God had ordained what days are ordinary, and which days He had made High Days and hallowed them as feast days for the Israelites. Many generations have strayed away from the way they are suppose to serve God; they have taken heed to the way of the stranger, celebrating man's pagan holidays. We have to serve God the way we are ordained to and not the way we want to. There are man's philosophies and opinions, and then there is the truth. (Ecclesiasticus 33: 7-9)
