But while this may sound very much like Protestant doctrine, we do differ in this particular: we do believe good works are necessary. Protestants have called us non-Christian for this, but we believe that we accept Christ's grace through faith on our part, and that faith and good works are tied together.

I consider myself a nondenominational Christian, and what I'd have to say is that I believe we are saved by faith alone. Once saved, good works follow because someone who is saved has the spirit, if that makes sense. Look at examples from the Bible. When Paul converted to Christ he had no good works under his belt; all of that came after he was saved from a desire to serve the Lord. Is this kind of what you meant by faith and good works being tied together?
