Scripture does not support the idea that Paul preached a different gospel. Rather, it reveals he preached the same gospel as the other apostles while further revealing the mysteries and spiritual significance behind the essential elements of the NT rebirth.
Peter, on the Day of Pentecost, commanded believers to repent, be baptized in the name of Jesus Christ for the remission of sins, and receive the gift of the Holy Ghost (Acts 2:38). Paul preached that same message. (Acts 16:31-33; 19:1-6). He also publicly testified that Ananias instructed him, "Arise, and be baptized, and wash away thy sins, calling on the name of the Lord" (Acts 22:16). This was not merely Luke's account of Paul's conversion—it was Paul's own testimony before a hostile Jewish audience in Jerusalem decades after the event. (Acts 22) If Paul believed water baptism had no connection to the remission of sins, this would have been the perfect opportunity to clarify or qualify Ananias' words. Instead, he repeated them without alteration, affirming that obedience to this command was when his sins were washed away. His testimony is in complete harmony with Peter's command on the Day of Pentecost.
What distinguishes Paul's writings is not a different gospel, but the additional revelation Christ gave him concerning the meaning of these commands. For example, Paul explains that in water baptism believers are buried with Christ into His death and raised to walk in newness of life (Rom. 6:3-4; Col. 2:12). He reveals believers are baptized into one body by one Spirit, are washed, sanctified, and justified in the name of the Lord Jesus and by the Spirit of God (1 Cor. 6:11), and are sealed with the Holy Ghost of promise after hearing the word of truth. (Acts 19: 1-7, Eph. 1:13).
Paul himself denied preaching a different gospel. He declared, "Whether therefore it were I or they, so we preach, and so ye believed" (1 Cor. 15:11). Likewise, he warned that "though we, or an angel from heaven, preach any other gospel unto you than that which WE have preached unto you, let him be accursed" (Gal. 1:8). His message was in complete harmony with the other apostles. Jesus entrusted Paul with further revelation that unfolded the depth and significance of the essential elements of the NT rebirth experienced by all believers.
