From Numbers 16:
But Moses and Aaron fell facedown and cried out, "O God, God of the spirits of all mankind, will you be angry with the entire assembly when only one man sins?"
Moses exclusive mediator here?
Then Moses said to Aaron, "Take your censer and put incense in it, along with fire from the altar, and hurry to the assembly to make atonement for them. Wrath has come out from the LORD; the plague has started." So Aaron did as Moses said, and ran into the midst of the assembly. The plague had already started among the people, but Aaron offered the incense and made atonement for them. He stood between the living and the dead, and the plague stopped.
This is the verse you referred to originally. So was Moses the exclusive mediator here - or did he have some assistance from Aaron? You say not - so what exactly was Aaron doing?
I could give you my own answer to this conundrum but I'd rather hear a coherent explanation from you first.
Since Jesus was "God manifest in the flesh" he was the most fundamental teacher of all time. Everything he said was ultra orthodox, authentic, and original since he was the Source.
And yet he taught that it was ok to break the Jewish laws - the laws which He Himself was supposed to have given? He taught of an afterlife - of which there was originally no idea in Jewish thought - which is why the fundamentalist Jews, the Saduccees, didn't believe in an afterlife....
Christianity was originally a Jewish sect. When and how did it become ok to break away from their 'roots' and go a completely different direction?
Could it be that 'the light kept getting brighter' during and after the exile, through Jesus' time and then on into the early church?! Those darned liberals introducing all these Greek ideas?!!
Or has the Bible been corrupted by man?
