I've always had various bones to pick with "organized religion" or more specifically, the modern Christian [sic] church. I left denominationalism because of the growing list of issues in organized religion, only to learn nondenominationalism isn't much better. There is not one that I could feel good about recommending to new believers, for example.
Several heresies are commonly taught including tithing, Prosperity Doctrine, subtle forms of antisemitism (often including Replacement Theology or merely apathy toward God's Chosen People), Sunday Sabbath, various levels of rejection of the Tenakh, seeker friendliness, and more and worse. Most of the good churches--the best I could find--still teach most of these heresies. Even setting aside their heresies, I've yet to find a church that doesn't overtly and insistently violate God's will regularly (and I mean on big issues, not whether or not to put in stained glass or such benign matters).
In each church I've attended regularly, I've attempted to open dialog with the senior pastor and/or leaders. I've tried to engage them in discussions about areas I believe need improvement, trying to avoid any bashing of their obviously unbiblical stupidity (yes, contrary to what you may see on my blog, I can be a nice and tactful guy), and earnestly looking for common ground upon which we may build solutions. All my efforts have been flatly and universally rejected, occasionally rudely. It seems church leaders cannot be bothered with their own sins. Or perhaps they simply cannot set aside their enormous and unjustified egos to momentarily consider another point of view (e.g., a Biblical one, to be brutally frank). I'm somewhat embarrassed to say, I've given up defending the Truth against egotistical, maniacal church leaders.
I once thought the only reason I attended church still was to fulfill the command to "gather together" as believers. However, I know there are many ways to fulfill that command, and the modern church isn't the only way. (I could argue it isn't even a valid way anymore, now that they've abandoned the Word so badly.) Now I know I still attend church merely because it's traditional to do so--more of a habit than anything else. I'm almost embarrassed to admit where I attend church when asked, and yet I attend one of the better ones.
I'd like to find an alternative to the church we're attending now. I started a housechurch once, but I do not believe this is my calling. My ministry is much more one-on-one. I like the idea of a housechurch, but they also have their issues (doctrinal heresies again, leader egos again, no accountability). I'd like to find a church wherein my gifts and calling may be put to Godly use, but I just don't think it'll happen in this age. In the meantime, I must be satisfied with ministering to those few to whom the Lord leads me.


Me too
Right after I received the Lord, I became a member of a nondenominational pentecostal charismatic church for over 8 years. I learned many incorrect things from the pastor who eventually "backslid" into drugs, prostitutes, etc.
Then I (with my growing family) found another church and have been there ever since (since late 2001). But it's a "megachurch" and I'm finding faults with it and the doctrines being taught as well. Tithing is one, and it's the big one.
My husband and I have served in Children's Ministry as leaders for some time and while I am not frustrated with the cirriculum, I have found myself completely exasperated with the "machine" that is this church. The church staff just simply do not seem to be on the same page, so miscommunication abounds. And now, there is yet another major change going on - pastoral change - for Children's Ministry, and the director I used to serve under is now no longer working at the church as of this week.
I have been taking a break for this month just to see if I could come to terms with my feelings and get over it, and get enthused about serving again, and even just attending a service. But the more I ponder, the more I just want out.
I know there is no perfect "church" (organization) out there as they are full of imperfect people, but I would hope to find one that truly seeks God's face before His hand, and teaches as much truth directly from His word without twisting the meanings.
