Right you are my friend. My excuse? Old Age and carelessnes. :-)
I should have said Luke was among those who believed the Apostles had the God given authority to name their successors. I am not among those who believe so but, then, I am one of those "off the reservation" Unitarians. I rather think the number "12" is important and was reserved to Jesus alone.
Whether Luke was present or not I don’t how one would determine but if Matthias was NOT to be counted among the 12 then who would be? No other person is appointed by Christ to be so numbered and even Paul did not count himself among the 12.
“I rather think the number “12” is important and was reserved to Jesus alone”.
I agree and therefore must ask, ‘If not Matthias, then who did Christ choose to fill out the number 12?’ And if he did, when and how?
The way I see it is that Luke just recorded what happened when Peter took matters into his own hands.
I don’t know that Luke voiced his approval or disapproval, or his opinion on apostolic succession at all.
