Psalm 133 King James Version (KJV) !

[Major Nikon]

10. The Comma Johanneum is a big reason many Christians cling to the KJV

...whether they realize it or not. Many evangelical denominations refuse to adopt other translations because it is either omitted entirely or a footnote is added questioning the validity of it, or it is added by footnote with the disclaimer that it doesn’t appear in Greek manuscripts before the 14th century.

Without the Comma Johanneum, there is no reference to the holy trinity in the synoptic gospels, which is a huge problem for evangelicals. It means the entire concept of the trinity is merely doctrinal rather than biblical and invites debate on not just the concept of the trinity, but the divinity of Christ.
