Good; now we have something to build on.
We both agree that the MANNER has something to do with it.
Now then, does our present MANNER of Christmas celebrating emulate the MANNER of the people who worshiped idols?
Yes, it does. It was many years ago now that I had a neighbor who was fascinated with mysticism and paganism which included the study of Christian beliefs. Not that he practiced it but just studied it as it related to beliefs and practices. He laughed at the duplicity of Christians with their incorporation of paganism. It was the first time I had to face what he was showing me. That was back in the early 80s. It forced me to understand if I was ever to witness to him or anyone with his understanding of paganism.
To say I was shocked at what I learned is an understatement. He and I spent many hours studying scripture together. Today he is a solid God fearing follower of Christ and can not be shaken. God sent him into my life and me into his.
