"Remember the Sabbath day, to keep it holy.  Six days you shall labor, and do all your work, but the seventh day is a Sabbath to the LORD your God..." (Exodus 20:8-10).
"Do not think I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them" (Matthew 5:17).
Recently, our church began to study the Puritans, a group of early Protestants in England who were not satisfied with merely reforming the order of the church, but were chiefly concerned with inward holiness of her members.  Many Puritans were later to move to the New World and begin their religious advancement of a pious society in New England (not for freedom of religion, which is more commonly stated).
