Sorry I didn’t respond promptly, my work sometimes keeps me from the pc for days.
I was raised, instructed in, and followed the trinitarian theory for my first 28 yrs (am now 53). The co-this, co-that, and co-everything, yet separate and distinct thinking is full of inconsistancies. When these snags pop up, the concluding point always is ‘it’s a mystery’.
**Jesus told his disciples, “to baptize in the name of the Father and of the Son and of the Holy Spirit” (Matthew 28: 19).**
My version has ‘name’ singular as well, but commas divide the titles (what trinitarians call names).
That’s part of what’s commonly called ‘the great commission’. All of the Lord’s commissions were great, including Luke 24:45-48 “Then opened he their understanding, that they might understand the scriptures. And said unto them, thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day: and that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem, and ye are witnesses of these things...”.
These men had been trained by the best, and responded by baptizing in the name of Jesus.
They knew that the saving name of the Father was Jesus. “I am come in my Father’s name...” John 5:43
They knew that the Son’s name was Jesus (multiple scriptures agree).
They knew that the name of the Holy Ghost was Jesus. “But the Comforter, which is the Holy Ghost, whom the Father will send in my name...” John 14:26
That’s why the apostles, who obeyed Matt 28:19 (and did not simply repeat a command) baptized in the name of Jesus.
The apostle born out of due time, Paul, baptized souls in the name of Jesus. Later he dealt with a Corinthian church that had saints bragging about who baptized them instead of glorying in the Lord: “Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul?” 1 Cor. 1:13
I consider the trinity description of God to be more confusion than mystery. However, I see on this thread that the Mormons definitely are heavyweights in the confusion category.
