Elsewhere in the policy, it stated: "'Sexuality' is defined in this document as the capacity to love and procreate"; "sexuality has been distorted and diminished"; "natural methods of family planning respect the dignity of the married couple"; and that the school's aim is to ensure pupils "learn the reasons for delaying sexual activity and for restricting sexual activity to marriage".

Last week, a former pupil wrote about the policy anonymously on a blog entitled Faith Schoolers Anonymous condemning the phrase "cannot approve of homosexual genital acts" as "a derogatory, and frankly disgraceful term to use in describing people’s ‘personal relationships’, which does nothing to instil any confidence in pupils and parents that the Church does in fact ‘recognise the dignity of all people’ or ‘affirm the homosexual as a person’, as the same policy claims."

The writer continued: "The school then goes on to dictate its opinion on same-sex marriage, asserting incorrectly that ‘English law’ reflects the Church’s opinion that 'a homosexual partnership and a heterosexual marriage can never be equated'."

Since the introduction of the Marriage (Same Sex Couples) Act 2013, all marriages stand equally before the law in England and Wales.

The Equality Act 2010 also prohibits discrimination on the grounds of sexual orientation and guidance from the Department for Education to faith schools on implementing the act warns: "If a school conveyed its belief in a way that involved haranguing, harassing or berating a particular pupil or group of pupils then this would be unacceptable in any circumstances and is likely to constitute unlawful discrimination."

With regards to teaching about marriage the guidelines advise: "Schools must

accurately state the facts about marriage of same-sex couples under the law of England and Wales... Teaching about marriage must be done in a sensitive, reasonable, respectful and balanced way."
