No one is saying it's okay to promote a lie! I think that in the nativity scenes, we are trying to portray all the meaningful parts of Christ's birth. The wise men were not present at Jesus' birth, but His birth was the sign that they had been watching for and seen. It was the star of His birth that prompted the wise men to make their journey to come and worship Him. So, I believe it's not a lie to link these magi to one of the most important events in our history.
I do understand the need to be careful about what Christians accept. To often I think that we allow society values to slip into our celebrations. A pastor that I like to listen to says this about the world we live in...we can do three things: reject it, accept it or redeem it. Some things are fine for Christians to join in with; they don't compromise our faith or our values. Some just need to be rejected outright...there is nothing about it that can be good for us or for God's glory. But there are so very many things in this world that can be redeemed by us. The internet is used by some for very worldly causes, but it can also be used by us to spread the gospel! When it comes to Christmas, I don't think that it hurts for us to give gifts to others, to appreciate that it's family time. It helps remind us of the best gift of all...Jesus. It helps us remember that we're all a part of God's family through Christ. But if we ever loose sight of the true meaning of Christmas, then we've lost it. Does it matter what day the Lord was actually born on? Given that we can't really know, I don't think so. But setting aside a day every year, and remembering the wondrous event of His birth, that's a special day, and I can't imagine celebrating it in a better way then giving to others and spending time with my family...biological one and the spiritual one too!
So now I seem to be accused of wanting to eliminate the wise men from the Christmas story, I guess I am missing something here, I started this post by mentioning that the wise men were not in attendence at Jesus birth, I agree they are, and should be, included in the story of his birth but not at the time of his birth, and I am not against setting aside a day regardless of the date to celebrate Christ's birth even though the bible never instructs us to do so...I'm sorry I decided to mention that the Nativity displays of today give the impression the wise men or Magi were there....Please forgive me.
