I think if you would examine the language more closely you would see that statement was in reference to the book it was written in ... Apocalypse or Revelation. You might want to see St. Paul in regards to Sola Scriptura. —
2 Thessalonians 2:14
Therefore, brethren, stand fast; and hold the traditions which you have learned, whether by word, or by our epistle
I repeat, we don’t need any new “revelations” from people supposedly getting messages from God. Just read the Bible - and believe it.
