One simple reason you should not read the NIV, ESV, NASB, and other modern English versions

Doubt is an adversary of any Christian.

However, the NIV, ESV, NASB, CSB, and most modern English versions contain many statements and footnotes that cast doubt on parts of the Bible. If you need examples, just look at the statements they have for the traditional conclusion of St. Mark’s Gospel (Mark 16:9-20) and the Pericope Adultarae (John 7:53-8:11).

Why those statements and footnotes? You can read my articles Bethel: A treatise on the theological reasons to reject most modern Bible versions (bethel-sg.com) and Bethel: A treatise on why I read the Authorised Version (KJV) of the Holy Bible (bethel-sg.com).

It is without doubt that those statements and footnotes would cause the reader to doubt the infallibility and Divine Preservation of the Word of God. The authority of the Bible to the reader, and the faith of the reader would be affected.

Therefore, those statements and footnotes in the ESV, NIV, and other modern English versions would be a simple reason for you not to read them.
