See this article: "cultural celebrations are permissible observances for individual Christians, but they represent an unwarranted intrusion when they are introduced into the ministry and services of the local congregation ... [eg festooning evergreens with lights and ornaments, fashioning garlands of tinsel and holly] ... they are nowhere authorized by Christ or His apostles for inclusion in the leitourgia of the church ... I enjoy all the bric-a-brac of tinsel and trees, logs and nogs, candles and candy canes. But I do not worship those things. I worship the incarnate Lord Jesus Christ. Worshipping Him must be set apart—sanctified—from those other enjoyments or it simply becomes profane."
