That I will agree with but without those sins would His sacrifice be necessary? No, so to lay blame by some is flawed, is my only point here. They can settle blame assignment when/if they go home and ask Him themselves who was to blame? They might be surprised at the answer, which I suspect is all of us.
Ultimately it was a voluntary sacrifice. The Lord always had the right to tell all to go to hell as the devil’s slaves, but His own love forbade Him.
And I mean, what did Christ beg on that cross?
For these “pious Pius” folks to carry on like that (unless they don’t, and if they don’t then wonderful) would bespeak, at best, an extremely dilute Christ-ianity (and I hyphenate the word for emphasis).
I know without shadow of doubt that my own personal sins drove the nails into Christ's feet and pushed the spear into His side. Without His redemptive work, my fate is hell.
My only point is that I, and every other sinner is GUILTY! To say we are not guilty because God knew what we were going to do is simply wrong.
And anyhow. If whatever Christian group bid him farewell to eternity had any class, they’d do what Christ did. Pray for the forgiveness of all sinners.
