Or I may not. Did you notice my 'tag line'?
I think it's a false opposition. I often err, but I try to choose my words carefully. So I spoke of the way in Christ and to Christ. It is not that I save myself by my works. That's patently ridiculous, at least, knowing me, to me. But Jesus prepares good works for me to walk in (Paul said that) and then "walks me" through them. (Paul implied that In Philippians, IMHO.) Anybody who doesn't think the whole thing is a gift isn't paying attention.
You're open to a "non-literal" interpretation of "this is my body", then. Great!
We say it is "really" His body and blood. We do not say it is "literally" His body and blood. (D00d, I'm a Dominican. We LIVE for distinctions.) "Literally" seems to convey something but leaves all the big questions unanswered.
