Another school, called Ebionites, could not believe that man could be united with deity, and sought to find a way to depreciate Jesus as a man, and so these were heresies that threatened the faith, and the church had to summon the ability to meet these dangerous threats by church councils, so in the fourth and fifth century you have six church councils, one of them is the council of Nicaea, they take their name from their location, about the issue of deity and humanity, and it brought some resolution, but it raised new questions, so then there was a subsequent, the council of Chalcedon, you don't have to know all this, though it's interesting in itself as church history, and they wrestled with the great questions, and out of that second council came a statement, I'll be able to read it to you somewhere here, that Jesus is both man and God, two persons of the same substance, and there's a Greek word for substance, and even the word persons was something that the Greek mind in that generation was able to conceive as answering the issue, but how there could be a union between the two persons could only be answered that they were the same substance, they were deity, they were God, so that has more or less been the prevailing theological foundation for understanding the mystery of God in the flesh, two persons united, but of equal substance with God, and that's why Jesus could be acknowledged as Lord, because his own testimony and the witness of the early church recognized his Lordship, and if he's Lord, he's also therefore God, so how God himself could be manifest in flesh with man seems to be itself heretical, and of course Jews to this day have been offended by that premise, how could a holy God be joined with man, seems to be an apparent contradiction, but it's a mystery, so I'm raising the question, what are the implications, yes it has served the purpose of providing atonement that required the death of a man who is also God, but what, beside rendering that service, what's the implication for us of the issue of deity and humanity somehow united together, is there an implication for us, are we a continuation of that mystery, is God in us, in our flesh, why do we say Christ in us, the hope of glory, why does Paul keep talking about in him, in him, in him, I live and move and have my being, for me to live is Christ, is a man reiterating the mystery as it pertains to himself, so it's not just that Jesus set something forth, but set something forth in which the church is to continue, and if it required the union of deity and humanity to serve the purposes of atonement, what is required to serve the purposes of God's glory, and how does that work, how did it work for him, what of his decisions and his conduct issued from his deity, and what of his conduct issued out of his humanity, and is there any way really to tell, could it be that even his miracles did not issue out of some omnipotence that he brought with him as God, but out of a faith, and a union with the father by faith through prayer and devotion, see these are remarkable questions, because if he acted in power only out of his deity, then we cannot hope to emulate him and that we're not God, but if he acted out of his humanity by faith, then there are implications for us, and maybe even the other way too, in what degree is God in us as the hope of glory, and to what degree can that God in us be appropriated, and given opportunity to express himself through our flesh as he expressed himself through the flesh of Jesus, so this is what we're going to consider in these great questions, it's not just an abstract theological or doctrinal consideration, the implications are astonishing, and the church has not rightly even begun to consider what this mystery of incarnation means for us, how can we ourselves continue in it or be the expression of it, and if we're not conscious of that mystery, and ourselves in a privileged place to express it, how shall we?
