Welcome to Gaia! ::

No... however it is NECESSARY for spiritual growth that you fellowship with other believers. This includes worship, bible study. You do not want to remain stagnant in your spirituality.

i know exactly where you're coming from. i had the same problem with a church i had attended my whole life and i had to leave. for a while i was okay, but i started feeling separated from God because i didn't have fellowship to strengthen my faith. a lot of churches are having this problem, but i've found that small groups and home church groups tend not to have this problem. try looking for one of those.

This verse isn't saying that you have to go to a church building, but you do have to go to "church."
And what is the church? It is the body of Christ. It is the members, not the building itself. The building itself means very little. I would seriously consider the above passage when deciding not to get together with believers, even if they do have sins. You and I have too many sins of our own to choose which sinners we don't want to be around.

Not every church is perfect. None that I've ever been to is, and I've gotten around in my time. Consider this. Perhaps God has a purpose for you in this imperfect church. God had a reason for sending His perfect Son into this disgraceful world, and it could be that you have a reason for being in that church.

you just have not found the right church yet. keep looking and look to God for where you should be. if your interested my church also does a online stream of our paster on sunday at 7am 9am and 11am. go to churchforallnations.com my paster is a real believer and loves God like no other.
