The belief that Mary was a sinner, by means of original sin and/or sinful behavior, was widespread in early Christianity. It predates the view that Mary was sinless. The following are some examples of early denials, either directly or indirectly, that Mary was sinless.
Justin Martyr refers to Jesus as the only sinless person, and he denies that a Jewish opponent he was debating, Trypho, could cite a single other person who obeyed all of God's commandments (Dialogue With Trypho, 17, 88, 95). Irenaeus asks "who else is perfectly righteous, but the Son of God" (Demonstration Of The Apostolic Preaching, 72). Clement of Alexandria writes of Jesus, "He alone is sinless...For this Word of whom we speak alone is sinless. For to sin is natural and common to all." (The Instructor, 1:2, 3:12) Tertullian refers to Mary's "unbelief" and other sins in the process of discussing Matthew 12:46-50 (On The Flesh Of Christ, 7). J.N.D. Kelly wrote, "Origen insisted that, like all human beings, she [Mary] needed redemption from her sins; in particular, he interpreted Simeon's prophecy (Luke 2, 35) that a sword would pierce her soul as confirming that she had been invaded with doubts when she saw her Son crucified." (Early Christian Doctrines [San Francisco, California: HarperCollins Publishers, 1978], p. 493) Origen suggested that he was speaking for all Christians when he wrote:
"While if by those 'who were without sin' he means such as have never at any time sinned,-for he made no distinction in his statement,-we reply that it is impossible for a man thus to be without sin. And this we say, excepting, of course, the man understood to be in Christ Jesus, who 'did no sin.'...God has not been able to prevent even in the case of a single individual, so that one man might be found from the very beginning of things who was born into the world untainted by sin...For in the connected series of statements which appears to apply as to one particular individual, the curse pronounced upon Adam is regarded as common to all (the members of the race), and what was spoken with reference to the woman is spoken of every woman without exception." (Against Celsus, 3:62, 4:40)
Similarly, an anonymous writer of the third century repeats what seems to have been the popular view of the ante-Nicene era: "He [Jesus] alone did no sin at all" (A Treatise On Re-Baptism By An Anonymous Writer, 17). Basil of Caesarea thought that Luke 2:34-35 refers to sinful doubt on Mary's part at the time of Jesus' crucifixion, and that she would need to be restored after Jesus' resurrection, just as Peter was restored (Letter 260:6-9). He considers his interpretation of the passage so popular that he claims there's "no obscurity or variety of interpretation" (Letter 260:6). Michael O'Carroll writes the following about Hilary of Poitiers:
"On the incident of Mary and the brothers waiting outside for Jesus [Matthew 12:46-50], H. [Hilary of Poitiers] proposes a novel exegesis: 'But since he came unto his own and his own did not receive him, in his mother and brothers the Synagogue and the Israelites are foreshadowed, refraining from entry and approach to him.'" (Theotokos [Wilmington, Delaware: Michael Glazier, Inc., 1988], p. 171)
And Cyril of Alexandria:
"In this commentary, C. [Cyril of Alexandria] uses phrases about Mary which seem to continue the opinions of Origen (qv) and St. Basil (qv) on imperfection in her faith: 'In all likelihood, even the Lord's Mother was scandalised by the unexpected passion, and the intensely bitter death on the Cross...all but deprived her of right reason.' He tries to imagine the thoughts that passed through Mary's mind. Had Jesus been mistaken when he said he was the Son of Almighty God? Why was he crucified who said he was the life? Why did he who had brought Lazarus back to life not come down from the Cross? Then he recalls what had been written of the Lord's Mother: Simeon's sword, 'the sharp force of the Passion which could turn a woman's mind to strange thoughts.' The word woman is significant, for C. thought that the frailty of the female sex was a factor in what he then thought was collapse." (p. 113)
Cyril of Jerusalem taught that only Jesus has been sinless, and he believed that Mary needed sanctified:
"For we tell some part of what is written concerning His loving-kindness to men, but how much He forgave the Angels we know not: for them also He forgives, since One alone is without sin, even Jesus who purgeth our sins....Immaculate and undefiled was His generation: for where the Holy Spirit breathes, there all pollution is taken away: undefiled from the Virgin was the incarnate generation of the Only-begotten....This is the Holy Ghost, who came upon the Holy Virgin Mary; for since He who was conceived was Christ the Only-begotten, the power of the Highest overshadowed her, and the Holy Ghost came upon her, and sanctified her, that she might be able to receive Him, by whom all things were made. But I have no need of many words to teach thee that generation was without defilement or taint, for thou hast learned it." (Catechetical Lectures, 2:10, 12:32, 17:6)
John Chrysostom accuses Mary of "self-confidence" and other sins (Homilies On Matthew, 44; Homilies On John, 21). Regarding Augustine, J.N.D. Kelly notes:
"he [Augustine] did not hold (as has sometimes been alleged) that she [Mary] was born exempt from all taint of original sin (the later doctrine of the immaculate conception). Julian of Eclanum maintained this as a clinching argument in his onslaught on the whole idea of original sin, but Augustine's rejoinder was that Mary had indeed been born subject to original sin like all other human beings, but had been delivered from its effects 'by the grace of rebirth'." (Early Christian Doctrines [San Francisco, California: HarperCollins Publishers, 1978], p. 497)
After quoting Ambrose, who said that only Jesus has been conceived without original sin, Augustine comments that Ambrose's view is consistent with "the catholic faith" (On The Grace Of Christ, And On Original Sin, 2:47-48).
Philip Schaff counted seven Roman bishops who denied the sinlessness of Mary (The Creeds Of Christendom [Grand Rapids: Baker Books, 1998], Vol. I, p. 123). Michael O'Carroll comments that the Roman bishop Leo I viewed sin as being communicated by means of sexual intercourse, which is how Mary was conceived (Theotokos [Wilmington, Delaware: Michael Glazier, Inc., 1988], p. 217). O'Carroll writes of another Roman bishop, "On Mt 12:48-50, [Gregory the Great] thinks that Mary momentarily represented the Synagogue, which Christ no longer recognized." (p. 159) Even as late as the second millennium we see the sinlessness of Mary rejected by the Roman bishop Innocent III and other Western sources. O'Carroll cites the Pope saying that Mary was "begotten in guilt", that she needed "cleansing of the flesh from the root of sin" (p. 185).
Justin Martyr refers to Jesus as the only sinless person, and he denies that a Jewish opponent he was debating, Trypho, could cite a single other person who obeyed all of God's commandments (Dialogue With Trypho, 17, 88, 95).
