, Elijah, Isaiah, Daniel, etc.), whose writings are based on his and who both taught and wrote.

Jesus is "the Prophet" Moses spoke of in Deuteronomy 18.  Jesus also fulfills all of the prophecies written down in the Scriptures of Israel.  Jesus gave prophecies of His own that He then fulfilled, particularly having to do with His death and resurrection (Matthew 16:21f.; 17:12, 22f.; 20:17f.; 26:2--note also the proclamation of the angel, confirming Jesus' own Word and Jesus' resurrection, in Matthew 28:6--"He is not here, for He has been raised, just as He said").  

Jesus is a unique prophet.  He confirmed His words and teaching with miracles and signs, like feeding the 5,000, walking on water, and--especially--rising from the dead.  He was not an author...in the sense of writing down Scripture.  Most religions have (false) prophets who also gave "sacred writings":  the Book of Mormon, the Koran, the sutras (the Buddha never wrote anything, but his teachings were written down hundreds of years after his death).

Jesus never wrote anything but He nevertheless is an author in the truest and fullest sense, and in a way that transcends all prophets (whether true or false).  An author is "the source" of something.  Jesus is called "the Author of life" by Peter in one of his early sermons (Acts 3:15), the Author of life Whom the Jews had crucified.  The writer of Hebrews says that the "Author of our salvation" was made perfect through suffering.  Jesus is the author of Baptism and the Lord's Supper.  These means of grace that bring the salvation Jesus earned "for us" now "to us" are based on His author-ity as the Son of God.  No man can institute a sacrament, Jesus has.  As author of baptism Jesus has undergone it--including His own death and resurrection--and in instituting it reveals the Triune God (see Matthew 28:19-20).  As author of His holy Supper Jesus gives the official preaching and interpretation of His death and its meaning, and promises living food for sinners in that Sacrament.  This Sacrament is the Last Will and Testament of the Son of God.  

As author of Baptism and the holy Lord's Supper Jesus doesn't put pen to paper.  Rather, these find their souce in Him as their origin from His very Body upon the cross.  There the soldier pierced Him to make sure He was dead, but right there Jesus is the source of forgiveness, life, and salvation as the water (baptism) and the blood (the holy communion) flow forth from His sacrificial body (see John 19:34).  Jesus is the Alpha and the Omega, the author of our salvation, and the source of the precious means of grace.
