Are you the kind of person that is swayed more easily by tradition, or are you one of those who is a stickler for truth;
this blog article puts three choices before you regarding the day we should celebrate the birth of the Messiah. This first choice is the most
popular, but least likely--the Winter holiday of Christmas, December 25; it is most popular because it''s root goes back to a universal celebration of the Sun-god Tammuz (AKA Mythra, Ahura Mazda, Rah, Saturn, Zeus, etc.) This second choice is less popular, but more likely--the Fall Feast of Tabernacles; it is less popular because it is more specific to the Jewish Scriptures and more likely for the same reason plus it seems to have the gospel
according to Luke and Josephus to back it up. This second choice is the least popular, yet most likely--Nisan 10, the Spring event of choosing the passover lamb one year old without defect; it is least popular because it is most Jewish and most likely because it not only fits the Messianic pattern of Festival fulfillment, it also can take into account the birth of the Savior as recounted in the gospels according to Matthew and Luke, but also Josephus'' recounting of the Temple Priestly Service Schedule, which appears to be a compromise of David''s assignment which began in Nisan and the post-Babylonian adaptation which may well have begun at Rosh HaShannah in the book of Ezra. Please read the article and choose for yourself as a traditionalist or a seeker of truth.
