Surprising 1 John 5:7 evidence: At Faith Baptist Church in Homosassa, Florida, Dr. Phil Stringer mentioned he visited/went to the "museum to the Waldenses" in Valdese, NC; and Phil Stringer said they had multiple old, Latin manuscripts of 1 John 5:7 in their manscript room. (The only museum in NC/North Carolina that is the "museum to the Waldenses" is called Waldensian Heritage Museum).

Here is the first video link on Valdese (in North Carolina) museum manuscripts of 1 John 5:7 (watch from 24 minutes 55 seconds to 28 minutes 34 seconds): https://www.youtube.com/live/2qGw9LxuW30&t=1495

Moreover, Dr. Phil Stringer mentions that a Greek monastery in Greece told him that they have about 20 manuscripts with 1 John 5:7 and 1 John 5:8 (including the "Johannine Comma")

💥In addition, Dr. Phil Stringer said [in the same video] that he heard from a monastery in Greece that said to him they have 1,100 Greek manuscripts that people in the West do not list, & that monastery alone had 20 Greek manuscripts with 1 John 5:7-8 in it. On the monastery in Greece, Phil Stringer also said "I sent over a question to him how many of them are majority texts? how many minority texts? [The man at the monastery] said they're all majority texts we would not have bothered to have saved ones who are minority texts because we knew they were phony" before asking about how 1 John 5:7 manuscripts the monastery in Greece had. Next Phil Stringer asked, " 'Do you have any manuscripts of First John? 'yes' 'Do they have first John 5 7 and 8?' And they had about 20 in that Monastery alone with first John chapter 5 verse 7 and 8."
