According to E.P. Sanders, who initiated the New Perspective on Paul with his 1977 publication "Paul and Palestinian Judaism", Paul saw the faithful redeemed by participation in Jesus' death and rising. Though "Jesus' death substituted for that of others and thereby freed believers from sin and guilt," a metaphor derived from "ancient sacrificial theology," the essence of Paul's writing is not in the "legal terms" regarding the expiation of sin, but the act of "participation in Christ through dying and rising with him." According to Sanders, "those who are baptized into Christ are baptized into his death, and thus they escape the power of sin [...] he died so that the believers may die with him and consequently live with him." By this participation in Christ's death and rising, "one receives forgiveness for past offences, is liberated from the powers of sin, and receives the Spirit."
