As we explored previously in our study, the idea of the Trinity speaks to the fact that God is three in one, Father, Son, and Holy Spirit. Scripture testifies that the Holy Spirit proceeds or comes from the Father and Son. In John 15:26, Jesus said the Advocate, or Holy Spirit, would be sent by the Father in the name of Jesus. In John 16, Jesus spoke of personally sending the Holy Spirit, and in Romans 8:9 the Holy Spirit is referred to as the Spirit of Christ. Galatians 4:6 reads, “And because we are God’s children, God has sent the Spirit of his Son into our hearts, prompting us to call out, ‘Abba, Father.’”
In this way, Scripture shows us that the Holy Spirit is sent by both the Father and the Son.
In the third century, as the church was working out their understanding of theology, there was a debate about whether the Holy Spirit was truly God. Ultimately, the church confirmed that the orthodox or right belief was that the Holy Spirit is God and the Spirit is to be worshipped as God. Scripture passages like Matthew 28 helped lead the church to the understanding that the Holy Spirit is fully God. Matthew 28:19 is part of what we call the Great Commission. Jesus says to His followers, “Go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit” (NIV). All believers are to be baptized in the threefold name of God. In this way, the Holy Spirit is seen as equal with the Father and the Son.
We also see this in 2 Corinthians 13:14. The apostle Paul wrote a benediction, or blessing, to the church in Corinth: “May the grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with you all.” God the Father, God the Son, and God the Holy Spirit are all set on equal standing together, one God worthy of all our worship.
