Then as I became involved in the process of becoming a priest and, later, being a priest, I was always aware that the "Christmas" that most people celebrated seemed to quite different from the religious or spiritual event that I was focused on. I was not terribly involved in the "human" aspects of the celebration until later when I started to become aware that the "human" dimensions could also be "spiritual".
When I became a parent, Christmas took on the perspective of seeing Christmas from the eyes of my children. Admittedly, they and, surely my wife who has always been big into Christmas, helped transition me into the positive aspects of the "holiday".
During the years, the actual religious dimensions of Christmas transitioned from the childhood beliefs of the Christmas story as literally true through all sorts of migrations based on the biblical research that was available.
And, then, the whole religious support system was buried by the inescapable conclusion that Christianity itself was no more that any religious structure designed to provide a support system to those trying to cope with the mysteries of life, especially death.
Now, Christmas has become a human event, period, which may provide some "spiritual" insights into our better selves, e.g., it is great to be with family, to experience the bonds developed by our history, to share the stories that have come to make us who we are.
From my perspective, I experience this human event endlessly throughout the year. When I am with any of the children and family, I am totally aware of the wonder of the experience that I could belong to such beautiful people. When I see my children as dedicated to their spouses and children, I am experiencing the beauty of love being shared, as is often referenced by Christians who see in Jesus the love that God has for mankind. And when I see my grandchildren experience life with such enthusiasm, I can only be awestruck that our history will continue to develop more stories of love, dedication, and hope.
