The Vatican Council
PROFESSION OF FAITH - January 6th, 1870
I, Pius, bishop of the catholic church, with firm faith believe and profess each and every article contained in the profession of faith which the holy Roman church uses, namely:
I believe in one God the Father almighty, maker of heaven and earth, of all things seen and unseen. And in one Lord Jesus Christ the only-begotten Son of God. Born of the Father before all ages. God from God, light from light, true God from true God. Begotten not made, of one substance with the Father: through whom all things were made. Who for us humans and for our salvation came down from heaven. He was incarnate by the Holy Spirit of the virgin Mary: and became man. He was crucified also for us, he suffered under Pontius Pilate and was buried. The third day he rose again according to the scriptures. He ascended into heaven and sits at the right hand of the Father. He shall come again with glory to judge the living and the dead, and of his kingdom there shall be no end. And in the Holy Spirit, the lord and the giver of life, who proceeds from the Father and the Son. Who together with the Father and the Son is adored and glorified: who spoke through the prophets. And one holy, catholic and apostolic church. I confess one baptism for the remission of Sins. And I look for the resurrection of the dead. And the life of the world to come Amen.
Apostolic and ecclesiastical traditions and all other observances and constitutions of that same church I most firmly accept and embrace. Likewise I accept sacred scripture according to that sense which holy mother church held and holds, since it is her right to judge of the true sense and interpretation of the holy scriptures; nor will I ever receive and interpret them except according to the unanimous consent of the fathers.
I profess also that there are seven sacraments of the new law, truly and properly so called, instituted by our lord Jesus Christ and necessary for salvation, though each person need not receive them all. They are: baptism, confirmation, the Eucharist, penance, last anointing, order and matrimony; and they confer grace. Of these baptism, confirmation and order may not be repeated without sacrilege. I likewise receive and accept the rites of the catholic church which have been received and approved in the solemn administration of all the aforesaid sacraments. I embrace and accept the whole and every part of what was defined and declared by the holy council of Trent concerning original sin and justification. Likewise I profess that in the mass there is offered to God a true, proper and propitiatory sacrifice for the living and the dead; and that in the most holy sacrament of the Eucharist there is truly, really and substantially the body and blood, together with the soul and divinity, of our lord Jesus Christ; and that there takes place the conversion of the whole substance of the bread into his body, and of the whole substance of the wine into his blood, and this conversion the catholic church calls transubstantiation. I confess that under either species alone the whole and complete Christ and the true sacrament are received.
I firmly hold that purgatory exists, and that the souls detained there are helped by the suffrages of the faithful. Likewise, that the saints reigning with Christ are to be honoured and prayed to, and that they offer prayers to God on our behalf, and that their relics should be venerated. I resolutely assert that images of Christ and the ever virgin mother of God, and likewise those of the other saints, are to be kept and retained, and that due honour and reverence is to be shown them. I affirm that the power of indulgences was left by Christ in the church, and that their use is eminently beneficial to the christian people.
I acknowledge the holy, catholic, apostolic and Roman church, the mother and mistress of all the churches  . Likewise all other things which have been transmitted, defined and declared by the sacred canons and the ecumenical councils, especially the sacred Trent, I accept unhesitatingly and profess; in the same way whatever is to the contrary, and whatever heresies have been condemned, rejected and anathematised by the church, I too condemn, reject and anathematise. This true catholic faith, outside of which none can be saved, which I now freely profess and truly hold, is what I shall steadfastly maintain and confess, by the help of God, in all its completeness and purity until my dying breath, and I shall do my best to ensure  that all others do the same. This is what I, the same Pius, promise, vow and swear. So help me God and these holy gospels of God.
1. The profession of faith of the other fathers added: and I pledge and swear true obedience to the Roman pontiff, successor of blessed Peter the prince of the apostles, and vicar of Jesus Christ
2. The profession of faith of the other fathers continues: my subjects, or those for whom I have responsibility in virtue of my office, hold, teach and preach the same.
