No, that is not the end of the story.
You are not predenominational. There is no such thing. And I am in no mood for word games. You are not 1900 plus years old. You did not exist before denominations. I don't need to hear a pack of lies.
Secondly, almost all Baptists believe that the Bible is the supreme and final authority for their beliefs and practices. So what makes you any different than the rest of us, on that account? You interpret it differently, and that is your prerogative. But don't think for one moment, that we believe any different when it comes to that principle.
Thirdly, your conclusion has no basis in logic. If it did it would mean that we would all have to put "no denomination." Technically I agree. I am not a part of a denomination. I belong to an independent Baptist church, which is totally independent from all others--no denominational affiliation, no association, no convention, etc. We are completely independent. Thus I don't really care for the name denomination either. But there is a need for identification as explained in the profile. It is not hard to figure out, and I am sure you can do it.
Fourth, "You worship in a house church." Good. Who do you worship with, and what are your beliefs most in line with? Does your "house church" have a name. Are you located in a place? Do you not have some identification. No, I don't believe you have been honest.
