In the New Testament the distinctness of the persons of the Godhead is made clearer. In Matthew 28:19, Jesus taught the disciples to baptize in the name of the Father, and of the Son, and of the Holy Spirit which underlines their oneness. When John baptized Jesus in the Jordan River the heavens opened up and the Holy Spirit in the form of a dove descended upon Jesus.
In Mark 1:10-11 God then spoke directly from heaven saying “You are my Son, whom I love; with You I am well pleased.” This was a clear manifestation of the Trinity involving all three persons of the Godhead at the same time. The Trinity is also referenced in the following Scriptures:
Luke 1:35 – And the angel answered and said to her, “The Holy Spirit will come upon you, and the power of the Highest will overshadow you; therefore, also, that Holy One who is to be born will be called the Son of God.”
John 14:16 (Jesus speaking) – And I will pray the Father, and He will give you another Helper, that He may abide with you forever.
2 Corinthians 13:14 – The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy spirit be with you all. Amen.
Romans 1:7 – To all who are in Rome, beloved of God, called to be saints: grace to you and peace from God our Father and the Lord Jesus Christ.
The Persons of the Trinity never act independently or in opposition to one another. The Son and the Holy Spirit are subordinate to the Father but they are not inferior. It’s a matter of relationship but not of nature. All are equally divine. The Spirit of God is said to proceed from the Son as well as the Father. The Father is the One by whom the Son is begotten and from whom the Spirit proceeds.
Those who want to make Jesus and the Holy Spirit lesser deities than God the Father must understand that while God the Father was the architect of the universe it was Jesus who actually built the universe and the workman was the Holy Spirit. The Father originates, the Son reveals and the Spirit executes. Creation is from the Father through the Son by the Holy Spirit. The Trinity has always existed with each Person co-equal and co-eternal. In my blog I’m comfortable using any of the three Persons of the Trinity interchangeably when I speak about God because all three are God. It all depends on the circumstances.
