"Jesus handed over according to the definite plan of God"
Jesus' violent death was not the result of chance in an unfortunate coincidence of circumstances, but is part of the mystery of God's plan, as St. Peter explains to the Jews of Jerusalem in his first sermon on Pentecost: "This Jesus (was) delivered up according to the definite plan and foreknowledge of God." This Biblical language does not mean that those who handed him over were merely passive players in a scenario written in advance by God.
