Did Jesus minister to Gentiles during His earthly ministry?

No, Jesus did not minister to Gentiles during His earthly ministry, with only one or two exceptions. The scriptural record does not show Him having any concert with Gentiles, and attempts to find such ministry are not supported by the text.

Les explains that people get shook up when he says Jesus never ministered to Gentiles during His earthly ministry, with one or two exceptions. They try to find all kinds of excuses that He must have gone to Gentiles, but he challenges them to show him in Scripture where Jesus had any concert with Gentiles. This fits the context of Ananias being told that Saul of Tarsus is a chosen vessel to bear Jesus' name before the Gentiles, indicating a later ministry to Gentiles.

Were there any Gentiles Jesus ministered to?

Yes, but only as exceptions: the Roman Centurion and the woman of Canaan. Apart from those, His ministry was confined to the Jews in the land between the Jordan and the Mediterranean, and He told the twelve not to go to Gentiles or Samaritans.
