@ aqwesed - You claimed (as most/all trinitarians do) "But because Jesus was both God and man in one person..."
1) Do you disagree/believe this: Matthew 20:28 - “‘For this is how the Son of Man came… Not to be served, but to serve and to give his life as a ransom for many.”
2) Do you disagree/believe this: 1 Timothy 2:5, 6 - "...a man, Christ Jesus, who gave himself a corresponding ransom for all."
3) Do you disagree/believe this: 1st Corinthians 15:21,22,45 - Jesus replaced Adam as mankind's life-giving ancestor, with the whole human race owing their life to him, not to Adam. That will include everyone who is resurrected, and all those who survive the end. Isaiah 9:6 confirms this, by prophetically calling Jesus, “Everlasting Father.”
If Jesus' ransom corresponds
to what Adam lost, it logically follows (if your claim is true)
that Adam himself must have been "fully God &
fully man," otherwise, Jesus' ransom price was far, far,
greater than what Adam forfeited, and not "corresponding.".
Have you ever heard of such an anomaly with a ransom?
When can a ransom repurchase price ever be greater or lesser than what was lost?
If you can, please provide scriptural references if you disagree with anything here.
