Simple study can cause all sorts of error. I know many homosexual Christians that have shown through a “simple study” that the Bible does NOT condemn homosexuality as a sin.
That said, the message of Christianity is both VERY simple and extremely far reaching. People add way too much irrelevant fluff - like the perpetual virginity of Mary.
So, your study reveals that the historical view that the Church has believed and taught the perpetual virginity of Mary throughout history through at least Luther and Calvin - is an error.
Care to show your work on revealing this error?

Understanding fully who Mary is is a key part of understanding the Incarnation and who Jesus is. That this is "irrelevant fluff" is ignorance of, and an insult to, orthodox theology.
