BUT....I do get your point.
I know until the 1500’s depending on where one lived in the world, one learned about Jesus either from the Eastern orthodox churches or the western Roman catholics. The writer of post 2 needs to remember that. After the 1500’s the Orthodox and the roman Catholics still need to remember that Protestants aren’t going away and Christ accepts them as his children too...at least the ones who truly have encountered his spirit and have been washed in his blood.
That is part of what my point is. Christ can and will help us all bridge our differences! We are all in for a lot of surprises...and heartbreaks...but then the joys of his presence in bodies made incorruptible!
