"See what love the Father has bestowed on us that we may be called the children of God."
1 John 3:1
This passage from the first letter of John was in the first reading today. How appropriate it is that during the Christmas season when we celebrate the birth of God's Son, we also celebrate our own creation as children of God. And we are all children of God. God created each and every one of us.
It is so easy here on earth to get caught up in our differences, whether they be of color, religion, economic status, nationality, etc. But God sees us all as his children (unruly children, perhaps?) and we are all brothers and sisters in the Lord. So, we should treat each other as such. Now, this doesn't mean we will always get along - who among you gets along with your biological siblings all the time? - but we should treat each other with love and respect. The world would be a much better place for it.
