What does the Catholic Church teach about the Suffering Servant?
The servant of God in Isaiah is a Hebrew figure that either represents the nation of Israel or is a leader of Israel, hence possibly Messiah.
This servant of God heals by suffering for others (Is. 53), and this understanding opens the door to interpreting Jesus’ death as something undergone for the sake of others. A martyr dies for others insofar as his or her cause will benefit others. Jesus is understood this way as well as in a mysterious way that his death affects the cosmic moral order.
He is world redeemer in the minds of Christians.
