ACLU Judges Nativity Scene as "Non-Biblical," Drops Lawsuit
Here are a few quotes from men God used to rid us of the tyranny that is Rome:
“God not only rejects all invented manners of worship but strongly abominates them. It must be said, in fact, that as soon as men seek to worship God by their own judgment, whatever they produce is foul profanation.” (John Calvin)
“With respect to ceremonies and above all the observance of holy days: although there are some who eagerly long to remain in conformity with such practices, I do not know how they can do so without disregard for the edification of the church, nor how they can render an account to God for having advanced evil and impeded its solution.” (John Calvin)
“Long before the fourth century, and long before the Christian era itself, a festival was celebrated among the heathen, at that precise time of the year, in honour of the birth of the son of the Babylonian queen of heaven; and it may be fairly presumed that, in order to conciliate the heathen, and to swell the number of the nominal adherents of Christianity, the same festival was adopted by the Roman Church, giving it only the name of Christ.” (Alexander Hislop)
“If it had been the will of God that several acts of Christ should have been celebrated with several solemnities, the Holy Ghost would have made known to us the day of his nativity, circumcision, presentation at the temple, baptism, transfiguration, and the like.” (David Calderwood)
“The keeping of some festival days is set up instead of the thankful commemoration of Gods inestimable benefits: howbeit the festivity of Christmas has hitherto served more to Bacchanalian lasciviousness than to the remembrance of the birth of Christ.” (George Gillespie)
“If Paul condemns the Galatians for observing the feasts which God himself instituted [But were now abrogated], and that for his own honour only, and not for the honour of any creature: the Papists are much more laid open to condemnation, which press observations of feasts of mens devising ” (Thomas Cartwright)
“THERE is no day commanded in scripture to be kept holy under the gospel but the Lord’s day, which is the Christian Sabbath. Festival days, vulgarly called Holy-days, having no warrant in the word of God, are not to be continued.” (Westminster Directory for The Publick Worship of God)
