“I would to God that every holy day (including Christmas – ed.) whatsoever besides the Lord’s day were abolished. That zeal which brought them first in, was without all warrant of the Word, and merely followed corrupt reason, forsooth to drive out the holy days of the pagans, as one nail drives out another. Those holy days have been so tainted with superstitions that I wonder we tremble not at their very names.” – Martin Bucer, cited in William Ames, A Fresh Suit Against Human Ceremonies in God’s Worship (1633), pp. 359-60.
“And next in particular, concerning festival days findeth that in the explication of the first head of the first book of discipline it was thought good that the feasts of Christmas, Circumcision, Epiphany, with the feasts of the Apostles, Martyrs, and Virgin Mary be utterly abolished because they are neither commanded nor warranted by Scripture and that such as observe them be punished by Civil Magistrates. Here utter abolition is craved and not reformation of abuses only and that because the observation of such feasts have no warrant from the word of God.” – The Acts of the General Assemblies of the Church of Scotland, December 10, Session 17, 1638, pp. 37-38
