I do think it is important that we do not take up the disagreement in the time of crisis, in the heat of the battle, so to speak, as long as everyone understands that these things must be taken up with all seriousness when things settle down. They can't just be acknowledged in some token way and then shrugged off with, "Hey, it was an extraordinary circumstance, and the time has come to move on, why bring up divisive things when there is no reason for it right now, etc."
In the internet era, there is no "contextual" difference. People watch your services from all around the the country and world. Everything an LCMS congregation does is thereby, in real time, declared to all LCMS people, in and out of that context, to be acceptable LCMS practice. I've already gotten emails about yesterday; "Hey, I saw one congregation just did communion with everyone in their houses. Why can't we do that?" That leaves me in the position of either saying we can (which isn't true), or those people were wrong to do that (but again, this isn't the time to focus on that kind of problem with so much else that is pressing and extraordinary going on), or that we could do that but we aren't going to, just because. That puts me in a tough position, all so that people in San Antonio or this or that other place don't have to do what virtually everyone else is doing, which is making do with services of the Word and/or individual rather than corporate communion.
This dynamic is key to the LCMS. People treat it as the church. If you're doing it, you're declaring it acceptable practice in the LCMS, and you're declaring that to anyone with access to a search engine. Please bear that in mind.
In my case, I had/have a strong inclination to continue offering services to anyone who would come. But when that position feel so far into the minority, I decided it would be uncharitable, and not merely to my members who might feel obligated against their better judgment to go out despite the warnings. It would be a silent accusation against the churches in the area that closed. I'd be putting every pastor in the position of defending his decision to suspend gatherings for worship in light of the fact that St. Paul's was open. Not helpful.
So right now might not be the time to sort out all the whys and wherefores of online communion practice, although I think we've had some extremely helpful discussion of that topic in this forum. But it definitely is time to remember that context is out the window, and to make decisions bearing in mind that you're preaching/teaching/leading worship in the name of your church body for anyone and everyone. Don't do anything controversial, even if you think it could be justified. Focus on doing things that few, if any, could have any problem with.
