Johannine "agency christology" combines the concept that Jesus is the Son of his Father with the idea that he has come into the world as his Father's agent, commissioned and sent by the Father to represent the Father and to accomplish his Father's work. Implied in each Synoptic portrayal of Jesus is the doctrine that the salvation Jesus gives is inseparable from Jesus himself and his divine identity. Sonship and agency come together in the Synoptic gospels only in the Parable of the Vineyard (; ; ). The submission of Jesus to crucifixion is a sacrifice made as an "agent of God" or "servant of God", for the sake of eventual victory. This builds upon the salvific theme of the Gospel of John which begins in with John the Baptist's proclamation: "The Lamb of God who takes away the sins of the world". Further reinforcement of the concept is provided in where the "lamb slain but standing" is the only one worthy of handling the scroll (i.e., the book) containing the names of those who are to be saved.
