There has been a fair amount of discussion lately in the Mormon blogosphere about Peter and Mary Danzig. The gist of the story is that they were kicked out of the temple square orchestra and ultimately left the church because of their support for gay marriage. Northern Lights has a comprehensive list of links where this issue is being discussed, including a press release by the LDS church. So, I thought I would weigh in and offer up my $0.02 on the subject.
To be brutally honest, I'm leaning more towards the church on this issue. Now, defending the church might seem odd coming from a person who, himself, recently declared his support for gay marriage. But, the way I see it, this really isn't about gay marriage - it's about publicly denouncing church leadership.
There is a big difference between having a personal opinion which is at odds with the church, and publicly denouncing the church because they don't agree with you. To denounce the leaders of an organization and to encourage other members of that organization to do likewise is, by definition, apostasy.
As members of the temple square orchestra, the Danzig's were ambassadors for the church, which is also a factor. When you are representing an organization then there is a certain standard of behavior which is expected. If I were meeting with a customer as a representative of my employer and I denounced my employer in that meeting then they would have every right to terminate my employment.
If Peter Danzig had written to the newspaper as a private citizen expressing his support for gay marriage without pulling the church into it then I doubt very much this would have escalated as it did. This is evidenced by comments in the various articles about other people who had written letters to the newspaper expressing their support for gay marriage without any action being taken against them. So, while I'm sympathetic with his views towards gay marriage, I am not sympathetic with his approach in voicing those views.
Just my $0.02 on the subject.
