that "A Scout is reverent towards God. He is faithful in his religious duties. He respects the beliefs of others." The BSA 2019 Guide to Advancement states: Beyond these requirements, the BSA does not require adherence to particular Christian religious beliefs. Buddhists, followers of Native American religions, Muslims, Jews, Christians of all denominations, and many others, including those who define their own spirituality, can be and are members of the BSA. The BSA recognizes religious awards for about 35 faith groups including Islam, Judaism, Baháʼí, Zoroastrianism, Hinduism, Sikhism and 28 varieties of Christianity. Boy Scouts of America–approved religious emblems exist for a number of religions, while other emblems remain unrecognized by the BSA. In regard to Unitarian Universalism, the BSA has had a history of disagreements with the Unitarian Universalist Association (UUA), dating back at least to 1992 when the UUA stated its opposition to the BSA's policies on homosexuals, and atheists. In March 2016, following a change of BSA policy regarding homosexuality, the BSA signed a new Memorandum of Understanding (MOU) with the Unitarian Universalist Association (UUA). The MOU gives any Unitarian Universalist congregation the authority over all phases of the program that affect the spiritual welfare of those who participate. As part of the agreement in the MOU, the religious emblems developed by the Unitarian Universalist Association were reinstated as of May 2016. Under the terms of the MOU, the UUA has said that "when a Unitarian Universalist community charters a Boy Scout unit, religious teachings will remain firmly rooted in Unitarian Universalist theology," while also saying that "The UUA, even while moving with gratitude into this new relationship with the Boy Scouts of America, recognizes that the BSA's requirement for scouts and leaders to affirm a religious belief is at odds with our noncreedal faith tradition. The UUA will continue to work to move the BSA toward greater inclusion." The Secular Coalition for America has urged Congress to revoke the federal charter of the BSA, stating: "Our government must not entangle itself in religious organizations; nor should it establish, with government imprimatur, a private religious club." In 2000, the House of Representatives rejected a bill proposing the revocation of the BSA's federal charter by a 362-12 vote, with 216 Republicans, 144 Democrats, and two independents voting against.
