It makes not a lick of difference who taught or thought what...We have the words of God which tell us and you that they ALL are wrong...
And who compiled those words and when? The Bible, as we know it, was formed as volume around 400. Some of the Marian doctrines pre-date the canon, so ...?
The disciples who learned at the feet of the Apostles were teaching the Gospel before it was even written. Those teachings were recorded in letters, such as those between St. Irenaeus and St. Polycarp, both 1st century bishops and martyrs.
So, which do you believe, or do you believe both, neither?
