While the name Christmas comes from the fact that the Church celebrates the day with a special Christ Mass, the event itself is recounted in the Infancy Narratives of the Gospel of Matthew, esp. 1:18-25, and the Gospel of Luke, esp. 2:1-20. Each account is unique in its details. Matthew, whom scholars believe was a Jew writing for Jews, provides his readers with the prophetic preparation for Christ. Whereas, Luke, a Greek physician, writes to give an accurate account (Lk. 1:1). The many details of the angelic announcement, visitation to Elizabeth, birth and early years are believed to have been obtained by interviewing the Blessed Virgin. ONLINE BIBLE
