and Jesus also promised that those who call on HIS name shall be saved. And Jesus also said Go and baptize everyone in the name of The Father, and of the Son, and of the Holy Spirit. Did Peter change that? No, he did not.There is an absolute promise in holy scripture, that if one repents and is baptized in the name of Jesus Christ for the remission of sins, salvation (remission of sins and the gift of the Holy Ghost) will follow (Acts 2:38-39).
