Articles: Schools and Religion

Article 26 of the Universal Declaration of Human Rights (UDHR) identifies the right of every child to an education, and that right to an education be directed toward “the full development of the human personality and to the strengthening of respect for human rights and fundamental freedoms.”
The United Nations' Special Rapporteur Karima Bennoune has recommended that states provide for the separation of religion and state to help counter religious extremism. Her report on  protecting cultural rights, for the UN Human Rights Council, warned of "rising tides of fundamentalism and extremism" that "represent major threats to human rights worldwide".
Religious organisations are classified as 'charities' in Australia, whether they engage in charitable works or not. This means they are automatically tax-exempt, in both their religious and commercial activities. Is it possible that the revenue of the tax-exempt churches that stand behind religiously based schools, together with the revenue of these tax-exempt schools, is more than enough to fund them?
