Denominationalism is the division of one religion into separate groups, sects, schools of thought or denominations. Denominationalism as an ideology which views some or all Christian groups as being, in some sense, versions of the same thing regardless of their distinguishing labels, is not accepted by all Christian churches. The Catholic and Orthodox Churches do not use this term as its implication of interchangeability does not agree with their theological teachings. Denominationalism is a largely Protestant concept among Christians.
