I must have read that passage at least 100 times since becoming a Christian, and such an interpretation never occurred to me. Must be coz I'm a dullard. However, I'm not too concerned that I missed anything of any real consequence, coz I find myself in excellent company: it never occurred to Paul either (2 Cor. 11:3 and 1 Tim. 2:13).
I guess the trappist treatment might have something to do with this warning from the main man himself:
To the pure, all things are pure, but to the defiled and unbelieving, nothing is pure; but both their minds and their consciences are defiled.They profess to know God, but they deny him by their works. They are detestable, disobedient, unfit for any good work.
Titus 1:15-16
Hmm............draw your own conclusions, pistol-packin' grandma.
