Common Christian Question: ' Does anybody know of another person
than Jesus who is said to have claimed to be sinless (no "burdened soul")
himself and to atone for men's sins (to "bear another's burden")?'
Children are sinless, unless you believe children who don't survive go straight to Hell for not declaring Jesus as their savior.
Since children are sinless, then if we look into the Gospel of Matthew, all the children of Bethlehem bore the burden of Jesus, they died in the place of Jesus.
In Matthew 2:8 we see the jealous king Herod send out people to hunt down and locate Jesus.
"Then he sent them to Bethlehem with these instructions: "Go and make a careful search.."
In Matthew 2:13, a angel warned Jesus and his family that Herod was trying to find and kill Jesus;
"An angel of the Lord appeared in a dream to Joseph and said, "Herod will be looking for the child in order to kill him"
In Matthew 2:14, Jesus and his family hide in a different country to avoid being killed, now King Herod is still searching for Jesus and can not find Jesus so King Herod orders every boy in Bethlehem killed in a attempt to kill Jesus.
"He gave orders to kill all the boys in Bethlehem and its neighborhood who were two years old and younger-this was done in accordance with what he had learned from the visitors about the time when the star had appeared." Matthew 2:16
King Herod in the Bible did not go after Jesus in Egypt (which could easily have been done), because he assumed Jesus was still in Bethlehem, so King Herod murdered all the innocent boys in Bethlehem in hopes to also kill Jesus while Jesus safely stayed in Egypt.
Therefore there were Many who were sinless and bore the burden of others. Jesus was saved with the blood of the children of Bethlehem according to the Bible. They died so that Jesus could have life according to the Bible.
