The Father's voice was heard AT THE JORDAN, was it not?
The Spirit descended on Christ IN THE JORDAN, right?
Jesus was in the waters OF THE JORDAN - correct?
OK, let's go over this again.
Yes, the Fathers voice was heard AT THE JORDAN, was it not?
Answer: yes it was heard by people on the earth, but the people heard it coming from the heavens.
So yes the people heard it on earth, but the Father was in the heavens when He spoke.
God the Father was not on the earth when spoke, he was in the heavens, right?
IOW, since God the Father was in the heavens at the exact same time that Jesus was on the earth being baptized, it means they cannot be the same person. Right?
The Spirit descended on Christ IN THE JORDAN, right?
Answer: yes, the HG descended on Christ AS HE STOOD ON THE BANKS OF THE JORDAN RIVER.
But as the HG was descending from heaven, there was obviously a time when the HG had not fallen upon Jesus. IOW there was a time when the HG and Jesus were not one. Right?
Jesus was in the waters OF THE JORDAN - correct?
Answer: you are correct? But God the Father was not in the waters OF THE JORDAN, correct?
And there was a time when the HG was descending from heaven that he was not in the waters OF THE JORDAN with Jesus.
Bottom line: Yes, all 3 of the Godhead were at the baptism of Jesus, but none of them were in the exact same place and the exact same time. It is true that the HG eventually descended all the way from heaven and eventually he did fall on Jesus and they became one. But God the Father never came down from the heavens to fall upon Jesus.
So, there is a Trinity, made up of the Father and the Son and the HG. But not in the form of Trinity that you interpret it to be. The baptism of Christ event, is far more in line with how the Church of Jesus Christ understands the nature of the Godhead, 3 distinct and separate persons. This is the only way you can have them at the same event, but not all 3 in the same, exact location at the event. The Trinity doctrine falls apart at the baptism of Christ.
So the baptism of Christ does vindicate JS. Not Athenasius.
