I understand why you were confused.
I believe in an exegetical reading of the Bible.
The interpretations of scripture that you have posted leads me to believe that you do not.
Actually, I believe yours is the more demonstrably hermeneutic reading of Scripture.
For example, I see no reason to exclude the possibility of riding a taxi to the dock when Aunt Tillie writes "I took a slow boat to China." But apparently you do, though that level of punctiliousness is practiced in almost no other area beside, dare I say, legalism.
One has to seriously wonder if that hermeneutic was actually "designed" to oppose Catholic teaching as such nit-picking is otherwise fairly rare in protestant interpretation. To my knowledge, no other sect beside the Church of Christ eschews instumental music because it is not mentioned in the New Testament. One would think all protestant sects would follow suite if they consistantly applied the hermeneutic they use in anti-Catholic polemics.
