Your emphasis on understanding the Bible first is laudable and it should be underscored with an understanding of appropriate theological teachings by the Church. I cannot pretend to understand the varying and often contradictory positions that I have encountered on this site, but perhaps I can make a useful comment on your approach. My background is Orthodox, and the faith-science discussion can be found on Orthodox and Catholic sources. Briefly, we have opinions that range from: (a) evolution is a theory that is part of the natural sciences, and we should have a sufficient understanding as we should of all science, to (b) evolution may be the paradigm of biology, but generally it is an ideology that its proponents push as a belief system, and have little regard to truth, science, theology or Biblical insights.
Both of these views can be discussed without the rancor and extreme views found in the US. I do not have any experience with YEC or OEC, so I cannot make a useful comment, but I am convinced that BioLogos has made a fundamental mistake in seeking to use evolution as a basis for theological understanding of the Christian faith - claiming a big tent is a distraction. Until ToE is restricted to one scientific discipline, and the faith-science dialogue is shown to involve much more than speculation based on ToE, BioLogos will be part of the waring culture that has bedevilled the US Christians.
