My first thought and answer is no. I do not "BELIEVE" in Santa Clause, but I do BELIEVE in the birth of Jesus, who walked this earth in order to fulfill the law, becoming the perfect Lamb of God, living life to die upon the cross in order to redeem us from Sin. If we will "esteem" the chosen day to celebrate His birth, and give gifts to one another with love, then we celebrate the day "unto the Lord".
The world has come to celebrate "Christmas" given into believing that it is all about Santa Clause, making him their idol. God said "Exo 20:3 Thou shalt have no other gods before me.
Exo 20:4 Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth:
Exo 20:5 Thou shalt not bow down thyself to them, nor serve them: for I the LORD thy God am a jealous God..... "
