Ok, let me see, I will try to make this simple and plain.
1st. Question. What is a “institutional church”?
Ans.”Google” It. It can give a better description than I.
And I sure agree with you on this one. 100%
“You said: Every fellowship must have some kind of institution if it's to last more than a few years.”
We must all thank God, that His “Congregation “ is not like “The Institutionalise Church”
Thank God, all ye people of His!
International Standard Version
I tell you that you are Peter, and it is on this rock [Jesus] that I will build my congregation, and the powers of hell will not conquer it.
And concerning the “7 men” it makes plenty of sense. There was “No Social Services” it was great “Poverty” in that era of time!!!! Historical fact! Why do you think the people said: “ Hosanna, Hosanna here comes the King”!
the Last question you ask:
“So, is there such a thing as a non-institutional church, and where could I find it?”
Ans. YES! It is not made by the hands of a man! It is Invisiable it is “The Congregation of The Living GOD”. And HE is still building it and we HIS people are “Living Stones” and He is the “Chief Cornerstone “!
American Standard Version
ye also, as living stones, are built up a spiritual house, to be a holy priesthood, to offer up spiritual sacrifices, acceptable to God through Jesus Christ.
(1Peter 2:5).
And concerning “Discipline”
International Standard Version
For the Lord disciplines the one he loves, and he punishes every son he accepts." (Hebrews 12:6).
GOD, has His own covered! He watches over us day and night!
Shalom! My brother! For You are the Temple of the Living God! He does not dwell in brick & Mortar! Now live like it!!!!!
