You quoted Matthew. Show where Christ confirms Matthew as Apostle to you & I. Simple verses will prove your point. Christ teaches that Paul is Apostle to the Gentiles - you & I The other Apostles confirm Paul is Apostle to the Gentiles - you & I. The other Apostles confirm their role is to the UNcircumcision. Paul teaches how you & I are saved. They (12) are PROPHECY.Paul is MYSTERY. Paul role was UNKNOWN prior to Acts 9:10-15 Eventually the 12 Apostles realized & confirmed Paul's role eg Gal 2:7-9. There is nothing hard about it. The hard part is the confusion caused when mixing what Paul taught with the other 12.
