First glance: Mark thinks that scripture should interpret scripture. Homer disagrees--he thinks that scripture should interpret scripture.Homer wrote:Mark,
You wrote:I never said or implied anything of the kind. "Analogy of faith" leads to eisegesis. The best commentary on a passage of scripture is other scripture.I see..So the concept that scripture interprets scripture is just some kind of high ideal, but certainly not attainable?

Second glance: When Mark is talking about "analogy of faith", he means "Scripture interprets Scripture". He's probably including the concept that we use clearer passages to interpret less clear passages. Homer is disagreeing because he thinks that in practice, "analogy of faith" means using already-present theological commitments to overthrow the meaning of passages that contradict those commitments.
If I got that right, then the two of you should either recognize your agreement on the principle of "Scripture interprets Scripture" and leave it at that, or focus your argument to what you're actually disagreeing about.
