Was Mary free from sin, and from when?

What the early Church said, in their own words →

Immaculate Conception Catholic

Every deciding passage, earliest first
Hesychius of Jerusalem, c. 450
The Virgin Mary kept her breasts untouched and nursed a child without knowing the child's father. She became a mother without becoming a bride, a remarkable and unprecedented event. A son was being raised, and yet, a father was not found. The field was bearing fruit, but the fruit had no farmer to tend to it. It yielded a harvest, but it did not receive seed. A river was flowing, and its source was closed from everywhere, signifying that Mary had become a mother without suffering the things that mothers normally experience. She gave birth like a woman, but she was not corrupted like a woman. H…
- Rejects: Mary had personal faults
Hesychius of Jerusalem, c. 450
The sign of contradiction is the cross. For when the Jews crucified him, the sun withdrew; the synagogue slandered him, and the earth shook. The crowd cried out, “Crucify him” (Luke 23:21), but the rocks, unable to bear the weight of the blasphemy, split apart. The elders and the scribes said, “We remember that this deceiver said while he was still alive, ‘After three days I will rise’” (Matthew 27:63). But the centurion cried out, “Truly this was the Son of God” (Matthew 27:54). And even to this day the word of the cross is “a stumbling block to Jews and foolishness to Gentiles, but to us who…

How this was made
Every whole work in the library on 21 October 2026 was searched for this question. Works added since then are not searched yet. The short excerpts on the topic pages (many from Tertullian, Justin, Irenaeus and Ignatius) join the search once their English has been checked against the Greek or Latin original: 94% of them (1,814 of 1,925) have passed that check, and the rest are still held out, so an early witness may occasionally be missing from these lanes. Two AI models from different labs judged each passage against all the positions at once, seeing them only as letters, without names or churches. A third model settled disagreements, and Claude reviewers then checked every deciding verdict against the passage and, for the earliest dates, against the Greek or Latin. A writer's silence is never counted.
The evidence is only as deep as the works searched: 1st century: 5 writers, 2nd century: 23 writers, 3rd century: 22 writers, 4th century: 18 writers, 5th century: 11 writers, 6th century: 5 writers, 8th century: 1 writer. The lanes are redrawn when the search is run again.
