- Jesus was most likely not born on any date corresponding to December 25, the date on which his birth is traditionally celebrated as Christmas. It is more likely that his birth was in either the season of spring or perhaps summer, while December 25 in the Northern Hemisphere is at the beginning of winter. Also, although the Common Era ostensibly counts the years since his birth, it is unlikely that he was born in either AD 1 or 1 BC, as such a numbering system would imply. Modern historians estimate a date closer to between 6 BC and 4 BC.
- The Bible does not say that exactly three magi came to visit the baby Jesus, nor that they were kings, or rode on camels, or that their names were Casper, Melchior, and Balthazar, nor what color their skin was. Three magi are inferred because three gifts are described, but the Bible says only that there was more than one; still, artistic depictions of the nativity have almost always depicted three magi since the 3rd century. The Bible only specifies an upper limit of 2 years for the interval between the birth and the visit (Matthew 2:16[non-primary source needed]), and artistic depictions and the closeness of the traditional dates of December 25 and January 6 encourage the popular assumption that the visit took place in the same season as the birth, but later traditions varied, with the visit taken as occurring up to two years later. The association of magi with kings comes from efforts to tie the visit to prophecies in the Book of Isaiah.
- The idea that Mary Magdalene
was a prostitute before she met Jesus is not found in the Bible or in
any of the other earliest Christian writings. The misconception likely
arose due to a conflation between Mary Magdalene, Mary of Bethany (who anoints Jesus's feet in John 11:1–12), and the unnamed "sinful woman" who anoints Jesus's feet in Luke 7:36–50.
