"He is always born at the winter solstice, after the shortest day in the year, at the midnight of the 24th December when the sign Virgo is rising above the horizon; born as this Sign is rising, he is born always of a virgin, and she remains a virgin after she has given birth to her Sun-child as the celestial Virgo remains unchanged and unsullied when the Sun comes forth from her in the Heavens. Weak, feeble as an infant is he, born when the days are shortest and the nights are longest."
~ Annie Besant

The connection to the sun as a solar deity, the light and soul of the world, when it is reborn at the winter solstice, became the birthday of Y'shua, and he is but one manifestation of many ancient savior deities.
