There is one Gospel but four ways of understanding it. These correspond to the four “Gospels”, that is, the Gospel according to Mathew, Mark, Luke, and John. They each emphasize different aspects of the good news of Jesus Christ. For example, see Characteristic Differences of the Four Gospels (which Kregel Publications calls “Four Views of Christ”) by Andrew Jukes.
The fourfold Gospel includes a fourfold atonement corresponding to the key roles and accomplishments of Jesus Christ:
(1) Victor: He overcame death, hell, sin, and Satan, that is, evil and all its manifestations, without denying the rights of Satan and his minions. Christ is Lord, King, and Ruler of all.
(2) Sacrifice: He provided a way for God to forgive us without compromising righteousness. He did this by satisfying the requirements of justice on our behalf. Christ is Priest, Lamb, and Temple for all.
(3) Mediator: He restored our relationship to God, that is, overcame our alienation from God, without ignoring the development of our alienation. Christ is Prophet and Intercessor for all.
(4) Exemplar: He embodied the way, the truth, and the life of God, showing us how to live, what to think, and which actions to take. Christ is the Way, the Truth, and the Life.
