Bishop Greg O'Kelly is one of a number of clerics who have spoken out against same-sex marriage in response to recent moves to legalise it in Australia.
Bishop O'Kelly wrote to his parishioners saying that comparing same-sex and heterosexual relationships was like comparing apples and pears. "The nature of a marriage between two same-sex people and the marriage between a man and a woman open to life ... are two very different things," he wrote.
"A pear is not an apple, no matter what you say, even if you start to redefine the term from its traditional one, it doesn't alter the reality."
Bishop O'Kelly's letter said that children of homosexual couples would feel like a Stolen Generation. "Can't you imagine a situation that when there's a falling-out between a child and a parent, as can happen, that'll be one of the lines they use?" he wrote.
"You deliberately intervened so that I would not have a father present in my upbringing, or not have a mother present in my upbringing."
