A small number of liberal biblical scholars have recently tried to prove that Matthew, Mark, and Luke never believed Jesus was God.
This careful, thorough book by Gathercole proves them wrong.
Since the early 1900's when the old 'History of Religions' theory was in bloom, scholars such as Bousset "argued...that the titles...'Son of Man' and 'Lord' had their origins in Hellenistic mystery religions" p 3). These ideas were so soundly refuted that "it is largely in reaction" (p 3) Gathercole argues that some scholars now insist there is "no preexistence christology in the Synoptic gospels (p 3).
Gathercole calls such scholars as Bauckham and Hurtado the 'New History of Religions School'. They are scholars who have intensively studied the effects of Second Temple Judaism upon early Christianity; not, of course, the mystery religions. Hurtado especially is known for claiming that Paul shows high Christology throughout his epistles.
Gathercole argues that in the epistles he can show belief in Christ's preexistence from the start of Christianity and certainly before 70 AD. "Philippians 2 "constitutes the highest Christological reflection in the NT" (p 24). In the hymn Christ is said to be God but who took on the form of a servant--as a man--and humbled himself by dying on the cross. There are also instances in 1 Corinthians 15.47 and Romans 10.6 showing preexistence. These and other references show belief in preexistence in AD 48 and onwards.
"Jesus is portrayed in the Synoptic Gospels as having a heavenly identity...before Easter" (p 54) in the transfiguration and elsewhere. Also, Jesus forgives sin which his critics point out, can only be done by God. In Matthew, Jesus controls the weather, can walk on water, and those in the boat "worshiped him". He controls demons and can read minds. All of which proves Jesus was God, according to the Synoptics.
In addition to forgiving sins, Jesus also tells his apostles that "Whatever you bind on earth will be bound in heaven", also pointing to divine authority.
Gathercole also discusses the "I have come" sayings of Jesus, which, he points out, "are summaries of Jesus' mission as a whole" (p 85). Again and again Jesus makes references to the fact that he came for specific purposes. To preach, to cast fire on earth, to bring division between people--these are a few of the instances. Also, Jesus says that he wanted to father "your children together as a hen gathers her brood under her wings" and this "metaphor requires a heavenly, indeed, a divine being" (p 211).
Christ is also given a number of titles throughout the Snoptics, such as "Lord" "Christ", "Son of Man" and "Son of God". Gathercole follows Martin Hengel in arguing that in a number of places " the 'Son of Man' is identified with the Messiah" (p 232).
Anyone who wants to argue that early Christianity did not believe Jesus was divine will have to deal with the arguments in this book first.
