QUOTE : Catholic social theory is based upon reason in conversation with faith. Its basic category is the common good. It presupposes the God revealed by Jesus Christ, who became one of us in order to bring us under God’s sovereignty. God’s eternal Kingdom is made present now in the Church, the sacrament of God’s Kingdom, through which God acts surely and visibly. But God acts through and in all created reality. Just as religion is less a set of ideas than a vehicle for relating to God, the Church is less one more institution within a state than an instrument for relating each of us and the whole world to God.
