From this Saturday, gay and lesbian couples in England and Wales will be able to get married in a civil ceremony.
Rev Andrew Cain, of St Mary's Kilburn and St James' West, in north London, says he is prepared to defy a Church of England ban on the blessings of same-sex marriages.
But Rev Steven Hanna, of St Elisabeth's Church, Dagenham, says: "I see it as inconsistent that a clergyman can choose to bless something that God himself has not blessed."
