It would require a positive command from the Word of God in order to consider it legitimate.
"We have no superstitious regard for times and seasons. Certainly we do not believe in the present ecclesiastical arrangement called Christmas. First, because we do not believe in the mass at all, but abhor it, whether it be sung in Latin or in English. Secondly, because we find no Scriptural warrant whatever for observing any day as the birthday of the Savior; and consequently, its observance is a superstition, because not of divine authority." (CH Spurgeon)
Ok, just so I'm clear:
The Word of God isn't going to change and you presently do not know of (or do not so interpret) anything in the Word of God that lends any legitimacy to a Christmas Eve service, no matter what the service content or no matter any revival throughout the remainder of the year.
Right?
Nothing could ever legitimize any Christmas eve service, in your view?
So TC, what are you going to do on Christmas eve?
This thread is not about "proper" Christmas celebrations or non-celebrations. Knock it off.
