If the Law was annulled why are the all of the Commandments Great and Lessor repeated in the New Testament? And this pagan idea of comparing the birth of Jesus and the Winter Solstice is false, anti-christ will try anything and everything to dilute the Word because of the vendetta they have with God's Children.
The King James Bible
Matthew, chapter 5
"18": For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
