Wrong on so many levels I'm not sure where to begin. If you really, really think this is about sola scriptura you are so wrong.
It is about sin. Plain and simple. It is the same justification that the pedophiles in the RCC have used to "normalize" their behavior. And that also is sin and the RCC needs to do something about it.
So you see, in spite of having all that "tradition" and other non-Biblical teaching the RCC espouses, it didn't stop those priests now did it.
This man should be dealt with in accordance with the outline Paul noted in the NT. He needs to be given an opportunity to repent and be forgiven. If not, then he is out of fellowship with the body of Christ.
All of us believe scripture is holy. No one got transgender preachers from scripture. In Mosul Christians are being slaughtered by ISIL forces. They are Syriac Orthodox and Chaldean Catholic. We should pray for them.
And as a fellow Christian I ask you, what possible contribution can this comment make to the discussion?
