According to the Acts of the Apostles (10:45) the first pagan converted to Christ was an officer of the imperial Roman army. Cornelius the Centurion is described by the scriptures as a devout man who feared God, gave alms generously, and prayed constantly to God (10:1-2).
Cornelius and the Apostle Peter had simultaneous visions that eventually brought them together (10:5; 10:15) at Cornelius’ house and in the presence of Cornelius’ whole household. Peter assured Cornelius that God shows no partiality and briefly related the history of Jesus’ preaching and death. At this, the Holy Spirit was poured out on all who were listening, Jew, and Gentile alike. Peter was so astounded that the Spirit was given to the pagans as well as the Jews that he readily acceded to Cornelius’ request for baptism for himself and his entire household.
When some of the Jewish Christians back in Jerusalem learned of what had happened, they criticized Peter severely. Later a Council had to be convened, headed by James to settle the dispute (Acts 15). Peter was vindicated, and a new missionary outreach to the Gentiles was inaugurated. Cornelius’ feast day is February 4.
