The has been much written on Facebook and many Christian/Reformed blogs about the Christmas holiday and its observance. Several seem to have an erroneous understanding of Reformed church history. Allow me to direct you to a a post by Danny Hyde of Oceanside United Reformed Church which unscrambles some of these misconceptions.
Most often than not, the charge is that observing any days other than the Lord’s Day is a violation of the Reformed regulative principle of worship. This principle comes from the second Commandment, which teaches, “That we in no wise make any image of God, nor worship Him in any other way than He has commanded in His Word” (Heidelberg Catechism, Q&A 96). However, ...The purpose of these festivals was twofold: to increase godliness by means of meditating upon the work of Christ and to give thanks for this work.
After dealing with some historical documents and quoting some well known theologians, Hyde concludes with four excellent reasons why we can and should observe these holidays provided it is done so properly. Read the post here and learn how we can enjoy these holidays and honor our Lord and Savior.
