It is interesting though that Jesus ostensibly taught us to pray "Our Father..." which is a genuinely structured Hebrew prayer, making no reference to anything outside Old Testament standards.
An interesting work in this regard is Hyam Macoby, Revolution in Judea: Jesus and the Jewish Resistance (1973)
Regardless of whether or not you believe Paul supernaturalized Jesus, the tomb was still empty on the First Easter. The empty tomb was one of the primary reasons why Paul did supernaturalize Jesus because it was proof of his resurrection. John’s gospel, though written later than even Paul, is full of Jesus statements asserting his deity. The deity of Christ is strongly implied in the synoptic gospels - and the title “Son of Man” is a divine Messianic title taken from Daniel 7 in the Old Testament.
