Baptism is introduced in the Gospels when John the Baptist begins his ministry as the forerunner of Jesus Christ. John's baptism was a baptism of repentance for Jews; he preached a simple message to the Jews that they were to repent of their sins in preparation for Kingdom of God and the coming of the Messiah. In Matthew 3:13-17, Jesus comes down to the Jordan River to be baptized by John. After being baptized, Jesus came up immediately from the water; and behold, the heavens were opened, and he saw the Spirit of God descending as a dove and lighting on Him, and behold, a voice out of the heavens said, “This is My beloved Son, in whom I am well-pleased.”
At the end of his earthly ministry, Jesus gave the command to his disciples to “Go, therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit.” As soon as they received the Holy Spirit at Pentecost, the disciples began to carry out that order. Known as the “Great Commission,” Mathew 28:19 is often quoted in an attempt to prove the trinity doctrine. As it is often looked at to be one of the few texts that fully demonstrate the Trinity, it provides the basis of what came to be known as Trinitarian baptismal formula
The greatest revealed mystery of the Christian faith is the Trinity; it is the central mystery of the Christian faith and of Christian life. God alone makes it known to us by revealing himself as Father, Son and Holy Spirit.

The Trinity is invoked over those who are to be baptized with the words from the celebrant: I baptize you in the name of the Father, and of the Son, and of the Holy Spirit , so that all who are signed in his name are consecrated to the Trinity and enter into communion with the Father, the Son and the Holy Spirit. They are prepared for this high dignity and led to it by the scriptural reading, the prayer of the community and their own profession of belief in the Father, the Son and the Holy Spirit.
Reading Scriptures reveals that in the New Testament, baptism is undertaken out of obedience by believers as way to identify themselves with the resurrected Christ, as well as an opportunity for God to work at strengthening their faith and encourage reverence among his people. Reviewing texts produced by theologians reveals themes which echo the words of the Great Commission in the New Testament. The relationship of Christians to God is a relationship to the Father, to Jesus Christ his Son and to the Holy Spirit, or to the Father, through the Son, in the Holy Spirit . Baptism unites believers with Christ through the Holy Spirit. Baptism also symbolizes the economy of...
