A final requirement is that the candidate professes to adhere to a mainstream Christian faith, assert that it is the best of all possible religions, and swear never to abandon it. If the Christian belief of the candidate is in doubt, a birth certificate may be requested; in the Scandinavian countries, birth certificates contain a field for religion. Owing to the religious history of the Scandinavian nations, Swedish Rite Freemasonry has strong connections with the various national Lutheran churches, which are the majority churches of all the Swedish Rite nations. However, members of any Trinitarian Christian denomination are accepted into membership. Membership of certain sects which are unrecognised by the World Council of Churches does not qualify a candidate for membership of the Swedish Rite; these include the Mormons, the Unification Church (the Moonies), and Jehovah's Witnesses.
