Cornelius the Centurion was a Roman officer mentioned in the New Testament of the Bible, specifically in the Book of Acts. He is known for being the first Gentile to convert to Christianity, marking a significant moment in the early church's expansion beyond Jewish communities. Cornelius lived in Caesarea, a coastal city in ancient Judea. He was described as a devout man who feared God and was generous to the poor. His story highlights the importance of faith and obedience, as he received a vision that led him to seek out the Apostle Peter, who baptized him and his household.
