Apostles saw Jesus face to face after Jesus chose 12 from all his disciples.
There is no Apostolic succession in scripture ... none.
(BTW -- "succession" wasn't mentioned or suggested above)
Why shouldn't they???
Through Christ's promises and prophecies...
....and each recording of the Great Commission...
The works and wonders of the Holy Spirit have always been...
...And remain God's endorsement for the heralding of the Gospel...
....As well as the affirmation of HIS high calling in the life and expressions of HIS ministry in the life of HIS humble servants.
The principles premises of Ephesians 4:11ff are also germane...
Enjoy your day.
