Like you, I see no other harmony.
When Jesus was called "Good Teacher" Jesus specifically pointed out to the ruler that only God is good.
We can have many teachers, but if only God is our good teacher, what does that tell us about Jesus?
"Good in the Supreme sense" ?
So who is our good teacher in a non-supreme sense, and where can we find more about these lesser "gradations of good" that were attached to Jesus.
Also, this brings up another problem. Not for Trinitarians of course, but for Unitarians.
The suggestion is that "Good" is on some sort of sliding scale. Eli G, another JW, gave a good example of this when he stated:
I'm not seeing where Jesus "is not good to the same degree that God, his Father, is good".
In fact, I see Jesus is exactly the same "good" because he reflects the Father perfectly:
So either Jesus is reflecting God's glory and making an EXACT representation of God's "very being", or he is not.
Our JW friends are pretty much on board saying Jesus does no such thing, and that Jesus' representation is a bit on the shaky or shady side.
So we either have a shaky Jesus, or we have apostles who speak in hyperbole when talking about Jesus, or perhaps what the JW's say is true and the fault is not Jesus, but God's, because Jesus is simply reflecting what God is generating.
Can one of our unitarian friends tell us which Jesus is really Jesus?
Is he the exact representation of God, who is good, or is he reflecting something else, that is perhaps less good?
