With all due respect, you should investigate the Roman Catholic Church, which is simultaneously the most hard-headedly realistic AND the most mystical of the Christian Churches. I did, converted, and don't regret it for a second.
I have, and it doesn't work for me. But for the hundreds of millions who are happy with it, more power to them.
I don't view the various denominations of Christianity as competing teams where only one is the true Church. Finding one that is personally helpful to you in your search for truth is the important thing. That might be Catholic or it might be evangelical.
The various flavors of Christianity differ on the details.
