Unitarian Universalism (sometimes called "Unitarianism") is an interfaith church) which draws its name from an interfaith concept of "unitary God" (as opposed to an exclusively Christian concept).
Note:Some authors use the word "unitary" synonymously with unital, which for a module implies the underlying ring has multiplicative identity which acts as the identity on it, and for an algebra implies that the algebra itself has a mutliplicative identity.
