An interesting explanation on Matthew28:19
What About Matthew 28:19?
Matthew 28:19 is a sometimes misunderstood biblical passage with
regard to the Trinity doctrine. "Go you therefore, and teach all
nations, baptizing them in ['into,' Greek eis] the name of the
Father, and of the Son, and of the Holy Spirit."
Remember the important principle that the Bible interprets the
Bible. What this particular passage shows us is the proper
baptismal formula, not a description of the nature of God.
Notice Acts 2:38: "Then Peter said to them, 'Repent, and let every
one of you be baptized in the name of Jesus Christ for the
remission of sins; and you shall receive the gift of the Holy
Spirit." After real repentance and being baptized, the example from
Scripture is that a minister lays his hands on the repentant person
and he or she receives the Holy Spirit directly from God (Acts
8:14-17).
Important as it is, baptism alone is not sufficient. It must be
followed by the biblically mandated laying on of hands for the
receiving of the Holy Spirit—the seed of eternal life (Acts
19:1-6). We cannot partake of God's nature (2 Peter 1:4) without
first being begotten of the Father by the Holy Spirit, which
imparts that divine nature.
Christ's instruction in Matthew 28:19 presumes that, before being
baptized, believers will learn of God the Father, His Son and the
Holy Spirit. At baptism, they enter into a personal family
relationship with God the Father and the Son through the Holy
Spirit, thereby receiving the name of God (compare Ephesians
3:14-15). This is the message of Matthew 28:19.
