In early Christianity and the New Testament, "faith" assumed a central role, presumably because faith "was discovered in an as-yet unknown manner" (Hans Weder). In New Testament studies, the topos of faith is experiencing a minor renaissance. Yet with faith, early Christianity also discovered doubt. It was not sought, but it was surely found. Doubt and its companions attach themselves "parasitically" to faith. Doubt belongs to faith, but cannot exist without it. As surely as there was no unified concept of "faith" in early Christianity, there was also no unified concept of "doubt". We ought rather to reckon with a multiplicity of forms of expression of doubt through which the concrete intellectual, emotional, and ethical dissonances in the world of meaning of individual believers and/or groups of believers come to expression.
