you can call it "Icons" or "we don't worship it" but it is still graven image and idolatry forbidden by the word of God Bible, why would anyone believe anything outside of the Bible which is the word of God, that is idolatry!
The teaching of Jesus, when first spoken, was not in the Bible. Neither were the sermons or letters of the Apostles. Neither was the Book of Revelation.
Most things are not mentioned in the Bible. Penicillin, Ibuprofen, Mogadon, Ritalin, Xanax, daisies, anthracite, nature reserves, books on paediatric medicine, speeding fines, Keynesian economics, international law, the Geneva Conventions, pure mathematics, Old High German, the futhark, chocolate ice cream, the Encyclopaedia Britannica, Hadramaut, peregrine falcons, lion-taming, depth charges, Oxford University, haggises, Scotch pies, tiramisu, linguine, fettucine, the Mason-Dixon Line, palanquins, hookahs, isosceles triangles, the works of Aristotle, Neo-Platonism, the Plimsoll Line, Samarkand, the Jaxartes River, polypropylene, electricity, central heating, Bath buns, Eccles cakes, pasties, linoleum, mosaics, showers, rugby football, lacrosse, tennis, rounders, soccer, sky-diving, roller skates, ice skating, hamsters, computers, iPads, birthday cakes, shopping lists, domestic cats, and very many other things, are absent from the Bible.
The list of 27 books that all Evangelicals accept as Holy Scripture, is not in itself given in Scripture. Jesus never said anything about "letters of Paul", not even to say they would be added to (what Christians call) the Old Testament. All indications from the Gospels are that He was entirely satisfied with the books of the OT. There is not a hint of the addition of any additional "New Testament" books; the books of the NT could be used as purely human works, neither God-breathed nor in any way on a par with the books of the OT. That could in principle have occurred - in practice, the churches & the Church chose differently, with no Biblical warrant for doing so. Like Jesus, and the Apostles, they greatly respected Scripture, & quoted, echoed, and drew upon it for ideas and imagery; but, like Jesus & the Apostles, they were not confined by it.
The only "new testament" Jesus ever spoke of, was this one: "For this is my blood of the new testament, which is shed for many for the remission of sins" -
Matthew 26:28 This is My blood of the covenant, which is poured out for many for the forgiveness of sins.
None of these objections tell against Sola Scriptura, other than that Sola Scriptura is not itself named in Scripture either. They all tell against Nuda Scriptura - which is not the doctrine of the Protestant Confessions.
