Oddly enough, that sums up most Reformation beliefs as well.
Seems to me that using Scripture alone is exactly what the Reformationists were and are criticized and condemned for, because they didn't accept the extra-Biblical teachings of various men's opinion pieces.
Which is it? Are those of the Reformation to be criticized for following Scripture alone (sola scriptura), or for holding to doctrine not found in Scripture (tradition).
I do wish Catholics would make up their minds.
