You've really said a mouthful, Mr. Dave.
How much authority do you believe we, as Christians, possess,
and how might that manifest?
IYO...
Good question...hmmm.
Let me think 'out loud.' Not sure where this is going yet, hehe.
Rom. 13:1, There is not authority except from God. and Col 1:16, God created all authorities.
Jesus gave his disciples authority, sot as well as showing Jesus divinity, the disciples are given back a part of what was lost in the fall, or at least if it wasn't lost, then man's authority on Earth is re-asserted (cf. Gen 1:28).
Jesus taught a new teaching, which he did so with authority, Mark 1:27.
The Lord gave the apostles authority to build people up or bring people down (2 Cor. 10:8; 13:10). This to me seems to be in teaching, so it would seem that (in at least one aspect) the authority given to Christians is that authority to teach about Jesus. Jesus called the apostles, and he calls all of us (be that to ordained ministry or to Christianity as a lay-man), so we too are given authority by Jesus to some degree to teach about him, and to build people up or bring them down. As would naturally follow, all Christians are therefore given great responsibility on behalf of Christ. This itself reminds me of Luke 10 when Jesus sends the 70 out in front of him. The first impression the people have of Jesus comes through those sent by Jesus on his behalf, they too had great authority and responsibility given by Jesus.
I think this may be part of what is meant in the verse you give from Luke 10, about authority to trample on snakes etc... which comes on the joyful return of the 70. There is re-assertion of the authority given in Genesis about dominion over God's creation, and as such, great responsibility with that, although I don't think this re-assertion is the thrust of the verse, just an extra way of reading into it. I think the mention of the snakes etc... is a reference (easily understood by the 1st Century jews) to the OT, Deut 8:15, gives the impression of Jesus (again asserting his divinity) protecting his followers as He protected his people in the Exodus, as hard as things are, Jesus is there givin us protection and continually giving us authority over the rest of creation. Psalm 91:11-13, gives the idea that even with God's authority imparted through us, we are watched over and in the shelter of the Most High. With the authority to teach of Jesus and proclaim that he can forgive sin, this isn't always an easy task, but God is continually watching over us with care.
Here ends today's ramblings
