The Holy Trinity?

The Biblical Doctrine of the Trinity

The Holy Trinity. The term doesn't come up a single time in the Bible, but it's still thoroughly biblical. One God in three persons. Not three gods, one God, Father, Son, and Holy Spirit. All fully divine, uncaused, and eternal, but without division of nature, essence, or being.

Evidences of the Trinity are all throughout Scripture. In Matthew 3, after Jesus was baptized, the heavens opened up, and the Spirit descended on Him like a dove. Then a voice from heaven was heard saying, This is my beloved Son, with whom I am well pleased.

During the Last Supper, Jesus promised His disciples the Holy Spirit. Then He prayed, Father, glorify me in your own presence with the glory that I had with you before the world existed. After His death and resurrection, He commissioned His disciples to go and baptize in the name of the Father, and the Son, and the Holy Spirit.

We read in John 1 and Colossians 1 that the Father and Son were present at creation. And in Genesis 1 -2, we see the Spirit also. The Apostle Paul wrote that Christ and the Godhead are seen with Israel in the book of Numbers, where we also see the power of the Spirit.

Why Denying the Trinity Is Heresy

The Triune God is indeed one of those divine mysteries, but how necessary is it to believe? Well, to deny the Trinity is heresy. 1 John 2 -22 says, Who is the liar but he who denies that Jesus is the Christ?

This is the Antichrist, he who denies the Father and the Son. And since 1 John 5 -6 says that the Spirit is the one who testifies about Christ, denying the Father and Son is also to reject the Spirit.

The person who denies the Trinity is a liar and an Antichrist, when we understand the text.
