>>636738It's not about the crucifixion itself, it was a sacrifice to absolve the sins of humanity.
"for this is My blood of the covenant, which is being poured out for many for forgiveness of sins"
- Literally Jesus (Matthew 26:28)
You see in the old testament sins were absolved by giving offerings to God, sacrificial lambs and whatnot. Jesus was the sacrificial passover lamb for all of humanity.
You know if you actually listen to direct quotes from Jesus in the gospels, you'll see something was truly special, no one else on Earth has ever been recorded talking quite like him. Maybe you can ignore Paul, but Jesus has such a convincing divine authoritative manner of speech.
