Bingo. This is precisely why the language was ill-conceived, and Bachmann signing the pledge (as written) was even more ill-conceived.
With one caveat. Biblically literate people would understand the concept of “being slaves to sin.” God gives insight into what that would mean. Otherwise it’s so much babble.
“Pledges” like these are stupid. They are meaningless and will only serve to make those that sign look like they support something they don’t. They aren’t laws or regulations. What is the point?
