I don't have any comments to make on this fact myself, beyond simply remarking that Christian celebrations have often blended with Pagan celebrations, and in effect baptized them. The thing to remember above all else is Paul's admonition that blessing and eating meat that had been an offering to a dead stone or wooden idol was in no wise a sin. The fact is, the idol is not real. It is unable to eat. If the early Christians bought the meat at a discount after it had been offered to idols, then they were welcomed to say a blessing for it and eat up, knowing it was just meat. Likewise, holidays are put to use in various ways by different people in the world. Though I have had the "Holiday Police" attempt to hand me photocopied information on the origin of "pagan holiday practices" like Christmas trees, I know that Apostle Paul said the manner in which I esteem the ritual is what really matters. So, we know that what may be perfectly fine for me, such as a Christmas tree, may be a problem for you, if you would worship the tree. I hope not. But, I suppose some people do feel worshipful about trees.
I love nature myself. I just don't fit into the category of "tree-hugger," since I see trees as fit for natural resources, and suitable for shade, home building, and recreation alike. Likewise, I don't worship the saints from ages past, as set forth by some church traditions. Yet, I see the truth in recognizing the sacrifices of the martyrs and Christians who preceded us in this faith. What is missing to me, though is the correlation of All Souls day to the church today.
All Saints Day is traditionally on November 1st, and All Souls is on the 2nd. On All Saints we celebrate the Saints as I have mentioned. But, on All Souls, we pray and do penance, or something of the sort, for those who have died and are "stuck" in purgatory. I don't believe in the existence of a purgatory, and I certainly can't see a point in recognizing the date. But, I suppose, the important thing to ask yourself is, "What does the day mean to me?" Jesus taught a religion of the heart. This had been the intent all along, but the Jews had digressed to the point of effecting a myriad of laws to enforce adherence to these heart laws. Jesus merely pointed out that He wanted heart service and not lip service.
Today is All Saints day. I ask myself who are the people in my life and my past who have helped me in my faith? And, I try to reach for the essence of the faith they held, carrying it high like a torch to light my way.
