Dear Josephus,

«Are we to define their relationship as a human union of marriage?»

What business of us is to define other people's relationships? Let them define it for themselves any way they like!

Yuyutsu,
The fact is it is the State that represents all people who will define what is marriage not the persons themselves. We will then have to call their relationship marriage not just the two persons. It will be enforced upon society to recognise that they are legally married

But most surveys (which, due to the sensitivity of the subject, admittedly suffer from limited samples and other design issues) find between 15 percent and 50 percent of U.S. priests are gay, which is much greater than the 3.8 percent of people who identify as LGBTQ in the general population.

Dear Josephus,

Only God knows who is truly married and who is not.
The state does not represent anyone - they are just a gang of thugs who occupy this land by force.
Just because they claim that someone is "married" does not make them actually married - and vice versa.
Certainly you don't need to call a relationship "marriage" if you don't believe that it is - I really cannot see how they can force anyone to recognise their nonsense.

Anyway, the concept of "legally married" is already nearly empty and has no practical implications: let's empty out whatever content is still left and erase that idiotic concept from legislation and from memory.

Josephus,

Was that the best that you could find?

The ABC recently interviewed an Ex priest who entered Catholic celibacy to cover for his homosexual preference. He has since com out and has a relationship with another man. He felt he could hide his desires in the Priesthood.
