That All May Believe brings an evangelical catholic theological perspective to bear on controversial issues having to do with the truth of the gospel, the ecumenical quest for church unity, and the encounter of Christianity with other world religions. Here Carl Braaten argues and demonstrates that a theology may be evangelical without being Protestant, catholic without being Roman, and orthodox without being Eastern. Written from a Lutheran perspective, it is nonetheless a work postdenominational in scope and substance. In sharp contrast to the older style of doing theology to bolster a particular denominational tradition or the newer style that revises the Christian faith to conform to modern culture, the ecumenical orthodoxy that emerges here does theology out of the common biblical and creedal mainstream of the Christian tradition. Braaten focuses on the core of Christianity 2; faith in Jesus Christ according to the scriptures. He applies the criterion of Christ to many questions of Christian theology today, pointing the way to a more complete and foundational theology for every modern Christian.
