If God can be “one,” with the two Persons of the Father and the Son, adding a third Person to the Godhead should not particularly add more difficulty. We are talking here about the Holy Spirit.1
Read Genesis 1:2. What does this tell us about the role of the Holy Spirit, who appears so early in the biblical record?
How does Matthew 28:19 draw attention to the three members of the Godhead?
Three Persons of the Godhead are mentioned when Jesus instructs how new believers are to be baptized. Indeed, this baptismal “formula” is still used in most Christian baptisms today. The person who has chosen to follow Jesus is baptized into the “Name” (singular, not plural, in the Greek), though three Persons are included. Three Divine Beings are viewed as One.
At the baptism of Jesus, all three Persons of the Trinity appear together. Read Mark’s dramatic description of that baptism (Mark 1:9–11). Mark’s description of the heavens as “parting” (vs. 10, NKJV) would be better translated “torn open” (NIV). Mark draws attention to all three Members of the Divine Godhead in an awesome revelation of God that affects even nature itself.
As with Jesus, the work of the Holy Spirit is linked with and attributed to the actions of God. Review the following portrayals of the Holy Spirit’s actions:
1. When announcing the birth of Christ, the angel tells Mary that her Child will be called “holy” because the Holy Spirit will come upon her (Luke 1:35).
2. Jesus claimed that the Spirit of the Lord was upon Him, anointing Him to preach (Luke 4:18).
3. He also claimed to be driving out demons by the Spirit of God (Matt. 12:28).
4. The Spirit, who is to carry on Christ’s work after His departure, is another Counselor of the same kind (John 14:16).
5. Jesus breathed out the Holy Spirit upon His followers (John 20:22).
Christ and the Holy Spirit are intimately linked with each other’s ministry. Moreover, there are biblical references that identify the Holy Spirit as God. Read Acts 5:1–11. How does this incident help us understand the deity of the Holy Spirit, as well?
