I think I am going to have to jump on the bandwagon of those who think that statement is at odds with the Christian understanding of the Trinity. Maybe you should explain what you mean, because on the surface that is the kind of statement I would expect from a Jehovah's witness or maybe a Mormon.
The first thing I will say is it is beyond ANYONE's understanding...But people don't let that get in the way of their apparent need to understand...And when the understanding can't be found, people turn to their own reasoning and human logic to explain it...
Joh 16:7 Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.
Joh 14:16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
Joh 14:26 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
Joh 15:26 But when the Comforter is come, whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, he shall testify of me:
These are familiar verses...And they are not complicated...When Jesus leaves, the Holy Spirit shows up...And Jesus sits at the right hand of the Father...
Very clearly, there are three...
Joh 10:30 I and my Father are one.
Joh 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
This is just a small sampling of the scripture on the issue...
People get so hung up on understanding the Trinity, they tend to dis-believe the scriptures that speak of the Trinity...
We were made in the image of God...We have a body, a soul and a spirit...But yet to look at us, all you see is one...
Mat 26:39 And he went a little further, and fell on his face, and prayed, saying, O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt.
Jesus wasn't speaking to Himself...But yet;
Joh 14:9 Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Shew us the Father?
It's a mystery...It has not been revealed to ANYONE...There are 3, but they are one...That's what the scripture says and I believe it...I'm not required to understand it...
