St. Paul calls himself the slave of Jesus Christ. Even though the Apostle Paul was a Roman citizen and had studied under the best rabbis in Jerusalem, he was humble with all his learning and position. Paul saw that since Jesus’ blood had ransomed him (purchased his soul from evil), he no longer belonged to himself but to Jesus, and now wanted to live his life completely for Him and in His service.
1 Paul, a slave of Christ Jesus, called to be an apostle and set apart for the gospel of God, 2 which he promised previously through his prophets in the holy Scriptures, 3 the Gospel about his Son, descended from David according to the flesh, 4 but established as Son of God in power according to the spirit of holiness through resurrection from the dead, Jesus Christ our Lord. 5 Through him we have received the grace of apostleship, to bring about the obedience of faith, for the sake of his name, among all the Gentiles, 6 among whom are you also, who are called to belong to Jesus Christ; 7 to all the beloved of God in Rome, called to be holy. Grace to you and peace from God our Father and the Lord Jesus Christ.
