The Council of Carthage (417-418) Condemns Pelagianism.

 

                        Pelagius the Ascetic and Heretic Monk

Background

Pelagianism is a Heresy theological position that holds that the fall did not taint human nature and that humans by divine grace have free will to achieve human perfection. Pelagius (c. 355 – c. 420 AD), an ascetic and philosopher from the British Isles, taught that God could not command believers to do the impossible, and therefore it must be possible to satisfy all divine commandments. He also taught that it was unjust to punish one person for the sins of another; therefore, infants are born blameless. Pelagius accepted no excuse for sinful behaviour and taught that all Christians, regardless of their station in life, should live unimpeachable, sinless lives. With other words, Pelagius taught that there is no Original Sin. 

As St. Augustine (De peccat. orig., xxiv) testifies that he lived in Rome "for a very long time", we may presume that he resided there at least since the reign of Pope Anastasius (398-401). But about his long life prior to the year 400 and above all about his youth, we are left wholly in the dark. 

Pelagius was highly educated, spoke and wrote Latin as well as Greek with great fluency and was well versed in theology. Though a monk and consequently devoted to practical asceticism, he never was a cleric; for both Orosius and Pope Zosimus simply call him a "layman".

Pelagius denied the primitive state in paradise and original sin (cf. P.L., XXX, 678, "Insaniunt, qui de Adam per traducem asserunt ad nos venire peccatum"), insisted on the naturalness of concupiscence and the death of the body, and ascribed the actual existence and universality of sin to the bad example which Adam set by his first sin. As all his ideas were chiefly rooted in the old, pagan philosophy, especially in the popular system of the Stoics, rather than in Christianity, he regarded the moral strength of man's will (liberum arbitrium), when steeled by asceticism, as sufficient in itself to desire and to attain the loftiest ideal of virtue. The value of Christ's redemption was, in his opinion, limited mainly to instruction (doctrina) and example (exemplum), which the Saviour threw into the balance as a counterweight against Adam's wicked example, so that nature retains the ability to conquer sin and to gain eternal life even without the aid of grace. By justification we are indeed cleansed of our personal sins through faith alone (loc. cit., 663, "per solam fidem justificat Deus impium convertendum"), but this pardon (gratia remissionis) implies no interior renovation of sanctification of the soul. How far the sola-fides doctrine "had no stouter champion before Luther than Pelagius" and whether, in particular, the Protestant conception of fiducial faith dawned upon him many centuries before Luther, as Loofs ("Realencyklopädies fur protest. Theologie", XV, 753, Leipzig, 1904) assumes, probably needs more careful investigation. For the rest, Pelagius would have announced nothing new by this doctrine, since the Antinomists of the early Apostolic Church were already familiar with "justification by faith alone". On the other hand, Luther's boast of having been the first to proclaim the doctrine of abiding faith, might well arouse opposition. However, Pelagius insists expressly (loc. cit. 812), "Ceterum sine operibus fidei, non legis, mortua est fides". But the commentary on St. Paul is silent on one chief point of doctrine, i.e. the significance of infant baptism, which supposed that the faithful were even then clearly conscious of the existence of original sin in children. With other words, Pelagius taught that infant baptism is not necessary for babies as soul salvation. 

Pelagius and Caelestius (411-415)

Of far-reaching influence upon the further progress of Pelagianism was the friendship which Pelagius contracted in Rome with Caelestius, a lawyer of noble (probably Italian) descent. A eunuch by birth, but endowed with no mean talents, Caelestius had been won over to asceticism by his enthusiasm for the monastic life, and in the capacity of a lay-monk he endeavoured to convert the practical maxims learnt from Pelagius, into theoretical principles, which successfully propagated in Rome. St. Augustine, while charging Pelagius with mysteriousness, mendacity, and shrewdness, calls Caelestius (De peccat. orig., xv) not only "incredibly loquacious", but also open-hearted, obstinate, and free in social intercourse. Even if their secret or open intrigues did not escape notice, still the two friends were not molested by the official Roman circles. But matters changed when in 411 they left the hospitable soil of the metropolis, which had been sacked by Alaric (410), and set sail for North Africa. When they landed on the coast near Hippo, Augustine, the bishop of that city, was absent, being fully occupied in settling the Donatist disputes in Africa. Later, he met Pelagius in Carthage several times, without, however, coming into closer contact with him. After a brief sojourn in North Africa, Pelagius travelled on to Palestine, while Caelestius tried to have himself made a presbyter in Carthage. But this plan was frustrated by the deacon Paulinus of Milan, who submitted to the bishop, Aurelius, a memorial in which six theses of Caelestius — perhaps literal extracts from his lost work "Contra traducem peccati" — were branded as heretical. These theses ran as follows:

1. Even if Adam had not sinned, he would have died.
2. Adam's sin harmed only himself, not the human race.
3. Children just born are in the same state as Adam before his fall.
4. The whole human race neither dies through Adam's sin or death, nor rises again through the resurrection of Christ.
5. The (Mosaic Law) is as good a guide to heaven as the Gospel.
6. Even before the advent of Christ there were men who were without sin.

On account of these doctrines, which clearly contain the quintessence of Pelagianism, Caelestius was summoned to appear before a synod at Carthage (411); but he refused to retract them, alleging that the inheritance of Adam's sin was an open question and hence its denial was no heresy. Catholic Church condemned Pelagius with his teaching later on Holy Synod of Carthage (417-418), In the consulate of the most glorious Emperors, Honorius for the XIIth time and Theodosius for the VIIIth, Augusti most exalted, on the Calends of May, at Carthage in the secretarium of the Basilica of Faustus. When Aurelius the bishop presided over the whole council, the deacons standing by, it pleased all the bishops, whose names and subscriptions are indicated, met together in the Holy Synod of the Church of Carthage to define :

1) That Adam was not created by God subject to death. (Canon 1 of 418 Synod)
That whosoever says that Adam, the first man, was created mortal, so that whether he had sinned or not, he would have died in body—that is, he would have gone forth of the body, not because his sin merited this, but by natural necessity, let him be anathema.

2) That infants are baptized for the remission of sins. (Canon 2 of 418 Synod)
Likewise it seemed good that whosoever denies that infants newly from their mother’s wombs should be baptized, or says that baptism is for remission of sins, but that they derive from Adam no original sin, which needs to be removed by the laver of regeneration, from whence the conclusion follows, that in them the form of baptism for the remission of sins, is to be understood as false and not true, let him be anathema. For no otherwise can be understood what the Apostle says, “By one man sin is come into the world, and death through sin, and so death passed upon all men in that all have sinned,” than the Catholic Church everywhere diffused has always understood it. For on account of this rule of faith even infants, who could have committed as yet no sin themselves, therefore are truly baptized for the remission of sins, in order that what in them is the result of generation may be cleansed by regeneration.

3) That the grace of God not only gives remission of sins, but also affords aid that we sin no more. (Canon 3 of 418 Synod)
Likewise it seemed good, that whoever should say that the grace of God, by which a man is justified through Jesus Christ our Lord, avails only for the remission of past sins, and not for assistance against committing sins in the future, let him be anathema.

4) That the grace of Christ gives not only the knowledge of our duty, but also inspires us with a desire that we may be able to accomplish what we know. (Canon 4 of 418 Synod)
Also, whoever shall say that the same grace of God through Jesus Christ our Lord helps us only in not sinning by revealing to us and opening to our understanding the commandments, so that we may know what to seek, what we ought to avoid, and also that we should love to do so, but that through it we are not helped so that we are able to do what we know we should do, let him be anathema. For when the Apostle says: “Wisdom puffeth up, but charity edifieth” it were truly infamous were we to believe that we have the grace of Christ for that which puffeth us up, but have it not for that which edifieth, since in each case it is the gift of God, both to know what we ought to do, and to love to do it; so that wisdom cannot puff us up while charity is edifying us. For as of God it is written, “Who teacheth man knowledge,” so also it is written, “Love is of God.”

5) That without the grace of God we can do no good thing. (Canon 5 of 418 Synod)
It seemed good that whosoever should say that the grace of justification was given to us only that we might be able more readily by grace to perform what we were ordered to do through our free will; as if though grace was not given, although not easily, yet nevertheless we could even without grace fulfil the divine commandments, let him be anathema. For the Lord spake concerning the fruits of the commandments, when he said: “Without me ye can do nothing,” and not “Without me ye could do it but with difficulty.”

6) That not only humble but also true is that voice of the Saints: “If we say that we have no sin we deceive ourselves.” (Canon 6 of 418 Synod)
It also seemed good that as St. John the Apostle says, “If we shall say that we have no sin we deceive ourselves and the truth is not in us,” whosoever thinks that this should be so understood as to mean that out of humility, we ought to say that we have sin, and not because it is really so, let him be anathema. For the Apostle goes on to add, “But if we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all iniquity,” where it is sufficiently clear that this is said not only of humility but also truly. For the Apostle might have said, “If we shall say we have no sins we shall extoll ourselves, and humility shall have no place in us;” but when he says, “we deceive ourselves and the truth is not in us” he sufficiently intimates that he who affirmed that he had no sin would speak not that which is true but that which is false.

7) That in the Lord’s Prayer the Saints say for themselves: “Forgive us our trespasses.” (Canon 7 of 418 Synod)
It has seemed good that whoever should say that when in the Lord’s prayer, the saints say, “forgive us our trespasses,” they say this not for themselves, because they have no need of this petition, but for the rest who are sinners of the people; and that therefore no one of the saints can say, “Forgive me my trespasses,” but “Forgive us our trespasses;” so that the just is understood to seek this for others rather than for himself; let him be anathema. For holy and just was the Apostle James, when he said, “For in many things we offend all.” For why was it added “all,” unless that this sentence might agree also with the psalm, where we read, “Enter not into judgment with thy servant, O Lord, for in thy sight shall no man living be justified;” and in the prayer of the most wise Solomon: “There is no man that sinneth not;” and in the book of the holy Job: “He sealeth in the hand of every man, that every man may know his own infirmity;” wherefore even the holy and just Daniel when in prayer said several times: “We have sinned, we have done iniquity,” and other things which there truly and humbly he confessed; nor let it be thought (as some have thought) that this was said not of his own but rather of the people’s sins, for he said further on: “When I shall pray and confess my sins and the sins of my people to the Lord my God;” he did not wish to say our sins, but he said the sins of his people and his own sins, since he as a prophet foresaw that those who were to come would thus misunderstand his words.

8) That the Saints say with accuracy, “Forgive us our trespasses.” (Canon 8 of 418 Synod)
Likewise also it seemed good, that whoever wished that these words of the Lord’s prayer, when we say, “Forgive us our trespasses” are said by the saints out of humility and not in truth let them be anathema. For who would make a lying prayer, not to men but to God? Who would say with his lips that he wished his sins forgiven him, but in his heart that he had no sins to be forgiven.

Pelagianism Heritages on Modern Era :

As we know because Pelagianism rejects Original sin concept and teaches about unnecessary for infant baptism. It influences Some Protestant denominations including Mennonites, Baptists, Anabaptists, Quakers, and Pentacostals or Charismatics who deny infant baptism as valid baptism. 

About rejection of Original sin, it also influences Mahometanism teaching for today which rejects if there is an Original sin. 

Pelagianism teaching is more like Buddhism on its way to teach about moral without faith can saves soul to Heaven.
