American law should be concerned with what is objectively just and moral not with what religious adherents want incorporated.
How are people supposed to agree on whether or not same-sex marriage is objectively just and moral, or not?
I have given a very clear example of how Reform Judaism believes that same-sex marriage is objectively just and moral. The Catholic Church disagrees. How does our society
know which one is right?
It doesn’t, because there is no easy way to resolve that. Catholics, like you, will say their view is objectively correct, but Jews, like a rabbi friend of mine, will say that their view is objectively correct.
The only realistic way for the law to handle this, is to simply do what it did: states can’t ban same-sex marriage, but no one is forced to participate in one (courts have ruled that merely signing a marriage certificate is not participation - edge cases like this will continue to be litigated).
On the other hand, if same-sex marriage were outlawed, people with no connection to the Church at all (like Reform and Conservative Jews) would be prohibited from marrying due to laws favoring another religions moral code over their own.
Its easy to say morality should be objective and universal. It’s near impossible to determine what that objective and universal moral code should be. Look at this very website, there are very loud posters who dissent from the Church’s clear and unequivocal stance that the death penalty is inadmissible. Even Catholics don’t agree on what is objectively moral with regard to the death penalty. What is a law maker to do in that case?
