Marriage in the end is a civil contract.
Every wedding has the celebrant, minister or whatever silly hat wearing person who runs the show, have the Happy couple & witnesses sign legal documents. The wedding is NOT legal until those documents are signed, witnessed & lodged at the appropriate Government registry. The show in a church wedding, or anywhere else, means NOTHING in law. Its all about the civil contract signed by the participants & those being registered.
The brain damaged lobby voting no simply miss the whole point & are happy to 'mystify' the whole affair to suit their own hateful agenda.
God save their vicious & damaged souls.
