Why do so many christians in America keep sunday as the day of rest? I know that somewhere in hisstory the catholics changed the sabbath day to sunday, does that mean that sunday worship christians are worshiping in vain? My mother raised us as pentecostal and she walks a very straight line when it comes to her faith in God, and I have been a witness to the power of her prayer in peoples lives especially my own but she does not keep the sabbath. At this moment I do not visit any church because I find my self at the cross roads of these two days.I have read alot of literature about the Christian sabbath and what goes along with christians who keep it like not celebrateing Christmas and not eating certain foods ect. So bottom line is does God acknowledge you as a Christian regardless of the day you keep?
