He had to be. Peter didn't save him, or cause him to be saved. Peter just witnessed Cornelius and his household receive the gifts of the Holy Spirit.Was God pleased with Cornelius
Acts 10:1-4 (KJV)
1 There was a certain man in Caesarea called Cornelius, a centurion of the band called the Italian band,
2 A devout man, and one that feared God with all his house, which gave much alms to the people, and prayed to God alway.
3 He saw in a vision evidently about the ninth hour of the day an angel of God coming in to him, and saying unto him, Cornelius.
4 And when he looked on him, he was afraid, and said, What is it, Lord? And he said unto him, Thy prayers and thine alms are come up for a memorial before God.
So was God pleased with Cornelius
Was he a saved man before his meeting with Peter ?
