You have spoken really well Mz, as followers of Christ we are to share and show love and kindness at every given opportunity and we can also create that opportunity too.
Christmas is a feast made by man, yes, we were told that it is the mass of Christ but then it is something that our master himself did not observe and even his apostles, so why then do we that the gospel was passed down to want to do what was not written?
The Bible told us in 2 John 9 that he that abides in the doctrine of Christ has both the father and the son but he that does not abide in the teachings (doctrine) of Christ has not the father.
You are child that I believe has the grace to understand the words of God and that's why I'm trying my best to explain further to you but please don't think I'm saying we shouldn't be kind or share love, no that's not what I'm saying, I'm only saying that if December 25 is a special day to do all that then how does that portray what the Bible teaches?
We are to love and be kind everyday of our lives until the day we die. Christ said we should do the lord's supper to remember him and what he has done for us, which is what John 3:16-17 said, we are doing the lord's supper to remember his birth, death, burial and resurrection so what's the need for another feast especially when our master never asked us to do so or even showed us an example of such act?
Christmas is a strange feast to the Holy scriptures, we never saw any of it's practices anywhere in the Bible so why should we as Christians partake of it? Like I said, it matters how we worship God, if we do anything as we like then we will get it wrong because like the book of Isaiah 55:9 said, that just as the heavens are higher than the earth, so are the ways of God higher than our ways. Please, I'm not sure if I said that passage right, I will check soon.
