Jesus was a Jew. His father's house wasn't a Christian church but a synagogue.
Everyone has a unique relationship with the father . If some feel led to a church building for community so be it.
I don't believe God will condemn those who find nature, the outdoors, Bible study groups meeting in different houses throughout the month, worthy of condemnation because we didn't meet in a traditional church.
Even though I no longer attend and support the institutional model, models for meeting, all of which are flawed in various ways because of fallen human's involvements, plans, envisionments, et al, can be used of the Lord. The institutional model has been used mightily by the Lord, irrespective of man's having created it and exercising control over it, and man standing in its limelight with all his silly titles and positional elevation above all the rest of the people who plop their "tithe" into the passing plate.
In the house churches I have seen and do attend now, there are psalms, songs, hymns, praises, teaching...everything Major talked about, with two other items that the institutional model rarely does, which is a meal together and open sharing, apart from band-aid programs. We sometimes go out into the trees, whatever we so desire, because the gathering of believers, the primary purpose, is not for praise, and not for worship, as is the common and historic beliefs. Those are good things to do corporately, but they are not the sum total of purpose the Lord had in mind, and that is the one thing that's disallowed in the institutional model in 99.999999% of all church organizations.
Sorry. Just had to interject some thoughts. The prime purpose scripture specifically mentions of the purpose for the gathering...mutual edification. I never experienced that looking at the backs of other people's heads throughout the main gathering. Oh, I could launch into the history behind "cell groups" and such, and talk about how and why they came about as the motivation behind them, but will leave that for now.
Where I stand in it all, however, is that for those who feel they are blessed in any of the models, and you are meeting the One, true Lord there, then go for it. What I encourage the most is that you find a group who practices what scripture reveals as the prime purpose for the gathering, which is mutual edification.
