Lateran Council IV, 1215 — Ecumenical XII (against the Albigensians, Joachim, Waldensians etc

Chap. 1. The Catholic Faith

(Definition directed against the Albigensians and other heretics]

Firmly we believe and we confess simply that the true God is one alone, eternal, immense, and unchangeable, incomprehensible, omnipotent and ineffable, Father and Son and Holy Spirit: indeed three Persons but one essence, substance, or nature entirely simple. The Father from no one, the Son from the Father only, and the Holy Spirit equally from both; without beginning, always, and without end; the Father generating, the Son being born, and the Holy Spirit proceeding; consubstantial and coequal and omnipotent and coeternal; one beginning of all, creator of all visible and invisible things, of the spiritual and of the corporal; who by His own omnipotent power at once from the beginning of time created each creature from nothing, spiritual, and corporal, namely, angelic and mundane, and finally the human, constituted as it were, alike of the spirit and the body. For the devil and other demons were created by God good in nature, but they themselves through themselves have become wicked. But man sinned at the suggestion of the devil. This Holy Trinity according to common essence undivided, and according to personal properties distinct, granted the doctrine of salvation to the human race, first through Moses and the holy prophets and his other servants according to the most methodical disposition of the time.

And finally the only begotten Son of God, Jesus Christ, incarnate by the whole Trinity in common, conceived of Mary ever Virgin with the Holy Spirit cooperating, made true man, formed of a rational soul and human flesh, one Person in two natures, clearly pointed out the way of life. And although He according to divinity is immortal and impassible, the very same according to humanity was made passible and mortal, who, for the salvation of the human race, having suffered on the wood of the Cross and died, descended into hell, arose from the dead and ascended into heaven. But He descended in soul, and He arose in the flesh, and He ascended equally in both, to come at the end of time, to judge the living and the dead, and to render to each according to his works, to the wicked as well as to the elect, all of whom will rise with their bodies which they now bear, that they may receive according to their works, whether these works have been good or evil, the latter everlasting punishment with the devil, and the former everlasting glory with Christ.

One indeed is the universal Church of the faithful, outside which no one at all is saved, * in which the priest himself is the sacrifice, Jesus Christ, whose body and blood are truly contained in the sacrament of the altar under the species of bread and wine; the bread (changed) into His body by the divine power of transubstantiation, and the wine into the blood, so that to accomplish the mystery of unity we ourselves receive from His (nature) what He Himself received from ours. And surely no one can accomplish this sacrament except a priest who has been rightly ordained according to the keys of the Church which Jesus Christ Himself conceded to the Apostles and to their successors. But the sacrament of baptism (which at the invocation of God and the indivisible Trinity, namely, of the Father and of the Son and of the Holy Spirit, is solemnized in water) rightly conferred by anyone in the form of the Church is useful unto salvation for little ones and for adults. And if, after the reception of baptism, anyone shall have lapsed into sin, through true penance he can always be restored. Moreover, not only virgins and the continent but also married persons pleasing to God through right faith and good work merit to arrive at a blessed eternity.

We condemn, therefore, and we disapprove of the treatise or tract which Abbot Joachim published against Master Peter Lombard on the unity or essence of the Trinity, calling him heretical and senseless because in hisSentenceshe said: "Since it is a most excellent reality-the Father, and the Son, and the Holy Spirit, and it is not generating, nor generated, nor proceeding." * Thus he (Joachim) declares that Peter Lombard implies not so much a Trinity as a quaternity in God, namely the three Persons and that common essence as a fourth, openly protesting that there is no matter which is the Father and the Son and the Holy Spirit; neither is there essence, nor substance, nor nature, although he concedes that the Father, and the Son. and the Holy Spirit are one essence, one substance, and one nature. But he says that unity of this kind is not true and proper, but is something collective and similar, as many men are called one people, and many faithful, one Church, according to the following: "Of the multitude believing there was one heart and one mind" [ Acts 4:32]; and, "He who clings to God is one spirit with him" [ 1 Cor. 6:17]; likewise, "He who . . . plants and he who waters are one" [ 1 Cor. 3:8]; and, "we are all one body in Christ" [ Rom. 12:5]; again in the Book of Kings [Ruth]: "My people and your people are one" [Ruth 1:16]. Moreover, to add to this opinion of his he brings the following most powerful expression, that Christ spoke in the Gospel about the faithful: "I will, Father, that they are one in us as we are one, so that they may be perfected in unity" [John 17:22 f.]. For not, (as he says), are the faithful of Christ one, that is, a certain one matter which is common to all, but in this way are they one, that is, one Church because of the unity of the Catholic faith; and finally one kingdom, because of the union of indissoluble love, as in the canonical letter of John the Apostle we read: "For there are three that give testimony in heaven, the Father, and the Son, and the Holy Spirit, and these three are one" [ 1 John 5:7], and immediately is added: "And there are three who give testimony on earth, the Spirit, the water, and the blood, and these three are one" [ 1 John 5:8 ], as is found in certain texts.

We, however, with the approval of the sacred Council, believe and confess with Peter Lombard that there exists a most excellent reality, incomprehensible indeed and ineffable, which truly is the Father, and the Son, and the Holy Spirit, at the same time three Persons, and anyone of the same individually; and so in God there is Trinity only, not a quaternity; because any one of the three Persons is that reality, namely, substance, essence or divine nature, which alone is the beginning of all things, beyond which nothing else can be found, and that reality is not generating, nor generated, nor proceeding, but it is the Father who generates, the Son who is generated, and the Holy Spirit who proceeds, so that distinctions are in Persons and unity in nature. Therefore, although "one is the Father, another the Son, and another the Holy Spirit, yet they are not different" * but what is the Father is the Son and the Holy Spirit entirely the same, so that according to the true and Catholic Faith they are believed to be consubstantial. For the Father from eternity by generating the Son gave His substance to Him according to which He Himself testifies: "That which the Father has given to me is greater than all things" [John 10:29]. But it cannot be said that He (the Father) has given a part of His substance to Him (the Son), and retained a part for Himself, since the substance of the Father is indivisible, namely, simple. But neither can it be said that the Father has transferred His substance to the Son in generating, as if He had given that to the Son which he did not retain for Himself; otherwise the substance would have ceased to exist. It is clear, therefore, that the Son in being born without any diminution received the substance of the Father, and thus the Father and the Son have the same substance, and so this same reality is the Father and the Son and also the Holy Spirit proceeding from both. But when Truth prays to the Father for His faithful saying: "I will that they may be one in us, as we also are one" [ John 17:22]: this word "one" indeed is accepted for the faithful in such a way that a union of charity in grace is understood, for the divine Persons in such a way that a unity of identity in nature is considered, as elsewhere Truth says: "Be . . . perfect, as also your heavenly Father is perfect" [Matt. 5:48 ], as if He said more clearly, "Be perfect" in the perfection of grace "as your heavenly Father is perfect" in the perfection of grace, that is, each in his own manner, because between the Creator and the creature so great a likeness cannot be noted without the necessity of noting a greater dissimilarity between them. If anyone, therefore, shall presume to defend or approve the opinion or doctrine of the above mentioned Joachim, let him be refuted as a heretic by all.

Yet on this account we do not wish to detract from the monastery in Florence (whose founder is Joachim himself), since both the institution there is regular and the observance salutary, especially since Joachim himself has ordered all his writings to be assigned to us, to be approved or even corrected by the judgment of the Apostolic See, dictating a letter which he signed with his own hand in which he firmly confesses that he holds that Faith which the Roman Church, which (the Lord disposing) is the mother and master of all the faithful, holds. We reprove also and we condemn that very perverse dogma of the impious Almaricus, whose mind the father of lies has so blinded that his doctrine must be considered not so heretical as insane.

[The necessity of a canonical mission]

Because some indeed "under the pretext of piety, denying his power" (according to what the Apostle says) [2 Tim. 3:5], assume to themselves the authority of preaching, when the same Apostle says: "How . . . shall they preach, unless they are sent?" [Rom. 10:15 ], let all who, being prohibited or not sent, without having received authority from the Apostolic See, or from the Catholic bishop of the place, shall presume publicly or privately to usurp the duty of preaching * be marked by the bond of excommunication; and unless they recover their senses, the sooner the better, let them be punished with another fitting penalty.

Although we wish to cherish and honor the Greeks who in our days are returning to the obedience of the Apostolic See, by sustaining their customs and rites in as far as we are able with the Lord, yet we do not wish nor are we able to defer to them in these things which engender danger to souls and which detract from ecclesiastical honor. For when the church of the Greeks with certain accomplices and their protectors withdrew itself from the obedience of the Apostolic See, the Greeks began to detest the Latins so much that among other things which they impiously committed to their dishonor, if at any time Latin priests celebrated Mass on their altars, they themselves were unwilling to sacrifice on these (altars), before they washed them, as if defiled on account of this (sacrifice by the Latin priests); these same Greeks presumed with indiscreet boldness to rebaptize those baptized by the Latins, and up to this time, as we have learned, certain ones do not fear to do this. Therefore, wishing to remove such scandal from the Church, on the recommendation of the Sacred Council, we strictly command that they do not presume such things in the future, conforming themselves as obedient sons to the holy Roman Church, their mother, so that there may be "one flock and one shepherd" [John 10:16]. If anyone, however, shall presume any such thing, struck by the sword of excommunication, let him be deposed from every office and ecclesiastical favor.

Renewing the ancient privilege of the patriarchal sees, with the approval of the sacred universal synod, we sanction that after the Roman Church, which by the ordering of the Lord before all others holds the first place of ordinary power as the mother and teacher of all the faithful of Christ, the (Church of) Constantinople holds the first, Alexandria the second, Antioch the third, and Jerusalem the fourth place.

Chap. 21.The Obligation of Making Confession and of its not being Revealed by the Priest, and the Obligation of Receiving

Let everyone of the faithful of both sexes, after he has arrived at the years of discretion, alone faithfully confess all his sins at least once a year to his own priest, and let him strive to fulfill with all his power the penance enjoined upon him, receiving reverently the sacrament of the Eucharist at least in Paschal time, unless by chance on the advice of his own priest for some reasonable cause it shall be decided that he must abstain from the precept temporarily; otherwise both while living let him be barred from entrance to the church, and when dying let him be deprived of Christian burial. Therefore, let this salutary law be published frequently in the churches, lest anyone assume a pretext of excuse in the blindness of ignorance. Moreover if anyone from a just cause shall wish to confess his sins to another priest, let him first ask and obtain permission from his own priest, since otherwise that one (the other priest) cannot absolve or bind him. Let the priest, however, be discreet and cautious, so that skilled by practice "he may pour wine and oil" [ Luke 10:34] on the wounds of the wounded, diligently inquiring into both the circumstances of the sinner and the sin, by which prudently he may understand what kind of advice he ought to give to him, and, using various experiments to save the sick, what kind of a remedy he ought to apply.

Moreover, let him constantly take care, lest by word or sign or any other way whatsoever he may at any time betray the sinner; but if he should need more prudent counsel, he should seek it cautiously without any mention of the person, since he who shall presume to reveal a sin entrusted to him in confession, we decree not only must be deposed from priestly office but must also be thrust into a strict monastery to do perpetual penance.

Since "everything . . . which is not from faith is a sin" [ Rom. 14:23 ], by synodal judgment we define that no precept either canonical or civil without good faith has any value, since that which cannot be observed without mortal sin must in general be rejected by every constitution and custom. Therefore, it is necessary that he who lay down a rule at no time be conscious of anything wrong.

Since, because certain ones expose the relics of saints for sale and exhibit them at random, the Christian religion has often suffered detraction; so that it may not suffer detraction in the future, we have ordered by the present decree that from now on ancient relics may by no means be exhibited or exposed for sale outside a case. Moreover let no one presume that newly found relics be venerated publicly, unless first they have been approved by the authority of the Roman Pontiff
