Where I think the ELCA and LCMS are similar on this is in the actual situation on the ground. In the ELCA, some pastors celebrate and affirm homosexual relationships as God-pleasing and some condemn such relationships as sinful. That is an untenable situation, and the CWA accurately identified it but chose to offer an incoherent principle of bound conscience to account for it. In other words, the statement is incoherent because it accurately describes an incoherent state of affairs. In the LCMS, some pastors celebrate and go out of their way to have women as communion assistants while others decry this as false practice and un-Confessional. That is also an untenable situation. The LCMS, however, instead of offering an incoherent description of an incoherent situation, chooses to offer a perfectly coherent but inaccurate description of an incoherent situation. It makes perfect sense theologically to agree that women may be communion assistants but also to agree to recommend against the practice, which is what our statement says. It is adiaphora, but there are good reasons to prefer one choice to the other. But that isn't a true assessment of the situation. In fact, many pastors do not at all agree that women may be communions assistants and many others do not agree at all that we should recommend against the practice.
This is why I take Andy's post as an example. He makes perfect sense, but he is not saying what the synod says. The synod does not say, "Some pastors say we can't, so we don't lest we offend our weaker brother." The synod, at least in theory, proposes that every pastor at the youth gathering might agree that it is adiaphora whether women assist with communion and that every pastor would also agree that it would be a bad idea to do so. That isn't at all what Andy is saying, and I think Andy is speaking the real truth of the matter. So it is true that it is an apples to oranges comparison in the sense that the ELCA has a philosophically incoherent position that accurately reflects an untenable situation while the LCMS has a principled, philosophically sound position that bears little semblance to that actual state of affairs. But where the comparison holds true is precisely in the actual state of affairs, in which different preachers in the same church promote and denounce the same thing.
