As a logical matter, how can Luther’s doctrine of “the Bible ALONE” be the sole rule of faith, when it isn’t in the Bible?
As a logical matter how can much of Catholic doctrine stand when it isn't in the Bible?
Like *Sacred Tradition* being of equal standing with, God breathed, Holy Spirit inspired Scripture?
Like the alleged sinlessness of Mary and her alleged perpetual virginity?
What about purgatory?
What about praying to Mary and the saints?
I’ve never argued for Luther’s doctrine of the Bible alone so are you asking as a rhetorical question?
But if you wish to argue logic.....I would begin with a simple question: If one is to rely on tradition, where did these traditions come from?
