As long as there are 2 variables, you can not draw (or fade) a conclusion (e.g. why is Tiger Woods not doing well at the 2014 PGA Championship? Is it because of his recent back surgery or has he changed his swing?)
Thus, the Church is remiss in acknowledging Paul as the apostle to the Gentiles. The Church has placed all her eggs in one basket. Do we have 1 Gospel or four? Do we have 1 synoptic Gospel or 3? How many writings of Paul are in the New Testament vs. Peter?
We know that God, Jehovah, confirms his will with confirmation in 3s.
Samuel was called by God 3 times until Eli recognized it was God calling Samuel.
Peter denied Jesus 3 times before the cock crowed.
Jesus was 3 days and 3 nights in the heart of the earth.
Peter saw a vision of a sheet going up and down [3 times] full of unclean and common(e.g. those clean touching the unclean making them common - a manmade distinction)
God knew Gentiles were clean, not common, as Peter assumed.
God hates manmade distinctions. The Pharisees were great at manmade distinctions.
After seeing the Holy Spirit fall on Cornelius and his group, Peter was estatic!
He knew then that God made no distinctions, and that all men were clean before God because of Jesus. God wanted Peter to know it was okay to go to the house of Cornelius and associate with him, a gentile. Jews would not do such things.
As for Paul, we do not see God confirming in 3s during the story of Paul and his vision on the road to Damascus. That could be highly significant. We also know that Paul was not with Jesus in the flesh from Baptism through Resurrection and Ascension. Matthias who replaced Judas was. These are significant facts to consider when asking was Peter or Paul the man ordained by God to the Gentiles.
