I [name and surname], Cardinal of the Holy Roman Church, promise and swear to be faithful henceforth and forever, while I live, to Christ and his Gospel, being constantly obedient to the Holy Roman Apostolic Church, to Blessed Peter in the person of the Supreme Pontiff John Paul II, and of his canonically elected Successors; to maintain communion with the Catholic Church always, in word and deed; not to reveal to any one what is confided to me in secret, nor to divulge what may bring harm or dishonor to Holy Church; to carry out with great diligence and faithfulness those tasks to which I am called by my service to the Church, in accord with the norms of the law.
So help me Almighty God.
