My guess is that those doing the 'justification' don't believe in the bible, or rather believe that it was written by man and thus contains errors. I am not kidding about that, you be amazed at how many mainstream denomination leaders will state that. Or perhaps they are of the branch that believes the bible to be a loose-leaf document....
The Bible is just a historic text to them now, no more inspired than the latest NY Times editorial. They worship at the altar of political correctness.
Revisionists who make political correctness (or their own deviant desires,or those of their friends) trump everything else always find ways to explain things away, or to "prove" that they aren't "relevant". I've heard all their arguments, which are based on specious Biblical "exegesis", fifty-year-old genetics, and the "life stories" of gays and lesbians. It's all a bunch of garbage.
I am not a rationalist, but an Evangelical Catholic/Evangelical Orthodox Christian believer. What is happening in the Episcopal Church, and in my own Evangelical Lutheran Church in America, is not only a case of "bad logic", but is UTTERLY HEARTRENDING. If the ECUSA has left the one holy catholic and apostolic church, do I take communion in an Episcopal church? (ECUSA and ELCA are in full communion.) What if an Episcopal priest presides at communion in my own congregation? What if I know that the Episcopal priest is orthodox? What happens when the ELCA "goes gay"--as it almost certainly will--in 2005? Will I be able to take communion anywhere? It just gets worse and worse.
As an honorary Serb, I already attend an Orthodox church about once a month. So I do have options.
