Christmas Girls

• Christian feast
The New Testament does not give a date for the birth of Jesus. Around AD 200, Clement of Alexandria wrote that a group in Egypt celebrated the nativity on 25 Pashons. This corresponds to May 20. Tertullian (d. 220) does not mention Christmas as a major feast day in the Church of Roman Africa. However, in Chronographai, a reference work published in 221, Sextus Julius Africanus suggested that Jesus was conceived on the spring equinox, popularizing the idea that Christ was born on December 25. The equinox was March 25 on the Roman calendar, so this implied a birth in December.
De Pascha Computus, a calendar of feasts produced in 243, gives March 28 as the date of the nativity. In 245, the theologian Origen of Alexandria stated that, "only sinners (like Pharaoh and Herod)" celebrated their birthdays. In 303, Christian writer Arnobius ridiculed the idea of celebrating the birthdays of gods. However, since Christmas does not celebrate Christ's birth "as God" but "as man", this is not evidence against Christmas being a feast at this time. Moreover, the fact that the innovation rejecting Donatist Church of North Africa celebrated Christmas suggests that the feast had been established before the living memory of those who began that Church in 311.
