To contemporary minds, the notion of justice toward God is seldom considered and often foreign. Far more discussed is how God might either undermine or motivate social justice. The Primacy of God offers an important intervention. With the aid of St. Thomas Aquinas, Staudt argues that it is vital for both contemporary society and contemporary Catholic theology to return to the traditional view of God as the one to whom all human and social action must be ordered and to recover the virtue of religion as the virtue which orders all other virtues to God. Not only does Staudt helpfully remind readers of the ancient philosophical and biblical notion of worship as a dictate of the natural law, he also illuminates the way in which Christian liturgy, as an enactment of Christ's high priesthood, is the great fulfillment of natural and biblical worship. Accordingly, Staudt secures religion as essential for the virtue of love. This brings Staudt to criticize modern theologians like Karl Barth, who claimed that religion is inherently idolatrous, as well as Karl Rahner, who claimed that love of neighbor is the highest moral act. Staudt also considers the question of religious truth in light of the plurality of religions, soliciting the assistance of Hans Urs von Balthasar and Joseph Ratzinger, as well as the way in which religion relates to the development of culture, engaging the great Catholic social historian Christopher Dawson. The Primacy of God is a much-needed work that ought to set the agenda for Catholic theology in the twenty-first century.
