Credo in Deum Patrem omnipotentem;
Creatorem caeli et terrae.
Et in Jesum Christum,
Filium eius unicum, Dominum nostrum;
qui conceptus est
de Spiritu Sancto,
natus ex Maria virgine;
passus sub Pontio Pilato,
crucifixus, mortuus, et sepultus;
descendit ad inferos;
tertia die resurrexit a mortuis;
ascendit ad caelos;
sedet ad dexteram Dei Patris omnipotentis;
inde venturus est
iudicare vivos et mortuos.
Credo in Spiritum Sanctum;
sanctam ecclesiam catholicam;
sanctorum communionem;
remissionem peccatorum;
carnis resurrectionem;
vitam aeternam. Amen.
In English:
I believe in God, the Father almighty,
creator of heaven and earth.
I believe in Jesus Christ,
his only Son, our Lord.
He was conceived
by the power of the Holy Spirit,
and born of the Virgin Mary,
He suffered under Pontius Pilate,
was crucified, died, and was buried;
He descended into hell.
On the third day he rose again;
he ascended into heaven,
he is seated at the right hand of the Father,
he will come again
to judge the living and the dead.
I believe in the Holy Spirit,
the holy Catholic church,
the communion of saints,
the forgiveness of sins,
the resurrection of the body,
and the life everlasting. Amen

A General Rule for distinguishing the Truth of the Catholic Faith from the Falsehood of Heretical Pravity.
[4.] I have often then inquired earnestly and attentively of very many men eminent for sanctity and learning, how and by what sure and so to speak universal rule I may be able to distinguish the truth of Catholic faith from the falsehood of heretical pravity; and I have always, and in almost every instance, received an answer to this effect: That whether I or any one else should wish to detect the frauds and avoid the snares of heretics as they rise, and to continue sound and complete in the Catholic faith, we must, the Lord helping, fortify our own belief in two ways; first, by the authority of the Divine Law, and then, by the Tradition of the Catholic Church.
[5.]
But here some one perhaps will ask, Since the canon of Scripture is complete, and sufficient of itself for everything, and more than sufficient, what need is there to join with it the authority of the Church's interpretation? For this reason—because, owing to the depth of Holy Scripture, all do not accept it in one and the same sense, but one understands its words in one way, another in another; so that it seems to be capable of as many interpretations as there are interpreters. For Novatian expounds it one way, Sabellius another, Donatus another, Arius, Eunomius, Macedonius, another, Photinus, Apollinaris, Priscillian, another, Iovinian, Pelagius, Celestius, another, lastly, Nestorius another. Therefore, it is very necessary, on account of so great intricacies of such various error, that the rule for the right understanding of the prophets and apostles should be framed in accordance with the standard of Ecclesiastical and Catholic interpretation.
[6.] Moreover, in the Catholic Church itself,
all possible care must be taken, that we hold that faith which has been believed everywhere, always, by all. For that is truly and in the strictest sense Catholic, which, as the name itself and the reason of the thing declare, comprehends all universally. This rule we shall observe if we follow universality, antiquity, consent. We shall follow universality if we confess that one faith to be true, which the whole Church throughout the world confesses; antiquity, if we in no wise depart from those interpretations which it is manifest were notoriously held by our holy ancestors and fathers; consent, in like manner, if in antiquity itself we adhere to the consentient definitions and determinations of all, or at the least of almost all priests and doctors.
Chapter 3.
What is to be done if one or more dissent from the rest.
[7.] What then will a Catholic Christian do, if a small portion of the Church have cut itself off from the communion of the universal faith? What, surely, but prefer the soundness of the whole body to the unsoundness of a pestilent and corrupt member? What, if some novel contagion seek to infect not merely an insignificant portion of the Church, but the whole? Then it will be his care to cleave to antiquity, which at this day cannot possibly be seduced by any fraud of novelty.
[8.] But what, if in antiquity itself there be found error on the part of two or three men, or at any rate of a city or even of a province? Then it will be his care by all means, to prefer the decrees, if such there be, of an ancient General Council to the rashness and ignorance of a few. But what, if some error should spring up on which no such decree is found to bear? Then he must collate and consult and interrogate the opinions of the ancients, of those, namely, who, though living in various times and places, yet continuing in the communion and faith of the one Catholic Church, stand forth acknowledged and approved authorities: and whatsoever he shall ascertain to have been held, written, taught, not by one or two of these only, but by all, equally, with one consent, openly, frequently, persistently, that he must understand that he himself also is to believe without any doubt or hesitation.

How Heretics, craftily cite obscure passages in ancient writers in support of their own novelties. [19.] This condemnation, indeed, seems to have been providentially promulgated as though with a special view to the fraud of those who, contriving to dress up a heresy under a name other than its own, get hold often of the works of some ancient writer, not very clearly expressed, which, owing to the very obscurity of their own doctrine, have the appearance of agreeing with it, so that they get the credit of being neither the first nor the only persons who have held it. This wickedness of theirs, in my judgment, is doubly hateful: first, because they are not afraid to invite others to drink of the poison of heresy; and secondly, because with profane breath, as though fanning smouldering embers into flame, they blow upon the memory of each holy man, and spread an evil report of what ought to be buried in silence by bringing it again under notice
