Non-denominational churches are not formally aligned with, or part of, any specific Christian denomination.
While the notion of non-denominational churches date back to the 1800s and the Restoration Movement, which supported “no creed but Christ,” the widely used “non-denominational” term sprang up in the U.S. in the latter part of the twentieth century. Its emergence attracted followers who were looking to avoid the trappings of rigid dogmas of mainline denominations.
