No his soul was saved by entering into a relationship with God through Jesus Christ. Baptism is only part of the process.
Catholic Baptism takes away sins and makes one a member of Christ's Mystical Body. Paul revealed the essential effect of baptism when he wrote to the Galatians: "All of you who have been baptized into Christ have clothed yourselves with him" (3:27). Paul's reflection is linked to the doctrine transmitted by John's Gospel, especially to Jesus' conversation with Nicodemus: "Unless one is born of water and the Spirit, he cannot enter the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit" (3:5-6). The Holy Spirit brings about the birth and growth of a divine, "spiritual" life in Christians. This life animates and elevates their being. Through the Spirit, the very life of Christ bears its fruit in Christian existence.
Catholics, through the Sacrament of Baptism, have a 'relationship' with God as members of His mystical Body.
