I think pagan in a religious sense means prior to Christianity. Not all things pagan are bad.
People have to decide for themselves which days or customs to obeserve and this decision is based on their own consciences.
From a Christian point of view, this is actually a biblical also. Paul points this out in Romans 14. What I found interesting with this chapter since leaving the WT is the realization that it is the person(s) who are fearful of observing certain days, thinking they will offend God by it that Pauls calls "weak in the faith". Those stronger in the faith understand that we are free to observe all days and customs as long as we do it 'unto the Lord" and do not use this time for an excuse for misconduct.
Now, DubR, I am of course not applying this to you, only to my fellow believers. So please do not take offense. However, you should know that in "real" Christianity we are as free to use our conscience in observing certain days as you are as a non believer. That is people cannot lump all Chrisitans into the same pot.
Its funny because the WT's view of pagan days and that Christians should not observe them does not hold up to bible scrutiny. It is just their narrow view and one way they purposely seperate themselves from fellow believers. Peace, lilly
