Instead, by engaging in worldly employments and recreations, I will not treat that day as holy. This is my Christian liberty, as Paul explained:
Romans 14:6 He that regardeth the day, regardeth it unto the Lord; and he that regardeth not the day, to the Lord he doth not regard it. He that eateth, eateth to the Lord, for he giveth God thanks; and he that eateth not, to the Lord he eateth not, and giveth God thanks.
Rome has tried to bind the consciences of its members by employing, for example:
Canon 1246(emphases added)
1. Sunday is the day on which the paschal mystery is celebrated in light of the apostolic tradition and is to be observed as the foremost holy day of obligation in the universal Church. Also to be observed are the day of the Nativity of Our Lord Jesus Christ, the Epiphany, the Ascension and the Most Holy Body and Blood of Christ, Holy Mary Mother of God and her Immaculate Conception and Assumption, Saint Joseph, the Apostles Saints Peter and Paul, and finally, All Saints.
On Sundays and other holy days of obligation the faithful are bound to participate in the Mass; they are also to abstain from those labors and business concerns which impede the worship to be rendered to God, the joy which is proper to the Lord's Day, or the proper relaxation of mind and body.
As explained at the link (link), "Since a 'grave cause' is needed to excuse one from this obligation it would be a serious or mortal sin to willfully skip Mass on Sunday or a Holy Day of Obligation, as the Church has always taught." Thus, Catholicism legalistically seeks to bind the consciences of its members to observe holy days that Scripture does not require.
In fact, Scripture gives Christians the freedom that I will (Lord Willing) be exercising to use the day for God's glory through an absence of regard for the day. I would like to encourage my readers to consider doing the same.
Don't get me wrong, if you choose to celebrate Christ's birth tomorrow, there is nothing inherently or intrinsically wrong with that. It is also your liberty to do so, and I won't tell you that it is a serious sin to do so. That's the other side of the Romans 14:6 coin.
Whether you choose to celebrate Christ's birth or not, may December 25, 2008, find you being edified and grown up in the knowledge of the Incarnate Word.
