Four talks by controversial US Catholic preacher Jason Evert this week have been cancelled after concerns were raised about his views on homosexuality and contraception.

Mr Evert is founder of the Chastity Project, which promotes chastity among young people. In his book ‘Pure Manhood’ Mr Evert wrote that “the homosexual act is disordered, much like contraceptive sex between heterosexuals. Both acts are directed against God’s natural purpose for sex - babies and bonding.”
