>>I asked yesterday and have not yet received a response, but why is it that someone who is such a devout adherent to the 16th Century invention called “sola scriptura” so frequently quoting from books other than the Bible? <<
Hmmmm, a puzzling question.
It’s always interesting to notice which questions go unanswered.
The question is based on an absolute falsehood, thus is impossible to answer.
1. John Wycliffe, died 1384, in 1428 he was convicted by the Council of Constance of heresy for teaching Sola Scripture. His bones were dug up and burned.
2. John Hus. Burned at the stake in 1414. Heresy. Sola Scriptura.
ST. AUGUSTINE OF HIPPO* (354-430)
In those things which are clearly laid down in Scripture, all those things are found which pertain to faith and morals. (De Doct. Chr. 2:9)
Whatever you hear from them [the Scriptures], let that be well received by you. Whatever is without them refuse, lest you wander in a cloud. (De Pastore, 11)
All those things which in times past our ancestors have mentioned to be done toward mankind and have delivered unto us: all those things also which we see and deliver to our posterity, so far as they pertain to the seeking and maintaining true religion, the Holy Scripture has not passed over in silence. (Ep. 42)
Whatever our Saviour would have us read of his actions and sayings he commanded his apostles and disciples, as his hands, to write. (De Consensu Evang. 1:ult.)
Sola Scriptura!
If Augustine had lived a thousand years later he would have recanted this "heresy" or died a fiery death.
Now you know the story. To claim "Sola Scriptura" was a 16th century invention is to lie.
