In the 19th century, primarily in Protestant groups, a new kind of systematic theology arose that attempted to demonstrate that Christian doctrine formed a more coherent system premised on one or more fundamental axioms. Such theologies often involved a more drastic pruning and reinterpretation of traditional belief in order to cohere with the axiom or axioms. Friedrich Daniel Ernst Schleiermacher, for example, produced "Der christliche Glaube nach den Grundsätzen der evangelischen Kirche" ("The Christian Faith According to the Principles of the Protestant Church") in the 1820s, in which the fundamental idea is the universal presence among humanity, sometimes more hidden, sometimes more explicit, of a feeling or awareness of 'absolute dependence'.
