And you are absolutely right to do so. I wouldn't presume to hang the entire doctrine on this verse alone. But I hope it at least helps show that the early Church calling Mary the "All-Holy One" had a basis in Scripture.

Not really. I consider it serious warpage of the meaning much as the homosexuals warp the scripture to support their lifestyle. From saying that Soddom’s sin was lack of hopitality to saying that the bible teaches that it is a sin for a man to lie with another man only if he is heterosexual. And yeah, their arguments have a basis in scripture, depending on which interpretation of the original text one uses.
