to quote Richard Church; \"after the start of the dispensation of grace in Acts 9, God did begin to give these gifts to the Gentiles as a sign to Israel that He was doing something new. This is exactly what Peter testifies in Acts 15 regarding the giving of the gift of tongues to the household of Cornelius. \" Peter is talkin about tongues(the signs)and giving that new gospel to the house of cornelius as we read about in Acts 10. Cornelius obviously is a gentile. Acts 15 and Galatians 2 is the same event. we obviously know from galatians 2 that peter went to the circumcision.
