Confessionalism

From ReformedWiki.org, the wiki for Reformed Christianity

Confessionalism is a belief in the importance of full and unambiguous assent to a Confessions of Faith, which followers believe to be reliable and accurate summaries of the teachings found in Scripture. Confessions of Faith also demonstrate theological distinctions from other groups of Christians. Confessionalism asserts that differing interpretations or understandings, especially those in direct opposition to traditionally held teachings, cannot be accommodated within a church communion. A denomination or church that shares these beliefs can be called a confessional denomination or confessional church, respectively.
