"Increasingly in the late sixteenth and early seventeenth centuries, many people, especially the more Godly, came to frown upon this celebration of Christmas, for two reasons. Firstly, they disliked all the waste, extravagance, disorder, sin and immorality of the Christmas celebrations. Secondly, they saw Christmas (that is, Christ’s mass) as an unwelcome survival of the Roman Catholic faith, as a ceremony particularly encouraged by the Catholic church and by the recusant community in England and Wales, a popish festival with no biblical justification – nowhere had God called upon mankind to celebrate Christ’s nativity in this way, they said. What this group wanted was a much stricter observance of the Lord’s day (Sundays), but the abolition of the popish and often sinful celebration of Christmas, as well as of Easter, Whitsun and assorted other festivals and saints’ days.With all the talk about "war on Christmas" everywhere, I thought it would be appropriate to show that the only ones ever at war with Christmas were Christians themselves.
Specific penalties were to be imposed on anyone found holding or attending a special Christmas church service, it was ordered that shops and markets were to stay open on 25 December, the Lord Mayor was repeatedly ordered to ensure that London stayed open for business on 25 December, and when it met on 25 December 1656 the second Protectorate Parliament discussed the virtues of passing further legislation clamping down on the celebration of Christmas (though no Bill was, in fact, produced)."
