If there is no letters of the law of Christ to obey, then there also is no letters of Christ, of His Gospel, nor His word and doctrine to obey:
The beginning of the gospel of Jesus Christ, the Son of God; As it is written in the prophets, Behold, I send my messenger before thy face, which shall prepare thy way before thee.
How do we know the gospel of Jesus Christ, as it is written in letters, if it is not written in Scripture with letters to obey?
But I will shew thee that which is noted in the scripture of truth: and there is none that holdeth with me in these things, but Michael your prince.
These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.
If not for the letters of Scripture, then how in the name of Christ does anyone ever know the truth of God's word, gospel, doctrine, law written in letters, much less to obey them?

Which is why we are seeing them so twist, mangle, or ignore so many dead letters of Scripture on paper.
