I challenge you to show me in scripture where Paul revealed a mystery that was given to him and not the other Apostles.
I'll play the first card. Paul said that God made known the mystery to him by revelation, but he said it is the same mystery that "is now revealed unto his holy apostles and prophets by the Spirit".
Ephesians 3:3-6
How that by revelation he made known unto me the mystery; (as I wrote afore in few words, Whereby, when ye read, ye may understand my knowledge in the mystery of Christ) Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit; That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel:
That same mystery, at that same time, was being revealed to the other Apostles and prophets, by the same Spirit.
It makes sense then that Peter went to the Gentiles, and God filled them with the Holy Ghost by FAITH, and without the works of the law... before Paul got his revelation.
