I’ve heard a counter-argument for Sola Scriptura explaining that the Bible never says “scripture alone is all we need” for salvation. The argument seems to follow the logic of “Everything in the Bible is true, but that doesn’t mean everything else is false. While scripture is necessary, God never explicitly says that’s all we need.” While there is certainly more complexity to the full argument, it made me think of a counter-example regarding the eucherist: what looks like a wafer of bread is actually the body of Christ, because Jesus explained in John 6: 50-51 “This is the bread which comes down out of heaven, that anyone may eat of it and not die. I am the living bread which came down out of heaven. If anyone eats of this bread, he will live forever. Yes, the bread which I will give for the life of the world is my flesh.” Couldn’t a similar argument against Sola Scriptura be used to support consubstantiation? Just because what looks like a wafer of bread is actually Jesus’s flesh doesn’t mean it’s not also in fact bread?
