I shouldn't be surprised by the many, varied responses here that I've just read. Some are good but many are meaningless fluff that would apply to any false religion or secular organization. I expect any church to be loving, giving, and serving others in various ways, but that doesn't differentiate a biblical Christian church from an unbiblical one. I expect most of the misguided, liberal churches today would have many of the desired qualities that responses above advocate, but that doesn't make them biblical.
I travel full time and attend new, different churches regularly. That entails me going on-line, visiting a church's website, and determining whether it's a church I want to attend for the next 2 months or not. In my case, being a Bible believing evangelical Christian, I want a church that actually respects the faith's foundational scriptures - in other words, respects the Bible's authority.
Most churches tend to have some sort of "about" or "statement of beliefs" posted, but many leave out anything controversial or specific that might differentiate between being liberal or conservative in their beliefs. They don't want to define anything that could be considered offensive or unwelcoming to anyone. I try to avoid these churches because it usually means they're liberal.
What determines a biblical church for me is one that truly follows the Bible in its core beliefs. This automatically rules out many of the denominations and even separates the supposed evangelical protestant denominations. I find most get the Gospel message right, but it's a small minority of Christians and churches anymore that actually believe the Bible as God's authoritative, infallible Word - the foundational basis of their faith. To me, that means:
The church accepts the clearly written, literal Genesis 6-day/24 hr creation and flood accounts (vs evolution); Moses' authorship of the Pentateuch; the Israelite nation, exodus, and Red Sea crossing; other OT miracles; no women pastors leading the congregation; and a stated position against the abortion, LGBT, and gender blending culture. I find the ones that do that have no problem fulfilling the other appropriate church expectations.
In short, I think a Biblical church (and Christian) should actually believe the Bible, but polls show that only a small minority do anymore. The church body has succumbed to much of the world view's pressures, political correctness, and relative moral values by allegorizing or completely disregarding the parts of the Bible that they don't like. And sadly, even the seminaries are teaching this theology - starting with Genesis.
