This is an old thread but felt to add to it. I was out of any organized attempt at religion by the Lord's hand for probably 20+ years by this time. I was never allowed by Him to go thru the formalities of joining and pledging allegiance to any sect or it's doctrines, but early in my walk I did attend primarily for corporate worship.
I didn't go to learn what they believed, I was busy spending hours in the Word myself a day, seeing what HE wanted me to believe. If they said something that lined up with what I was seeing, that was great, and when it didn't, I ignored it or put it on a shelf for later to dissect and discern if it was "digestable". Discerning of spirits is the mirror image of our sense of smell in the natural, and as in the natural it doesn't take long to figure out if something stinks and begins to breed worms, don't eat it!
He recently let me attend, sporadically, a Messianic Jewish church, no doubt in part, because they are the closest in form to what I have had formed IN ME. And it has blessed me. I won't however, ever be a member of any church, EXCEPT the church I was birthed into, the church of the firstborn, CHRIST.
IMO this is the ONLY CONGREGATION/BODY He is interested in forming, all of the others despite their best intentions, have built their own kingdoms and I refuse to belong to an external one, when He is busy building the internal one, and the ONLY ONE we are told to fellowship with as we see the time approaching. I fellowship with HIM, wherever I find Him. And He is sometimes found in the darnest places.
