Here at CC we can hash out doctrines at our leisure, 24/7, yet are probably more divided in doctrine than any town of churches I know of. When we see unity kick in here, maybe we can expect it among the many church denominations. Then. how long might our unity of doctrine last? 4 hours? Wishful thinking!
In the real world of face to face worshipers, hand to hand in physical assembly, here's some simple facts.
We have far more Christian members of churches than could be put in one sanctuary, they say. Due to a very low availability of funds, hardly anyone tithing, no pastor able to budget anything significant, the new arena won't let any church rent it for a service unless paid up front. There's a fund set up for a meeting of all interested Christians near Christmas to come together to pray and discuss how we ought to minister to this city's dire spiritual and social needs. So for now the acceptable solution is for each church to remain as they are, attempting to fill their own pews on a regular basis.
It's obvious that had there been a church facility built to accommodate all of us as one body, that big "super church" building would be in default today.
Another church denomination entity has arisen here. An AOG church was split over the music and dress code of singers whose entertainment specials were beginning to resemble MTV productions. The music and voice talent is amazing, the young folks jumping and dancing for hours sometimes, the lyrics unknown to most elders. That's a bit tiring for us elders. Most can't stand so long, and certainly can't be doing calisthenics that long. It's all designed to appeal to young people, with the women singers wearing see through lace-like clothing, lots of leg showing, bare backs, kicking high.
The older half of the church, and some of the young adults, was told that's the way it has to be, so they finally left. They are no longer AOG, but something _Assembly_. I'm still trying to figure it out, will probably have to call some of them, though it isn't any of my business. Those that left favor straight Bible preaching and teaching and songs based on scriptures, modest attire, and an air of proper fear of God. Most are rejecting the modern Grace Only teaching there. Sinners love hearing they are saved no matter what they do while believing in Jesus. Again, this was once a typical AOG.
Both are full of some of the "salt of the earth" Christians I know well. Maybe both are doing the right thing for different people groups. But now the one is two mostly over worship style.
The Internet will teach you the Church is divided over doctrine. What I've found is mostly differences in how a worship service should be conducted. The doctrinal statements of all so far are identical, maybe a copy/paste thing. Many members couldn't come here explaining their take on doctrine, but they tend to know somehow false teaching is false, just doesn't sound right.
In the case above the issue was not "the Church" dividing, but one church running off worshipers who can't go along with dramatic changes and dubious messages. Their base denomination headquarters didn't help them. Now the erring church is in trouble financially, the tithers gone, filled with mostly unemployed college graduates and younger, plus some that are older but clueless.
That's just one reason about 7,000 churches close up permanently every year in America. Most of those former members have no idea how to regroup, so remain without assembly, most local churches too small to take in one more family.
