Baha'is must not have any affiliations with churches

• Bahá’ís Must Have no Affiliation with Churches
• In other words, there is no Christian church today whose dogmas we, as Bahá’ís, can truthfully say we accept in their entirety—therefore to remain a member of the Church is not proper for us ...
• … No Bahá’í can any longer dissimulate his faith and practise the laws and ordinances of a previous dispensation and call himself at the same time a believer.
• "If a person is registered as a member of a church or similar religious organization he should withdraw from it on becoming a Bahá’í.
• "In the case of new believers, it should be made clear to them in the course of teaching them the Faith that one cannot be a Bahá’í and also a member of another religious organization.
• If a believer (does not resigns from his former church) and remains adamant the Baha'i institutions are ordered to consider depriving him of his voting rights.
• "we do not and cannot support, church institutions and doctrines when Christ has come again and brought new laws for the world today ...
• [he should] "write a letter to the appropriate authority in this synagogue, explaining that he is a practicing Bahá’í, but is keeping his synagogue membership for the benefit of his [Jewish] wife and children…"
• Two Bahá’ís, when getting married, cannot have the religious ceremony of another Faith.
• "As to the age of maturity, voting rights in the Bahá’í Administrative Order are acquired when a believer becomes 21 and you might well make that point the period for severance of those religious ties which members of the Bahá’í community cannot maintain. The main point is that while, for the sake of family unity, the concession has been made to youth on the matter of withdrawal from church membership, every effort should be made to encourage all believers, as well as Bahá’í youth, to observe requirements of Bahá’í membership even at the cost of some hardship or inconvenience."
• Baha'is should not pay Church Tax.
