This essay argues that the American psychologist and philosopher William James should be viewed in the Lutheran Reformation’s tradition because this viewpoint offers the hermeneutical key to his philosophy of religion. Though James obviously didn’t ascribe to biblical authority, he expressed the following religious sensibilities made possible by Martin Luther and his contemporaries: 1) challenge of prevailing systems, 2) anti-rationalism, 3) being pro-religious experience and dynamic belief, 4) need for a personal, caring God, and also 5) a gospel of religious (...) comfort. This essay asks, in one specifi c form, how religious concerns can hold steady over time but cause very different expressions of faith. (shrink)
