Why do you think they were given?
Luke 9:1-2 “When Jesus had called the Twelve together, he gave them power and authority to drive out all demons and to cure diseases, and he sent them out to proclaim the kingdom of God and to heal the sick.”
They were primarily for outside the Church.
They were not given to create a hierarchy.
They were always for mission.
They certainly were never intended to make charisma the king.
When these 2 gifts never leave the Church community then they evolve into something they were never created to be.
The purest form of them can be seen facing headlong the kingdom of darkness, the broken people of this world and those who cannot fix themselves and need Jesus.
Power and Authority were given by Jesus for mission. When mission is missing so is Power and Authority and what you have in its place is something ugly.
