Contrary to what many people think Christmas is a pagan festival. The practice of celebrating Christmas was introduced in the church at the end of the fourth century. The word Christmas in English is Christmas, the union of two words, christ and mass which means Christ’s Mass or Christmas Mass.
December 25th was chosen because it coincided with the pagan festivals that celebrated the Sa and the winter solstice, in adoration to the sun-god, the invictus sun. The sun-god is most likely an indication of Nimrod mentioned in Genesis 10: 8-10. This winter festival was called the Nativity of the Sun. The natalis invicti solar party (Nativity of the unconquered sun) was celebrated on December 25.
Saturnalia is referring to saturnal, from the Latin saturnale, indicates the saturnian god or the feasts in his honor.
Solstice comes from the Latin solstitiu. Time when the sun passes through its greater boreal or austral declination, and during which it ceases to move away from the equator. The solstices are respectively on June 22 or 23 for the largest boreal declination, and on December 22 or 23 for the largest southern declination of the sun. In the southern hemisphere, the first date is called the winter solstice and the second summer solstice; and, as the seasons are opposite in the two hemispheres, these denominations invert in the northern hemisphere. So … Merry Christmas …
