The openly gay Lord of the Rings actor, 68, objects to a verse in the book of Leviticus which states that men who sleep together will be put to death.
He said: "It's the one thing I find difficult to defend but do go on doing."
Leviticus 20:13 reads: "If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death. Their blood shall be upon them."
