Infidel

An infidel (literally "unfaithful") is a person who is accused of disbelief in the central tenets of one's own religion, such as members of another religion, or irreligious people. Infidel is an ecclesiastical term in Christianity around which the Church developed a body of theology that deals with the concept of infidelity, which makes a clear differentiation between those who were baptized and followed the teachings of the Church versus those who are outside the faith. Christians used the term infidel to describe those perceived as the enemies of Christianity. After the ancient world, the concept of otherness, an exclusionary notion of the outside by societies with more or less coherent cultural boundaries, became associated with the development of the monotheistic and prophetic religions of Judaism, Christianity, and Islam (cf. pagan). In modern literature, the term infidel includes in its scope atheists, polytheists, animists, heathens, and pagans. A willingness to identify other religious people as infidels corresponds to a preference for orthodoxy over pluralism.
