Liberal Christianity, also known as liberal theology, covers diverse philosophically and biblically informed religious movements and ideas within Christianity from the late 18th century onward. Liberal does not refer to Progressive Christianity or to a political philosophy but to the philosophical and religious thought that developed and grew as a consequence of the Enlightenment.
Liberal Christianity, broadly speaking, is a method of biblical hermeneutics, an undogmatic method of understanding God through the use of scripture by applying the same modern hermeneutics used to understand any ancient writings, symbols and scriptures. Liberal Christianity did not originate as a belief structure, and as such was not dependent upon any Church dogma or creedal doctrine. Unlike , liberalism has no unified set of propositional beliefs. Instead, "liberalism" from the start embraced the methodologies of Enlightenment science, including empirical evidence and the use of reason, as the basis for interpreting the Bible, life, faith and theology.
The word liberal in liberal Christianity originally denoted a characteristic willingness to interpret scripture according to modern philosophic perspectives (hence the parallel term modernism) and modern scientific assumptions, while attempting to achieve the Enlightenment ideal of objective point of view, without preconceived notions of the authority of scripture or the correctness of Church dogma. Liberal Christians may hold certain beliefs in common with Roman Catholicism, Orthodox Christianity, or even fundamentalist Protestantism.
The theology of liberal Christianity was prominent in the Biblical criticism of the 19th and 20th centuries. The style of Scriptural hermeneutics (interpretation of the Bible) within liberal theology is often characterized as non-propositional. This means that the Bible is not considered a collection of factual statements, but instead an anthology that documents the human authors' beliefs and feelings about God at the time of its writing, authors influenced by their own historical and cultural context. Instead, liberal Christian theologians have an allegorical interpretation of the Bible which emphasizes the moral or other spiritual lessons which can be learned from its stories.
