That's the point...You're reading the bible wrong...And you come up with a lot of false junk by reading it wrong...
What the non-Catholics here do is to show you, with the actual scripture where and why you are wrong...
We back up our doctrines with scripture...You back up your doctrines with your religious tradition...
And since you don't, and can't back yourself up with scripture, why try to do it??? You take a verse like Matt. 16:18 and create a religion out of it, when in every instance in the entire books of the scriptures, the rock is Jesus Christ...
But back to your point, Yes, Jesus' flesh was in a sinful state...Jesus did not lie, if you look at it that way...
1Pe 1:24 For all flesh is as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away:
Rom 8:3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:
ALL flesh since Adam is corrupt...It has a proclivity to sin and it gets old and dies...Jesus started out as a baby, grew to a young man and would have died of old age had He not first been murdered...
Rom 8:4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
And Jesus was the Chief walker after the Spirit...
Rom 13:14 But put ye on the Lord Jesus Christ, and make not provision for the flesh, to fulfil the lusts thereof.
And that's exactly what Jesus did...Jesus says he was tempted in every way we are...That means with money, lust, power and every thing else under the sun...Jesus' flesh was obviously under the same curse as everyone else's...
So yes, in that sense, Jesus was correct when He said ALL have sinned...
Is it part of your doctrine that original sin is carried on the Y chromosome or is that somebody else?
