True, but Acts 2:46 does not exclude weekly meetings either. We should absolutely gather as believers outside of Church services to grow closer as a Body, as well as to talk about God and His Word. This is what Bible studies, church socials, and even just casual gatherings among Christian friends are for. However, none of that means we shouldn't have organized meetings once a week.
The NT model is a great model for how the church ought to behave, but that doesn't mean every church has to be small or meet in homes. The Early Church met in the way it did in part because it was so young and small, small enough to be viewed as a strange offshoot of Judaism that was allowed all the legal exceptions given to mainstream Judaism (at least for a little while).
Furthermore, the Church was forced to meet in secret until the reign of Constantine. It was dangerous to meet in specifically designated buildings, so people met in houses, catacombs, etc. It's telling that pretty soon after Christianity was legalized in the Roman Empire, congregations began building churches because the risk of being found out was no longer present.
Arguably, the problem with most megachurches is not the size, but that they tend to water-down or otherwise compromise on doctrine and the Gospel. There are active megachurches that preach a false gospel. The problem is not what they are doing but why they are doing it.
I'd also like to point out that just because someone is not actively serving in their own congregation does not mean they are not actively serving in other ways, such as through Christian organizations not based in a particular church, but I digress.
I think it not to do with the day of the week or the time of day or the frequency of meeting..
Its more about the mindset and tradition and motive.
Take a wide overview.. (Comnent here aimed at the whole thread) Here is ONE scenario form.but its roots trace back only to manmade origins.
A group of believers get together on regular basis.. Often instigated by an individual.
Who has been trained at this or that bible school seminary or other.
Others join and the numbers increase a bit..
There is actually no need for the group to all meet in one place on one day.. There are a myriad of options.
But.. That person has been trained that " This is the way you do it" so here at the beginnings of it we see tradition taking lordship over Jesus himself.
Then they get a " vision" ...they call it such.
They will procure a building to meet in.
There is actually no new testiment command or instruction to do so.. (As is the case with most of mans churchy traditions, they dont have a scriptural origin )
Then comes the enthusiastic call and coercions for $$$ monies.
Never mind the fatherless and the widow...we Must have our building ,we Will have our building..
Then off to the world cap in hand for the loan..
And thus the borrower has become slave to the lender..
It all rides along on a wave of carnal enthusiasm.
Then the funds drop off and pressures come on to meet financial obligations of the money master..
Then on sunday at 10.05am ,you sing and praise god your under grace not law...your told.. And three songs later at 10:20am.your given a peptalk reminding you of your obligation to obey the LAW of the tithe from a misrepresented verse in Malachi..
And now everthing has become a contradiction ..
Now of course in this scenario i used probably a picture of all evangelical charismatic type systems...
The older established man made systems already have thier huge chapels of stone traditions and how They obtained those is often a far darker story on the backs of the poor or lied to , to get them to buy recited written prayers to get thier passed on relatives out of hell fire... A tradition also with zero scriptural origin . prayers for $profit..
The protestants then did coercions.. The evangelicals then did it.. The penticostals and charismatics did it...
Often in this thread people have said you cant make such a broad statement saying the theology of church leadership is corrupt..
Yet we see this one Form alone of corrupt pattern in how many denominations.. ? All of them .
And if not tithe... Its what is done with freewill offering..
How much of it is poured into the upkeep of old dead shells called buildings ... And the poor are sneered at for not attending the buildings then if they do attend are they aided? (Theres always the exception) but they also are coerced by suggestion and implication ..to hand over monies..
This all is just one single area ...
Yet it is repeated and perpetuated over and over through generations...
And why?
Because the man made church systems makes for itself diciples of the man made church system who then do the same.
But we were never called to be diciples of the church .
But Diciples of Jesus...
Think it through ....step back and take a wider look
