Actually, Christ was killed because the treasurer of his group betrayed him after a humiliating disagreement on disbursement of funds to benefit the children of unmarried women. The more things change the more things seem the same. When he realized what he had done, Judas committed suicide. The jealous high priests whose minions hammered Christs hands and feet to a cross were a sorry lot of leaders whose power had gone into their swollen heads.
Regardless, Christ the Lord forgave all of them with his prayer to the Father God, "Father, forgive them, for they know not what they do." And he forgave them as they were hurting him to a physical, but not a spiritual, death. Christ rose from the grave to visit his disciples to charge them with good news that Christ, in accordance with Isaiah's prophecy, was still with us to be loved by us triunely as God the Father, God the Son, and God, the Holy Spirit. The exact words are found in the Biblical Book of Isaiah, Chapter 9. Thousands of years ago, and Jesus fulfilled that prophecy. Even so, God does not forsake his people, the first of whom were parents of the human race, Adam and Eve, then their generations who became known as the Hebrew people or Jews as they are commonly called today. God would not cut himself off completely from his first family of humans, the Jews. And through Jesus Christ, the son of God, all humans may receive God's grace and a place at the table along with God's first family who dwell in Heaven according to their faith. As God told Moses who wanted to know his name, God said for him to call him, "I am who I am..." IOW, God's grace is through himself and no other according to Christ the Lord.
