Which is not in Scripture.
Reading skill is not irrelevant to Biblical hermeneutic.
By Church, you mean Lutherans. Where do Lutherans get the idea that Scripture is the sole final norm? The terminology is not in Scripture. And Scripture says:
Matthew 18:117 And if he shall neglect to hear them, tell it unto the church: but if he neglect to hear the church, let him be unto thee as an heathen man and a publican.
Hebrews 13:17 Obey them that have the rule over you, and submit yourselves: for they watch for your souls, as they that must give account, that they may do it with joy, and not with grief: for that is unprofitable for you.
So, the sole final norm says that the Church is the final norm. The final arbiter. The Church isn’t even required to check Scripture:
2 Timothy 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
Profitable does not mean necessary.
