Shouldn't be too hard as the outlook is changing year after year. Just as the Bible projected views of interracial marriage being a sin, this too will eventually pass.
Not really. At least as it relates to mainstream Christianity, and specifically Christian pastors. There have been some denominations that have endorsed homosexual marriage, but nothing has really changed when it comes to Christian pastors talking about the nature of homosexuality. This is one area that is pretty clear when it comes to Christianity.
I would agree that society's outlook has changed, dramatically, over the past 20 years or so.
The Bible says interracial marriage is a sin? Where?
