This article is part of the 10 Things You Should Know series.
1. We know very little about Pelagius (350-425) prior to his conflict with Augustine.
Evidently he was a British monk who taught for a short time in Rome toward the close of the 4th century. He fled to North Africa in 410 (preceding the invasion of the Goths) and there engaged in his dispute with Augustine, the famous Bishop of Hippo. He later went to Palestine and then disappeared from history.
2. Pelagius was a prolific author who preferred written treatises and rebuttals to open verbal confrontation.
His writings reflect his excellent education and were characterized by clarity of thought and devotional tones throughout. They centered primarily in ethics and religious piety. The hallmark of the Pelagian literature was the insistence that all believers were morally obligated to high ethical ideals, not just the clergy.
3. He wrote several scholarly commentaries on the Pauline epistles as well as a number of letters during the course of the controversy, few of which have survived.
Included among his works are The Hardening of Pharaoh's Heart, Virginity, The Law, and Faith in the Trinity (an anti-Arian treatise). His two most influential works are his De Natura and his treatise on Free Will. This latter work, which survives only in fragments today, contains four points of emphasis:
a. Men are born morally neutral with an equal capacity for either good or evil.
b. Whereas previously he spoke of divine grace as merely providing help, here he seems to assert it is necessary for salvation.
c. He finally admits that Adam's sin did adversely affect his posterity, but only by way of setting a bad example.
d. He discusses certain texts in Paul that appear to say we are driven to sin by the corruption of our flesh, a doctrine he rejects.
4. Pelagius was first and foremost a moralist.
It is important to keep this in mind as a foundational assumption in all of Pelagius' thinking. He was concerned above all else with right conduct. He was especially hostile to what he perceived to be the tendency of grace to grant a license for sin (cf. Rom. 5:21-6:2). Consider the following statement:
Whenever I am called upon to speak upon moral training and the course of holy living, I am accustomed first to display the power and quality of human nature and show what it is able to accomplish, and then from this to incite the mind of the hearer to (some) forms of virtue, lest it profit nothing to summon to those things which it would have thought to be impossible for it.1
5. Pelagius believed that the soul of man by creation is neither holy nor sinful.
According to Pelagius, Adam was not created holy. He was not constitutionally inclined either toward good or evil. He was morally indifferent or neutral. In this state of moral equilibrium, Adam was no more disposed to good than to evil. Pelagius argued that if Adam had possessed any moral character prior to moral action, his moral responsibility would be destroyed.
Because he was a creature, Adam's body was mortal. That is to say, it was Adam's destiny to die physically whether or not he ever sinned. Physical death, therefore, is not a penalty for sin passed on to Adam's posterity, but is rather an inevitable corollary to man's essential character as created.
6. Adam's fall was occasioned by the exercise of free will.
In Pelagius’s thinking, there was nothing in Adam's nature, either for good or ill, that inclined him in the decision he made. Furthermore, Adam's sin in no way affected his posterity except insofar as it set a bad example for them. Referring to Paul's statement in Romans 5:12, Pelagius insisted that "It is said we sinned in Adam, not because sin is innate, but because it comes from imitation [emphasis mine].”2
Consequently, all men come into being in the exact condition as was Adam before the fall. Pelagius believed each soul is created immediately by God and thus cannot come into the world contaminated or corrupted by the sin of Adam. The doctrine of transmitted sin (tradux peccati) or original sin (peccatum originis), says Pelagius, is blasphemous.:
"A sin propagated by generation is totally contrary to the catholic faith. Sin is not born with man, but is committed afterwards by man. It is not the fault of nature, but of free will." [emphasis mine] 3
Thus, according to Pelagius, an infant is not born in sin nor does it possess any innate moral characteristics. Such are obtained only by the exercise of the will and the habits that develop from it. In other words, we are “socialized” to sin or “conditioned” to sin because of continual exposure to a family and society that are themselves sinful for the same reasons.

7. Pelagius denied that the fall of Adam had any adverse influence on the will of man.
According to Pelagius, each act of will is causeless, i.e., it is purely spontaneous and unaffected by any antecedent bias of nature. Pelagius recognized three elements in the human will: 1) the power or capacity to will; 2) the willing; 3) the realization or acting.
The first of these is a gift of God but the other two are wholly of man. Hence the power to will good and the power to will evil are equal. The only difficulty to doing and choosing the good arises from a long continued habit of vice which, according to Pelagius, could be abandoned at any time in favor of virtue. Pelagius defines free will as follows: “But we say that man is always able both to sin and not to sin, so that we confess ourselves to have always a free will.”
Thus, free will consists of: 1) the ability to sin (posse peccare) and 2) the ability not to sin (posse non peccare). These two abilities or powers are always equally at man's disposal. In sum, according to Pelagius, ability limits obligation, or ability is the measure of moral responsibility.
8. Pelagius argued that sin consists solely in separate acts of the will.
Sin is never a matter of nature. That is to say, there is no such thing as a sin nature or constitutional depravity. Sin is only sin when it can be avoided. To speak of inability is to eliminate responsibility, without which there can be no sin. Thus, sin is not a fault of nature but of choice.
Why, then, is sin universally present in the human race? Pelagius' only explanation is: imitation, or the “long practice of sinning and the long habit of vices.” 4
"For no other cause occasions for us the difficulty of doing good than the long custom of vices, which has infected us from childhood, and gradually, through many years, corrupted us, and thus holds us afterward bound and addicted to itself, so that it seems in some way to have the force of nature."5
9. Pelagius was confused about our need for grace.
In one place Pelagius says that grace is absolutely necessary and is needed “not only for every hour or for every moment, but even for every separate act.” 6 Again he says: “Grace is given in order that what is commanded by God may be more easily fulfilled.” 7 And yet other texts point to his belief that grace is entirely superfluous. Adolph Harnack argues that “it was assuredly the chief intention of Pelagius to deprive Christians of their indolent reliance on grace.” 8
There are four elements in Pelagius' doctrine of grace: 1) the grace of creation or life itself; 2) the fact that we have free will is a manifestation of divine grace; i.e., the ability not to sin is grace; 3) grace is also manifest in the revelation of God through the Law; i.e., the provision by God of instruction, doctrine, commands and prohibitions, as well as reward and punishment; 4) the coming of Christ to teach and to set a godly example.
The emphasis is on the latter two elements of grace. Thus grace is primarily external, consisting in the aids or examples or exhortations given by God to encourage us in the pursuit of purity. Grace is not internal. Pelagius rejects any notion of an inward empowerment of the soul or will.
All this implies, of course, that if you are extremely talented and self-disciplined and highly-motivated, you may not need grace at all. In other words, Pelagius’ concept of divine grace, at least potentially, makes the death and resurrection of Christ unnecessary.
10. Pelagius was eventually condemned as a heretic.
Pelagius was acquitted of the charge of heresy by a synod of bishops at Diospolis in Palestine in 415. However, he was later condemned as a heretic by the bishop of Rome in 417 and 418 and by the Council of Ephesus in 431.
