It's not about Santa Claus or "a season of peace."
It's about a great gift and sacrifice that God gave, to show his children a way back to Him from this world of sorrow and venality.
We don't exchange gifts because of gold, frankincense and myrrh. We exchange gifts in echo of His gift, which is our salvation.
Christmas is a season of hope, symbolized in the light of the star that led the wise and the humble to Bethlehem, as Christ's message is a light to lead us all to God.
