A couple notable men who are recorded to have been critical of Christmas for its papal origins would include Charles Spurgeon and Calvin.
Spurgeon seemed to have personally rejected Christmas, yet he didn’t see fit to go out of his way to fight against it. Here are a couple really good quotes from him on the topic. One of them:
“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; and 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 twenty-fifth of December. Nevertheless since, the current of men’s thoughts is led this way just now, and I see no evil in the current itself, I shall launch the bark of our discourse upon that stream, and make use of the fact, which I shall neither justify nor condemn, by endeavoring to lead your thoughts in the same direction. Since it is lawful, and even laudable, to meditate upon the incarnation of the Lord upon any day in the year, it cannot be in the power of other men’s superstitions to render such a meditation improper for to-day. Regarding not the day, let us, nevertheless, give God thanks for the gift of His dear Son.”
By contrast, Calvin seemed to unload both barrels on Christmas. Here is a quote from a sermon he gave on a Christmas day, cited from here
“Now, I see here today more people that I am accustomed to having at the sermon. Why is that? It is Christmas day. And who told you this? You poor beasts. That is a fitting euphemism for all of you who have come here today to honor Noel. Did you think you would be honoring God? Consider what sort of obedience to God your coming displays. In your mind, you are celebrating a holiday for God, or turning today into one but so much for that. In truth, as you have often been admonished, it is good to set aside one day out of the year in which we are reminded of all the good that has occurred because of Christ’s birth in the world, and in which we hear the story of his birth retold, which will be done Sunday. But if you think that Jesus Christ was born today, you are as crazed as wild beasts. For when you elevate one day alone for the purpose of worshiping God, you have just turned it into an idol. True, you insist that you have done so for the honor of God, but it is more for the honor of the devil.
Let us consider what our Lord has to say on the matter. Was it not Saul’s intention to worship God when he spared Agag, the king of the Amalekites, along with the best spoils and cattle? He says as much: ‘I want to worship God.’ Saul’s tongue was full of devotion and good intention. but what was the response he received? ‘You soothsayer! You heretic! You apostate! You claim to be honoring God, but God rejects you and disavows all that you have done.’ Consequently, the same is true of our actions. For no day is superior to another. It matters not whether we recall our Lord’s nativity on a Wednesday, Thursday, or some other day. But when we insist on establishing a service of worship based on our whim, we blaspheme God, and create an idol, though we have done it all in the name of God. And when you worship God in the idleness of a holiday spirit, that is a heavy sin to bear, and one which attracts others about it, until we reach the height of iniquity. Therefore, let us pay attention to what Micah is saying here, that God must not only strip away things that are bad in themselves, but must also eliminate anything that might foster superstition. Once we have understood that, we will no longer find it strange that Noel is not being observed today, but that on Sunday we will celebrate the Lord’s Supper and recite the story of the nativity of our Lord Jesus Christ. But all those who barely know Jesus Christ, or that we must be subject to him, and that God removes all those impediments that prevent us from coming to him, these folk, I say, will at best grit their teeth. They came here in anticipation of celebrating a wrong intention, but will leave with it wholly unfulfilled.”
So what I’m looking for is men who have spent time laboring to refute Spurgeon and Calvin on their points.
