It is not to convince you, but to impeach the position that your view is "stare decisis". It shows that there is not even unanimity between the garden variety Protestant and the Fathers of the Reformation on the most basic of issues of theology and dogma. In the absence of any authority, as Luther feared, every milkmaid and farmhand thinks they interpret scripture correctly.
It all points to a corruption of the concept of Sola Fide in which belief alone has morphed into what every I believe is enough...Sola Puto.
I don’t think I have ever claimed anything akin to stare decisis for my position on this matter. See my previous response about errant councils. It is the RC potion that is more akin to stare decisis, seeking, as it were, binding confirmation in the form of past precedent.
Original intent is sometimes a tricky thing to discern, but relying on bad past decisions is not the way to get there. I admit that sometimes there was just a touch too much Rome left in Luther and other reformers.
