It's a great letter.
Very fair, very faithful, and it does not ask for money or donations. The marriage amendment letter was reported to be a letter asking for donations to support efforts promoting the amendment. I read it several times to see if the bishops asked for money as the opponents have claimed. They only asked for prayers:
We know many have already supported efforts to pass the amendment. We now ask for your prayers for our state, that we may reclaim a culture of marriage and family life. Marriage needs to be strengthened, not redefined. Please join us in this historic opportunity to affirm God's plan for marriage in Minnesota. - Bishops letter.Nothing wrong with that - so read what the bishops and the Church really say and not someones interpretation of what is said.
"Statutes can be struck down or changed at any time, but if the amendment passes, activists who seek to redefine marriage will first have to get the permission of voters to do so."
In the body of the letter the bishops tell of a lawsuit currently pending in Hennepin County as well as legislators who have introduced legislation to redefine marriage or eliminate it altogether - failing that, they promise to reintroduce the legislation next year. And the next year - until they get their way. The marriage amendment would halt that - although I'm sure lawsuits to repeal would be the next fight.
Nevertheless, the bishops make clear that the marriage amendment will not take away any one's existing rights or legal protections. People will still be allowed to visit and care for their loved one in the hospital, nursing home, and so on. People will still be able to will property. They will continue to have equal access to employment, housing and the basic necessities of life. Though they do not mention it, companies which provide same sex benefits will continue to do so. What the amendment does is to promote and protect marriage and families as the 'unique relationship that is like no other.'
