“the original Greek doesn’t imply that whatever Peter says is right and wrong will change Heaven’s mind on what is right and wrong”
The fact is, that Peter’s judgments will be consistent with Heaven’s; not that his judgments will change Heaven’s mind.
So how is that different from other Christians? Aren't we all supposed to educate others on what's right and wrong? For example (I know, it's that pesky Bible again LOL):
Galatians 6:1 -- Brothers and sisters, if someone is caught in a sin, you who live by the Spirit should restore that person gently. But watch yourselves, or you also may be tempted.
How can we fulfil that teaching from Paul unless we all speak at least some level of judgement? When we do it, we must get it right (speak Heaven's rules, not our own).
Maybe it's time you looked at my tagline. Here it is in context:
1st Thessalonians 5:19-22 -- 19 Do not quench the Spirit. 20 Do not treat prophecies with contempt 21 but test them all; hold on to what is good, 22 reject every kind of evil.
I've tested the teaching of "papal supremacy" and "apostolic succession" and find it horribly audacious and blasphemous to Christ and His Word. Papa Frank is Exhibit A on how dangerous it is to put into man's hands too much control over God's church.
