Book excerpt: Pro Ecclesia is a quarterly journal of theology published by the Center for Catholic and Evangelical Theology. It seeks to give contemporary expression to the one apostolic faith and its classic traditions, working for and manifesting the church's unity by research, theological construction, and free exchange of opinion. Members of its advisory council represent communities committed to the authority of Holy Scripture, ecumenical dogmatic teaching and the structural continuity of the church, and are themselves dedicated to maintaining and invigorating these commitments. The journal publishes biblical, liturgical, historical and doctrinal articles that promote or illumine its purposes.
