Hmmmm. Well, brother, you're condemning a lot of people by saying most are there for selfish reasons. You my friend do not know the hearts of people, and apparently you hold them in some disdain. Keep in mind I'm a member of a church, so are many on here that you're condemning, and you're talking to us here.
You've determined that you are not sinning by being out of church, but I would have to say that you are indeed "missing the mark."
I want to put it out there; no perfect NT churches existed, they weren't all perfectly biblical, just look at all the issues within them, yet this was not an excuse to leave them and label the persons there as selfish or any other such thing so as to have reason to depart.
There are in any given church those who have "not bowed their knee to Baal." They exist in churches you've visited, and are among the many you've condemned in your disappointment. I know it is easy to do when it seems so discouraging.
You probably would have left these early NT churches as well because the same issues existed, so the statement by many "I want our church to be like the early church" is not well thought out.
Now, there has to be much more detail to the problems you ran into with the two pastors. Did they wish you to stand and condemn Billy Graham, publicly, and you refused? What I mean is, how did this come about? And the elephant in the room; why would you not condemn him? He was ecumenical, preached some mysticism (people are saved outside of Christ) since you deem others as going for selfish reasons as reason not to attend? I think the issues with Graham were far more serious than determining people go for selfish reasons.
Why should people go to church, for what reason?
So a pastor didn't visit you? We were in a church for a long while, barely did the pastor or his wife ever speak to us, but to all others yes. They refused to visit us or others who visited there. Flat out refused, said so from the pulpit in attempt to drive us out. This church was all of 20 people, so it wasn't that it was too big, there were internal issues, power struggles, truncated gospel, no out reach, and a Diotrophes attitude.
But we stayed there regardless of his asinine attitude until God moved us along. We don't let people drive us out like that until we know it is from God.
Yes, the preacher got it wrong on a detail concerning the ram/lamb, yet, that is no reason to walk out of a church. Yes, he was wrong brother but that is one bizarre excuse to leave.
Bottom line is there is no reason for you to be out of church, you're out of church because you want to be and apparently any excuse will work for you. None of the reasons you've given are biblically valid reasons to be out of church.
