“all authority in heaven and on earth.” God has set Jesus Christ as His second-in-command, his under-ruler, and given him all authority to administer His creation (Matt. 28:18; Eph. 1:18-22). He has made Jesus, “Lord” (Acts 2:22). Given that, what are some of the things that Jesus is doing now? Jesus is the head of the body of Christ, directing and guiding it (Eph. 1:22-23; Col. 1:18). Jesus gives the gift of holy spirit to people when they get saved, and thus he adds to his body (Acts 2:32-33; 2:47; Matt. 16:18). He supports his body, the Church, and causes it to grow (Eph. 5:15-16; Col. 2:18-19), and he organizes it, for example, by creating leadership positions (Col. 1:15-19). Jesus sets people in their personal ministries (Eph. 4:7-8, 11). He gives revelation to people (Gal. 1:11-12; Acts 9:10-17; 16:7; 18:9). He is a wonderful counselor (Isa. 9:6).
Jesus also ministers through his angels (Rev. 1:1). He prays and intercedes for us (Rom. 8:26-27, 34; Heb. 7:25). He protects us from evil (2 Thess. 3:3). Jesus heals people (Acts 9:32-34). He gives grace and peace to us (1 Cor. 16:23; Eph. 1:2; 1 Thess. 5:28). He is with us in our trials and suffering (Acts 9:4; Rom. 8:26). We can fellowship with Jesus (1 John 1:3), and we can pray to him for support (John 14:12-14; Acts 7:59; 1 Cor. 1:1; 2 Cor. 12:8-9). Jesus will raise us from the dead (1 Thess. 4:15), transform our bodies when we are raised at the Rapture (Phil. 3:21), and be our judge on our Day of Judgment (John 5:21-29; 2 Cor. 5:10).
“has been given to me.” This is one of the many verses that make it clear that Jesus Christ is not God. If Christ were really God, and co-equal and co-eternal with the Father as the Trinitarians teach, then it is illogical to say Christ was given authority. God, by definition, has authority.
Jesus is a man, and the authority he has was given to him by God and is not a function of his “divine nature.” The wording of Matthew 28:18 is, in actuality, a refutation of the Trinity. Jesus is that man to whom God gave “all authority.” In contrast to Christ, there is no verse anywhere that says “God” was given authority. God has all authority, and delegates it to others. Although there are some Trinitarians who teach that Jesus divested himself of his authority when he was incarnated as a human, this verse is after Jesus’ resurrection, and all Trinitarians affirm Jesus had his full position as God after he was raised from the dead, which was the case in this verse.
The Trinitarian refutation to the Scripture saying that “God” gave Jesus his position and authority, such as in Acts 2:36, which says, “God has made Jesus both Lord and Christ,” is to say that “God” means the Father. But there is no evidence for that; it is an assumption to support the doctrine and not what the Bible actually says. If we simply read the Bible as we would normally understand it, then “God” does not have to be constantly redefined. Jesus is the man, Jesus, and “God” is God.
There are many verses that say Jesus was given what he had from “God.” These include that he was “given” all authority (Matt. 28:18), “made Lord and Christ” by God (Acts 2:36); and that God “placed” everything under his feet and “appointed” him to be Head of the Church (Eph. 1:22). The most natural reading of the Bible is that “God” is the Father, and Jesus is the human Messiah, and “God” does things for Jesus, but “God” never does things for “the Father” because He is the Father.
Another reason that Matt. 28:18 disproves the Trinity is that if “God” is made up of the Father, the Son, and the Holy Spirit, then by definition Jesus cannot have “all authority.” By virtue of being “God,” the Father and Holy Spirit would both have equal authority with Jesus. In fact, it is part of the standard definition of the Trinity that the Father, Son, and Holy Spirit are “co-equal.” The only way Jesus could be given all authority would be if he were not God, but the Messiah, God’s chosen ruler, and the Father had entrusted him with all authority, just as God gave Jesus the authority to judge on the Day of Judgment (John 5:22).
