The vows are words which carry tremendous weight and serve as a powerful testimony of a heart turned (turning) to Christ. It is a formula leading to new life in Christ.
If you are outside the fold of Christ, the Good Shepherd, these are words which, when spoken—even silently—from the heart, will start you on a journey to Jesus, the God-Man and Saviour of the world.
I, [your name], who through the tender mercy of the Eternal Father was privileged to be baptized "in the name of the Lord Jesus" (Acts 19, 5) and thus to share in the dignity of his divine Sonship, wish now in the presence of this same loving Father and of his only-begotten Son to renew in all sincerity the promises I solemnly made at the time of my holy Baptism.
I, therefore, now do once again renounce Satan; I renounce all his works; I renounce all his allurements.
I believe in God, the Father Almighty, Creator of heaven and earth. I believe in Jesus Christ, his only Son, our Lord, who was born into this world and who suffered and died for my sins and rose again. I believe in the Holy Spirit, the Holy Catholic Church, the communion of Saints, the forgiveness of sins, the resurrection of the body and life everlasting.
Having been buried with Christ unto death and raised up with him unto a new life, I promise to live no longer for myself or for that world which is the enemy of God but for him who died for me and rose again, serving God, my heavenly Father, faithfully and unto death in the holy Catholic Church.
Taught by our Savior's command and formed by the word of God, I now dare to say:
Our Father, who art in heaven, hallowed be thy name; thy kingdom come; thy will be done on earth as it is in heaven. Give us this day our daily bread; and forgive us our trespasses as we forgive those who trespass against us; and lead us not into temptation, but deliver us from evil.
If you prayed this prayer for the first time and would like to follow the Lord Jesus Christ in baptism, please visit a Catholic Church and meet with the priest who will guide you further.
May God bless you and keep you faithful to our Lord Jesus Christ for ever and ever.
