+++ From C.H. Spurgeon’s Treasury of David, on Psalm 81:4.
Ver. 4. For this was a statute for Israel, and a law of the God of Jacob.
When it can be proved that the observance of Christmas, Whitsuntide, and other Popish festivals was ever instituted by a divine statute, we also will attend to them, but not till then. It is as much our duty to reject the traditions of men, as to observe the ordinances of the Lord. We ask concerning every rite and rubric, “Is this a law of the God of Jacob?” and if it be not clearly so, it is of no authority with us, who walk in Christian liberty.
+++ C.H. Spurgeon (December 24, 1871, http://www.swrb.com/catalog/s.htm)
We have no superstitious regard for times and seasons. Certainly we do not believe in the present ecclesiastical arrangement called Christmas. First, because we do not believe in the mass at all, but abhor it, whether it be sung in Latin or in English. Secondly, because we find no Scriptural warrant whatever for observing any day as the birthday of the Savior; and consequently, its observance is a superstition, because not of divine authority. Superstition has fixed most positively the day of our Savior’s birth, although there is no possibility of discovering when it occurred. … It was not till the middle of the third century that any part of the Church celebrated the nativity of our Lord; and it was not till very long after the Western Church had set the example, that the Eastern adopted it. … Probably the fact is that the “holy” days were arranged to fit in with the heathen festivals. We venture to assert, that if there be any day in the year, of which we may be pretty sure that it was not the day on which the Savior was born, it is the 25th of December. … Regarding not the day, let us, nevertheless, give God thanks for the gift of His dear Son. … The Catholics and high Church Episcopalians may have their Christmas one day in 365 but we have a Christ gift the entire year.
