Babylon is not only a famous city/state but also a symbol of God's wrath in defying His commandments. St. John's Revelation is packed with information and the effects of Babylon's fall.
The writing of the New Testament, much like the Old Testament, conveys the entire Bible in many ways. Copying the text gives and preserves the Holy Spirit at work through the Holy Spirit.
When I pray at night, I always include the Holy Spirit with the Father and the Son, because efficacy has been neglected. Luther said - more or less - "This is really good stuff!" when he was tossed into the doctoral role of studying the Scriptures.
Listen up on this - the Spirit is always with the Word (invisible and invisible) and never apart from the Word. That is the simple description of the Means (method) of Faith (trust in God). That means the Word of God in all forms will affect the reader/listener/even the teacher/preacher.
More listen up - the false or sloppy user can take on the Spirit for harm and corruption - effective but in the wrong way. If anyone doubts that - study the ghastly modern hymns of today, the textbooks of seminaries (any seminary will do for disasters), and see how the horrid hymns drive people away.
A good text - the KJV - and good hymns will always improve the knowledge and spiritual wisdom of the readers. The regular, steadfast reader will find the effectiveness (efficacy) of the Word to be a great and lasting effective on one's soul.
In contrast, people can reach for spiritual cotton candy, which is only good for a few minutes - sticky, messy, and worthless.
