If that's how you want to think about it, rock on. I prefer to read the plain scripture and believe it.
I myself would have said "OK,I am boss now and I am telling you that the Son of God told me that He would send me the Holy Spirit to help me guide you. And He did and you better start toeing the line,stop misbehaving and start loving one another and forgiving each other or you are going to Hell in a hand basket".
How would you have handled it?
If it said that, then that's how I would believe.
Peter never had the monopoly on the Holy Spirit. I do not diminish Peter's Apostleship in any way. If Peter was top dog, though, why did they roll the bones to choose between Barsabas and Mathias? Why didn't Peter just decide it?
Act 1:26 And they drew lots for them, and the lot fell to Matthias; and he was added to the eleven apostles.
"Act 1:26 And they drew lots for them, and the lot fell to Matthias; and he was added to the eleven apostles."
FWIW, after he was selected we never heard from him again. I think that is a good illustration of what God thinks of man made successors.
