In Worship As Theology , Don Saliers discusses how worship is both theological (God-centered) and anthropological (embodied and embedded in specific human and cultural contexts). He illuminates worship as a theology "prayed, sung, and enacted." At the same time--by focusing upon specific dimensions of liturgical action such as praising, thanking, invoking, confessing, proclaiming, interceding, and blessing--he addresses the differences between the liturgical/sacramental and the "free-church"/evangelical church traditions. Underlying Saliers' approach is his basic conviction that Christian liturgy is an eschatological art. Theological integrity in worship, he asserts, calls for a permanent tension in the forms and patterns which reflect the "already" and "not yet" of Christian life in the world for the sake of the world. Worship As Theology , therefore, begins and ends with the eschatology of the divine promise, that the church's cry is still "Come, Lord Jesus!" and that God's will be done on earth "as in heaven."
