Note that the following profession of faith, intended for Protestant converts to Catholicism and published early in the 20th century, has a strong emphasis on obedience to presumed Roman ecclesiastical authority, and claims that salvation comes through sacraments administered by the Church, but actually says nothing about repenting of sin, or professing a saving faith in Jesus Christ's atoning death for those sins.

RECEPTION OF A CONVERT

A. THE PROFESSION OF FAITH.

    I, ........., having before my eyes the holy Gospels, which I touch with my hands, and knowing that no one can be saved without that Faith which the Holy Catholic Apostolic Roman Church holds, believes, and teaches, against which I agree that I have greatly erred, in as much as I have held and believed doctrines opposed to her teaching.
    I now, with grief and contrition for my past errors, profess that I believe the Holy, Catholic, Apostolic, Roman Church to be the only and true Church established on earth by Jesus Christ, to which I submit myself with my whole heart. I believe all the articles that she proposes to my belief, and I reject and condemn all that she rejects and condemns, and I am ready to observe all that she commands me. And especially I profess that I believe: One only God in three divine Persons, distinct from and equal to each other,—that is to say, the Father, the Son, and the Holy Ghost: The Catholic Doctrine of the Incarnation, Passion, Death and resurrection of our Lord Jesus Christ; and the personal union of the two Natures, the divine and the human; the divine Maternity of the most holy Mary, together with her most spotless Virginity;
   The true, real and substantial presence of the body and blood, together with the Soul and Divinity of our Lord Jesus Christ, in the most holy Sacrament of the Eucharist; [pg. 102]
    The seven Sacraments instituted by Jesus Christ for the salvation of mankind; that is to say, Baptism, Confirmation, Eucharist, Penance, Extreme Unction, Order, Matrimony;
    Purgatory, the Resurrection of the dead, Everlasting life;
    The Primacy, not only of honor, but also of jurisdiction of the Roman Pontiff, successor of St. Peter, Prince of the Apostles, Vicar of Jesus Christ; the veneration of the Saints and of their images; The authority of the Apostolic and Ecclesiastical traditions, and of the Holy Scriptures, which we must interpret and understand only in the same sense which our holy Mother the Catholic Church has held and does hold; And everything else that has been defined and declared by the Sacred Canons and by the General Councils, and particularly by the Holy Council of Trent, and delivered, defined and declared by the General Council of the Vatican, especially concerning the Primacy of the Roman Pontiff and his Infallible teaching authority.
    With a sincere heart, therefore, and with unfeigned faith, I detest and abjure every error, heresy and sect opposed to the said Holy Catholic and Apostolic Roman Church. So help me God and these Gospels, which I touch with my hand.
