Non-denominational

A non-denominational person or organization is not restricted to any particular or specific religious denomination. 
Overview.
The term has been used in the context of various faiths including Jainism, Baháʼí Faith, Zoroastrianism, Unitarian Universalism, Neo-Paganism, Christianity, Islam, Judaism, Hinduism, Buddhism and Wicca. It stands in contrast with a religious denomination. Religionists of a non-denominational persuasion tend to be more open-minded in their views on various religious matters and rulings. Some converts towards non-denominational strains of thought have been influenced by disputes over traditional teachings in the previous institutions they attended. Nondenominationalism has also been used as a tool for introducing neutrality into a public square when the local populace are derived from a wide-ranging set of religious beliefs.
