Rather than get into extended back-and-forths about specifics, allow me to start a new thread to propose what I think a few principles should be in extraordinary times:
1) Though innovation is unavoidable, the less innovating the better.
None of our churches is functioning as normal. All of us have introduced novel practices previously unknown within our lifetimes - we should be honest about that.
But the less novelty the better.
This isn't just a conservative thing. There are many reasons for this. Firstly, a hurricane is a bad time to start testing new designs for lifeboats. If it wasn't a good idea a month ago, can you be sure it's a good idea now?
Connected to that, decisions made under severe stress and time pressure are less likely to be carefully-thought-through and thoughtfully applied.
Lastly, in times of crisis, the greatest human needs are documented to be predictability and agency. People need to know what's coming and to feel they have some control over their own circumstances. Whole-scale innovations actually lessen the first, though watching Pr. Tricker's video, I saw loads of evidence that he and his people are leaning hard into the second.
2) Even within innovation, the greater the connection to regular practice, the better.
I know that some churches value "creative thinking" as being "part of their DNA". That's a discussion for another day. But even those churches probably aren't introducing some new worship format or disbanding their praise bands or their choirs at this time. Staying the course as much as possible is an obvious principle that most churches are at least partly following.
On the one hand, the mega-churches are really stuck... Since my regular Sunday attendance is 100, and many have self-quarantined or are avoiding all outside-the-home contact, I can still meet in church and fulfill all of both the state's and the CDC's requirements (last Sunday's attendance: 33, all sanitized and at least 6 ft apart). But a church with weekend attendance of 2,000 cannot. On the other hand, a church with attendance of 2,000 usually has a pastoral staff of 6, 8, or even 10 rostered workers. My church has 1. I know it depends on each state and municipality's regs, but a church with a pastoral staff of 10 and a large facility has a lot of options that don't necessarily have to involve anything brand-new.
And since most pastors are not pastoring mega-churches, what options are closest to regular practice? These options are probably to be preferred.
These are two examples of principles I think churches must be discussing right now... Other ideas?
