So 99% versus 1% of the Greek texts of 1 John is missleading? I do not think so,
Ok so I pulled up some old notes of mine on 1st John 5:7.
First of all only 5 manuscripts that even contain 1st John period are from 7th century or earlier.
It is quoted by Tertullian (200AD), Cyprian (250AD), Priscillian (350AD), Idacias Clarus (350AD).
Jerome said in his day that 1st John 5:7 was being removed from manuscripts by the Arians.
1st John 5:7 is found, in the Old latin, the Syriac, the Armenian, the Georgian, the Slavonik, and is found in at least 10 Greek manuscripts, and at least 6 old Latin manuscripts.
John Welsey in his day said that there were more manuscripts that contained 1st John 5:7 than do not.
Gill said it was in many old latin manuscripts of his day.
Robert Dabney, Matthew Henry and Princeton scholar Edward Hills all believed that removing 1st John 5:7 created poor grammatical structure in the Greek.
So to say that 99% of Greek manuscripts do not have 1st John 5:7 may technically be true, however a large percentage of Greek manuscripts do not have 1st John chapter 5 period. So while the stats may be correct, the presentation of those stats are misleading.
A better question would be what percentage of manuscripts that contain 1st John chapter 5 have the 5:7 vs the ones that have 1st John 5 and do not have 5:7, but with this you
Also have to take into account church fathers quotations and that all the manuscripts of other translations like Latin and others are a witness to a text that they were translated from which contained 1 John 5:7.
To say that 5:7 doesnt belong just because “99% of Greek manuscripts dont have it” is misleading and lacks evidence of critical thinking. Unless you are prepared to cut 1 John chapter 5 out of the bible for the same reason and logic then you are being inconsistent and contradictory.
