A number of senior religious leaders have signed a statement declaring support for same-sex marriages taking place on 29 March 2014.
"We rejoice that from tomorrow same-sex couples will be able to marry in England and Wales," they say.
A press conference and photo-call is being held at Friends House in central London this morning (28 March).
The statement continues: "As persons of faith, we welcome this further development in our marriage law, which has evolved over the centuries in response to changes in society and in scientific knowledge.
"We acknowledge that some (though not all) of the faith organisations to which we belong do not share our joy, and continue to express opposition in principle to such marriages. We look forward to the time, sooner rather than later, when all people of faith will feel able to welcome this development."
