The super-irony is that Brian attacks me for making the exact same points against Barry Hofstetter! (Also James Snapp and Bill Brown.)
Rather than helping defend the pure Bible text, Brian is far more interested in attacking me for making sound, accurate defense arguments. His "sources" include the BVDB contras, who follow Bill Brown, who makes the SAME ERRORS!
On 1 John 5:7? I still would but it's not fresh in my mind right now, the Greek speakers would be interested if you can message to me. Regarding the passage as genuine, the most likely date such a passage would have stopped being read in churches would be during the Sabellian heresies. There's too many Latin forms for it to be of Latin origin. It's what we find in independent translations.
I don't feel you are in the position to criticize the Greek of others, even those you oppose, because you have no sure foundation for it. It is a very careless and harmful thing to do. A lot of problems are caused by people who can get on a Greek parser and think they can read it like English, when it can't be. And when corrected, they double down hard and form arguments even worse than they had before. Don't betray trust people may put on you.
