Well surely then you can explain what the context of these verses is...
Gal 2:7 But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter;
Gal 2:8 (For he that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles:)
Do you ACTUALLY think that a case where a Jew/Gentile was hearing Paul/Peter preach and at the end goes up to the teacher and says "Master, I believe and want to be baptized" that Paul/Peter would say "Sorry, Charlie, but you've got to wait until Peter/Paul shows up before you can be join the Church". The idea is simply laughable.
