One could bring you to the baptism of Jesus were you would see Jesus being baptized, the Father Speaking, and the Holy Spirit descending, but for know, I'll steer away from the Gospels.
Instead lets go to Acts. I know a lot of Oneness people like using the book of Acts since it's "historical", and a practical way of walking out the gospel truths.
In Acts 7 we read about the first martyr of the Church. What we know of Stephen is little. He was a man full of faith and of the Holy Spirit, He was of a good repute, and was willing to serve in the daily distributions of the church as was needed.
We also know from Acts 6 the he was full of grace and power, doing great wonders and signs among the people. We also know that his opponents could not withstand the wisdom and the Spirit with which he was speaking.
Luke gives Stephen a lot of space in Acts, he gives Stephen a chapter and then some. Stephen also gives the longest ‘sermon’ in the book.
Summary: Stephen was a man of God who was able by the Holy Spirit to do great miracles and preach/refute those who apposed the Gospel of Christ.
Now we come to the end of this godly mans life, he just finished a historical overview of Israel history, and then rebukes the Jews, which in a way, sentenced him to death. It is here we pick up.
Acts 7:54-60
54 Now when they heard these things they were enraged, and they ground their teeth at him. 55 But he, full of the Holy Spirit, gazed into heaven and saw the glory of God, and Jesus standing at the right hand of God. 56 And he said, “Behold, I see the heavens opened, and the Son of Man standing at the right hand of God.” 57 But they cried out with a loud voice and stopped their ears and rushed together at him. 58 Then they cast him out of the city and stoned him. And the witnesses laid down their garments at the feet of a young man named Saul. 59 And as they were stoning Stephen, he called out, “Lord Jesus, receive my spirit.” 60 And falling to his knees he cried out with a loud voice, “Lord, do not hold this sin against them.” And when he had said this, he fell asleep.Remember this is a Historical account. Stephen is full of the HOLY SPIRIT, he looks up into heaven and sees the glory of God. JESUS is standing at the right hand of GOD, and then Stephen repeats this SON of MAN standing at the right hand of GOD.
There is three different ‘persons’: The Holy Spirit is in Stephen, Jesus/Son of Man (a term Jesus applied to himself in the Gospels) is Standing. Were is he standing? In heaven next to and at the right hand of God.
Remember this his a historical account of the Gospel being walked out in every day life within the early church. Stephen sees both the Son, and the Father in heaven, and is at the same time filled with the Spirit.
We see all three of the God head. The Father, Son & Holy Spirit. Notice All three are present at the first martyrs death. Stephen doesn’t see just God, or just see Jesus, he sees both.
Also notice the singular usage of the word God “Glory of God” and then the other Nouns used. Either this is a picture of God, filled with the Spirit, Jesus, God the Father, or you left to believe that the Spirit is just a force, Jesus isn’t really God since he only stands next to him in heaven.
Yes I agree that the word Trinity is not used in the bible, but what it represents is. Sometimes one needs to use extra biblical words to help frame a correct meaning of a biblical concept because words can be slippery things. For example: if I asked a Mormon, Catholic, Pentecostal, or a Jehovah witness are you a Christian the all would say yes. It’s only till they say Mormon, Pentecostal, or catholic that I now were their coming from and if they really are “in” the faith.
