Why is it important to you for you to need a direct command "in the way that Paul states to keep observing his death, until he arrives" regarding Christmas?
LOL!!!!!!
First off, what you are saying, and I am asking has nothing to do with JWs, nor wedding anniversaries. And for the record, I do not celebrate christmas or wedding anniversaries.
And I take it that you are unable to cite ANY Scripturally support to observe Jesus' birth like there is in regard to his death.
The reason it would be important to have such a direct command is because if it was something that Jesus wanted his followers to do then he would have made it clear to them to do so the way he did in regard to his death.
You said:
surely you have heard of Christmas? It's the greatest holiday the world has ever known
It is 'the people of the world' that came up with 'christmas', not Jesus. If that is the case, then are those that celebrate 'christmas' following Jesus or 'the world'?
