If that's true, then their sourcing and numerous other practices violate much of their own scripture.
In-N-Out (a burger chain) is another company that prints Bible references on packaging. Their labor practices seem to live up to the values they proclaim, so I'm fine eating there when I do eat fast food. (ETA I don't love their inherent support of feed lots.)
I'm fine with religion, but if someone starts trying to evangelize me, I probably know enough of their scripture to call them on ways they should practice before preaching. Not to single any one group out, but am particularly non-inspired by evangelical Christians who actively maintain ignorance of labor and environmental practices supported by their purchases, because they "need variety."
