Here:
Did the living Jesus recorded in the New Testament believe that his mission extended to gentiles? None of the four canonical Gospels explicitly declare that he recognized any duty beyond the frontiers of Judaism, which is remarkable when we recall that all four were written at a time when the Jesus movement had opened its doors to non-Jews.
----------------------------------------
Jenkins cites evidence, but not of the starkest sort which explicitly forbids the Gentile mission:
"Into the way of the Gentiles do not go . . .."
-- Matthew 10:5
Liberal Bishop John A. T. Robinson in 1976 famously put the composition of most of the New Testament before 70 A.D. for the failure to even hint at the destruction of the temple, which would mean that the absence of a Gentile mission sensibility in the gospels isn't an oddity but a marker equal in significance for an earlier dating of the gospel sources. That said, the tyranny of the Passion narrative in the Synoptics speaks to the intrusion of an editorial impulse from the later period which must not be quickly discounted, nor naively accepted (e.g. from the supplied ending to Mark, Mark 16:15: "And he said unto them, Go ye into all the world, and preach the gospel to every creature").
