I'm asking for 20 differences. That's all. Here's the original claim.
Note: He says, None of them can agree on much of anything about their mythology. That's a huge over-reach.
So, I asked for a list of 20 differences, things they disagree on. 20 things should be an easy list. Something like:
- Unitarian / Trinitarian
- Faith by works / Faith by grace
- Eucharist / no-eucharist
- Predestination / no-predestination
- Solo-scriputa
- Biblical literalism
- Mosaic law / New covenant
- etc...
That's basically all I can come up with.
If we look at Pew, they break it out into less than 20 groups, but non-denominational & other is a pretty large group under protestants.
Hartford Religious research did an interesting study, they broke it out into 99ish groups. Half of those were non-denom congregations. FACT did a study of the non-denoms, and broke them out into 5 major groups. So one the one hand there's 99, but if those no-denoms are taken out and replaced by their theological differences, the actual number is closer to 65.
Even if that number is off by a factor of 10, that is only 1000 denominiations. And that's much much different than over 30,000.
But big picture: do all of these different faith groups really, actually, disagree that much? I vote no.
In that same study by Hartford, they indicate that a large number ( 50% of the responders ) switch denominations. This shows that denominations don't have major theological differences that prohibit switching to a new group. Also, non-denomination churches are growing on a massive scale. The entire denominational divide is shrinking, and a large number of Christians seem to appreciate that.
So that's the trend. And that trend is: there aren't that many theological diffrerences.
As I'm researching all of this, it seems that the number 1 deciding factor for people when determining a congregation for their home is worship style. It has nothing to do theology differences. Or as
@Ancient Soul put it, "they can't agree on anything about their mythology." That has nothing to do with it. They like the worship services, then they learn about the theology after. The pastors quoted in the Hartford study say their classes to teach about the congregational theology are completely packed with new members. This means, the members are joining without really needing to know about the differences. The differences aren't that large or aren't that important.
And, I'll just post this little quote from
@Ancient Soul. This in my mind justifies pushing him to back up his claim with facts.
