It is surprising that those who know the Church does not adhere to sola scriptura, still expect some kind of lined-out, word by word, one meaning possible only, systematic theology.
If Christ had established a sola scriptura Church, perhaps the Church would, but then there would have to be many different versions of it, to cover all the different sola scriptura interpretations we see using this doctrine.
But then, the Church would not be One, Apostolic or Catholic.
Protestants just cannot grasp the fact that our bible was not sprung full grown out the head of Zeus.
