Tlaloc, I think you'll find the new teaching article on the family as a Christian Assembly, a church, to be very interesting. The old school Calvinists, the Puritans like Cotton Mather, Covenant theologians like Herman Witsius who wrote The Economy of the Covenants Between God and Man, and Jonathan Edwards saw the Christian Assembly in a different way. They saw the covenant made between a man and woman establishing a church there with the man as the overseer and the woman as the helpmate and then their mission was ordained of God to be a missiological entity that should go forth with the great commission. To them a covenant theology meant that when two people came together like that it was indeed a church in small form.
