Two Scriptures that must be considered together in any Bible-based discussion of the dogma of the Holy Trinity are;
A: I and my Father are one. -- John 10:30
B: And the glory which thou gavest me I have given them; that they may be one, even as we are one. -- John 17
These two passages have to do with the oneness of the Father and the Son, and with the oneness that Jesus desires his disciples to have.
Jesus is explicitly saying that whatever the nature of the oneness that he and his Father enjoy is, then that same oneness should be shared by all his disciples.
It is not possible to believe that the of Jesus and his Father is that of physical inseparableness or of a common single identification that renders Father and Son incapable of being separated or uniquely identified apart from each other, for, if that were so, then Jesus would be pleading with the Father for all his disciples to be combined into one astronomically large single person, the result of which would be One God and One Man, making but two beings in the whole of existence, one Divine and one saved human composed of all saved saints since the world began.
It is impossible to make a special case out of God the Father, and God the Son, and God the Holy Ghost, when Jesus uses the exact same language to describe the oneness he seeks for all that would come to him to be saved.
The misunderstanding lies in the commonly accepted triune nature of three deities, Father Elohim, Son Yahweh, and Spirit, with the Son and the Spirit subordinate to the Omnipotent, Omniscient Father-God.
Of his subordination to his Father, Jesus says,
- "Why callest thou me good? there is none good save One."
- "My Father is greater than I"
- "Father, if it be possible remove this cup far from me. Nevertheless, not MY will but THINE be done."
Other passages also show the distinction between the Father and the Son.
