Curtis: "Your attempt at rebuttal ignores the fact that being sinless is the epitome of being good."
This response ignores these 4 facts:
(1) You ducked my point that Jesus felt the need to receive John's baptism of repentance and did so to "fulfill all righteousness (Matthew 415)," not to set a good example.
(2) Jesus had to "learn obedience through the things He suffered (Hebrews)," so that His ultimate perfection was a process acquired by trial and error.
(3) The 12-year-old Jesus rightly merits Mary's rebuke for leaving the family entourage near Jerusalem for 3 days without telling his parents where He was going, thus worrying then sick unnecessarily (see Luke 2:43-48). Thus, Jesus only gradually acquires God's "favor:" "Jesus increased in wisdom...and in favor with God (2:52)." By definition, then, Jesus had previously been in less favor with God.
(4) Jesus was tested on all points in the same way that we are, yet without sin.= (Hebrews 4:15)." Part of being human is the need to learn by trial and error. So Jesus' maturation involved many mistakes, but not sin because sin is the condition of separation from God and Jesus was never separated from God.
Jesus' implied teaching that God is the source of all goodness, so that Jesus' goodness is derivative from God's goodness.
Curtis: "If Jesus isn’t perfectly good, he isn’t qualified to die for sins."
A pontification without evidence! If Jesus is a divine incarnation, that fact is sufficient for Him to "die for our sins."
"Curtis: "And even if your claim was true that He is only the Son of God, and not God the Son, He still is MUCH MUCH MORE than merely a good teacher, which would still need to be pointed out."
Here you overlook my disclaimer that I accept the traditional doctrine of the Trinity. I am merely pointing out that your response to the OP on the basis of Scripture is inadequate.
