Annalex. All I can say is study Scripture. What Calvin says, what Luther says, what Augustine says, what any man/woman/child says is nothing if it contradicts Scripture. All Scripture is given by God and is profitable for Doctrine, for reproof, for instruction in righteousness.
Scripture is where you will find the truth and the Holy Spirit will lead the way.
Guess we better let the thread try to get back to Mary somehow. Though the other discussions do become relevant when a particular group claims authority to be angry about her portrayal. Such authority deserves to be examined, which I think we've done.
Have a good day.
Good. Let me state in conclusion that I do not think that the error of Luther is adopted as a true theology out of any malicious intent by you or anyone I converse with. It is, nevertheless, a grave error. Mariophobia is another.
