Much of what makes up the Merry Christmas of society has no place in the teaching and example of Jesus Christ. Every serious student of the Bible knows that the discipleship to which Christ calls his followers cannot accommodate the lifestyle of the unbelieving world. It is obvious that for the unbelieving world Christmas is a social celebration to which has been attached the name of Christ. Jesus Christ is not in it. It is this, that Christian beliefs and practices are based on the Bible.
Christians find in the Scriptures the convictions to which they hold.
From it they believe in the divine Person of Jesus Christ, the Person of the Holy Spirit, man's need of regeneration, justification by faith alone, and the certainty of the great Judgement Day. From the Bible, according to Christ's appointment, Christians remember His death in the Sacrament of the Lord's Supper. The Bible clearly gives an account of Christ's birth in the Gospels. You cannot be a Christian unless you believe in the supernatural conception and virgin birth of the Saviour. The Incarnation is a great mystery, but a matter of divine revelation and consequently of faith.
