Denzinger, Enchiridion Symbolorum (11th ed., 1911)

“Canon 1. Following the example of the holy Fathers, and renewing what the duty of our office requires, we forbid absolutely, by the authority of the Apostolic See, that anyone be ordained or promoted for money in the Church of God. If anyone has obtained ordination or promotion in the Church in such a way, let him lose his rank altogether. Canon 3. We wholly forbid priests, deacons and subdeacons the company of concubines and wives, and cohabitation with any other women, save those whom the Council of Nicaea permitted to dwell with them for reasons of necessity alone — namely a mother, a sister, a paternal aunt, a maternal aunt, or others of that kind.”

“Canon 2. If anyone has obtained by money — the accursed heat of avarice intervening — a prebend, or a priorship, or a deanery, or any ecclesiastical honour or promotion, or any ecclesiastical sacrament whatever, such as chrism or holy oil or the consecration of altars or of churches, let him lose the honour thus ill gotten; and let the buyer, the seller and the go-between be struck with the mark of infamy. And let nothing be demanded of anyone by anybody, either beforehand or afterwards, whether for a meal or under pretext of any custom, nor let him presume to give anything, since that is simoniacal; but let him enjoy freely and without any diminution the dignity and benefice conferred upon him.”

“Chapter 27. As blessed Leo says, although the discipline of the Church, content with the judgement of a priest, does not carry out bloody punishments, it is nevertheless assisted by the enactments of catholic princes, so that men often seek a salutary remedy while they fear that bodily punishment will come upon them. Therefore, since in Gascony, in the Albigensian territory, in the region of Toulouse and in other places the condemned perversity of the heretics — whom some call Cathars, others Patarenes, others Publicani, others by other names — has so far prevailed that they no longer practise their wickedness in secret, as some do, but make their error known publicly and draw the simple and the weak into agreement with them: we decree that they, and those who defend and harbour them, lie under anathema; and under anathema we forbid anyone to presume to keep or foster them in his houses or on his land, or to carry on trade with them.”

“We firmly believe and simply confess that there is one only true God, eternal, immeasurable and unchangeable, incomprehensible, almighty and ineffable, Father and Son and Holy Spirit: three Persons indeed, but one essence, substance or nature altogether simple. The Father from none, the Son from the Father alone, and the Holy Spirit equally from both: without beginning, always and without end; the Father begetting, the Son being born, and the Holy Spirit proceeding; consubstantial and coequal and coalmighty and coeternal; one principle of all things; creator of all things visible and invisible, spiritual and corporeal; who by his almighty power from the beginning of time made together out of nothing both orders of creature, the spiritual and the corporeal, that is the angelic and the earthly, and thereafter the human, as it were common to both, composed of spirit and body. For the devil and the other demons were indeed created by God good in their nature, but they made themselves evil of their own doing. Man however sinned at the suggestion of the devil. This Holy Trinity, undivided according to its common essence and distinct according to the properties of the Persons, gave to the human race the doctrine of salvation, first through Moses and the holy Prophets and his other servants, according to the most orderly disposition of the times. And at the last the only-begotten Son of God, Jesus Christ, made flesh by the whole Trinity in common, conceived of Mary ever Virgin by the co-operation of the Holy Spirit, made true man, composed of a rational soul and human flesh, one Person in two natures, showed more plainly the way of life. Who, although according to his divinity he is immortal and impassible, the same according to his humanity was made passible and mortal; who also, for the salvation of the human race, having suffered and died upon the wood of the cross, descended to the realms below, rose again from the dead and ascended into heaven — but he descended in the soul and rose again in the flesh, and ascended alike in both — to come at the end of the world, to judge the living and the dead, and to render to each according to his works, to the reprobate as to the elect: who shall all rise again with their own bodies, which they now bear, that they may receive according to their works, whether these have been good or evil; the one everlasting punishment with the devil, and the other everlasting glory with Christ. There is moreover one universal Church of the faithful, outside which no one at all is saved; in which Jesus Christ himself is both priest and sacrifice, whose body and blood are truly contained in the sacrament of the altar under the species of bread and wine, the bread having been transubstantiated into the body and the wine into the blood by divine power, so that, to accomplish the mystery of unity, we ourselves may receive of what is his what he himself received of what is ours. And this sacrament no one at all can confect but a priest who has been rightly ordained according to the keys of the Church, which Jesus Christ himself granted to the Apostles and their successors. But the sacrament of baptism — which is consecrated in water at the invocation of God and the undivided Trinity, namely of the Father and of the Son and of the Holy Spirit — rightly conferred by anyone in the form of the Church, profits unto salvation both little ones and adults. And if anyone, after receiving baptism, has fallen into sin, he can always be restored through true penance. Moreover not only virgins and the continent, but also the married, pleasing God by right faith and good works, deserve to come to eternal blessedness.”

“With faithful and devout profession we confess that the Holy Spirit proceeds eternally from the Father and the Son, not as from two principles but as from one principle, not by two spirations but by a single spiration. This the most holy Roman Church, mother and teacher of all the faithful, has professed, preached and taught until now; this she firmly holds, preaches, professes and teaches. This is the unchangeable and true judgement of the orthodox Fathers and Doctors, Latin and Greek alike. But because some, through ignorance of the aforesaid irrefutable truth, have fallen into various errors, we, desiring to bar the way to errors of this kind, with the approval of the sacred Council condemn and reprove those who shall presume to deny that the Holy Spirit proceeds eternally from the Father and the Son, or who with rash daring shall assert that the Holy Spirit proceeds from the Father and the Son as from two principles and not as from one.”

“Furthermore, every doctrine or proposition rashly asserting, or calling into doubt, that the substance of the rational or intellective soul is not truly and of itself the form of the human body, we reprove, with the approval of the aforesaid sacred Council, as erroneous and hostile to the catholic truth of the faith; defining, so that the truth of sincere faith may be known to all and the way to all errors closed lest they creep in, that whoever shall henceforth presume to assert, defend or obstinately hold that the rational or intellective soul is not of itself and essentially the form of the human body, is to be reckoned a heretic.”

“Whereas in certain parts of the world some rashly presume to assert that the christian people ought to receive the holy sacrament of the Eucharist under both species of bread and wine, and give communion to the lay people everywhere not only under the species of bread but also under the species of wine, and even after supper or otherwise not fasting, and obstinately assert that communion must be given so, against the praiseworthy custom of the Church, reasonably approved, which they try to condemn as sacrilegious: hence it is that this present Council … declares, decrees and defines that, although Christ instituted this venerable sacrament after supper and administered it to his disciples under both species of bread and wine, nevertheless, this notwithstanding, the authority of the sacred canons and the praiseworthy and approved custom of the Church has kept and keeps that this sacrament ought not to be confected after supper, nor received by the faithful when not fasting, except in a case of illness or of other necessity granted or admitted by law or by the Church. And just as this custom was reasonably introduced in order to avoid certain dangers and scandals, so, although in the primitive Church this sacrament was received by the faithful under both species, afterwards it came to be received by those confecting it under both, and by the laity only under the species of bread; since it is to be most firmly believed and in no way doubted that the whole body of Christ and his blood are truly contained under the species of bread as well as under the species of wine. Wherefore to say that to observe this custom or law is sacrilegious or unlawful must be judged erroneous, and those obstinately asserting the opposite of the foregoing are to be restrained as heretics and severely punished by the local diocesan bishops or their officials or by the inquisitors of heretical depravity. …”

“In the name of the Holy Trinity, of the Father and of the Son and of the Holy Spirit, with the approval of this sacred universal Council of Florence we define that this truth of faith be believed and accepted by all Christians, and that all so profess it: that the Holy Spirit is eternally from the Father and the Son, and has his essence and his subsistent being from the Father together with the Son, and proceeds from both eternally as from one principle and by a single spiration; declaring that what the holy Doctors and Fathers say — that the Holy Spirit proceeds from the Father through the Son — tends to this understanding, that by it is signified that the Son too is, according to the Greeks the cause, and according to the Latins the principle, of the subsistence of the Holy Spirit, as is the Father. And since all that is the Father's, the Father himself in begetting gave to his only-begotten Son, save being Father, this very thing — that the Holy Spirit proceeds from the Son — the Son himself has eternally from the Father, by whom he was likewise eternally begotten. We define besides that the explanation of those words "Filioque" was lawfully and reasonably added to the Symbol for the sake of declaring the truth, and under the necessity then pressing. Likewise, that the body of Christ is truly confected in unleavened or in leavened wheaten bread, and that priests ought to confect the body of the Lord in either one of these, each according to the custom of his own Church, whether western or eastern.”

“Since therefore in our days — which we report with sorrow — the sower of tares, the ancient enemy of the human race, has dared to sow over and to increase in the field of the Lord certain most pernicious errors, always rejected by the faithful, concerning especially the nature of the rational soul, namely that it is mortal, or one in all men; and since some, rashly philosophising, affirm that this is true at least according to philosophy: desiring to apply fitting remedies against a plague of this kind, with the approval of this sacred Council we condemn and reprove all who assert that the intellective soul is mortal, or one in all men, and those who call these things into doubt — since it not only truly exists of itself and essentially as the form of the human body, as is contained in the canon of Pope Clement V of happy memory, our predecessor, issued in the general Council of Vienne, but is also immortal, and, according to the multitude of the bodies into which it is infused, individually multiplicable, multiplied and to be multiplied. And since truth in no way contradicts truth, we define that every assertion contrary to the truth of the illumined faith is altogether false; and we most strictly forbid that it be lawful to teach otherwise; and we decree that all who adhere to assertions of such error are to be shunned and punished in every way as detestable and abominable heretics and unbelievers, sowing most damnable heresies and undermining the catholic faith.”
