If you told me what your perception/understanding was, I would believe that that is what you believe.
Well my perception is drawn from John, as I suppose yours is, but I rather think you've jumped on that line and ignored the context of the Gospel.
Jesus says 'I and the Father are one' but
only to point out that such is not the case for His audience. Read the texts.
He also says:
"But if I do,
though you will not believe me, believe the works: that you may know and believe that the Father is in me, and I in the Father." John 10:38 (my emphasis). You have clearly stated you don't believe 'the works'. You refute the miracles.
They – we – don't know, because we are not one in the Father as He is. We are
potentially one, but not
actually one. If we were, then He'd be wrong in what He's saying.
Furthermore:
He never says 'you and the Father are one.' rather He's affirming that He is, and that we are not.
Read
all the text, not just bits of it. You're only getting half the story and jumping to the wrong conclusion.
This is most telling:
(Thomas and Philip are questioning His after the resurrection)
"And I will ask the Father, and he shall give you another Paraclete, that he may abide with you for ever. The spirit of truth, whom the world cannot receive, because it seeth him not, nor knoweth him: but you shall know him; because he shall abide with you, and shall be in you. I will not leave you orphans, I will come to you. Yet a little while: and the world seeth me no more. But you see me: because I live, and you shall live. In that day you shall know, that I am in my Father, and you in me, and I in you."
John 14:16-20 – but please read the whole discourse.
Points to consider:
The world – that's us – does not know the Paraclete, the Holy Spirit. Jesus will send Him to the disciples.
(This hadn't happened yet, it occured at Pentecost.)
In the Mystery of Baptism we receive and are in (potentially) the Holy Spirit.
(t's not a given, we have to embrace it.)
By accepting the Mystery of the Eucharist we receive and are in the Son.
(Ditto.)
It's
only then, in the Holy Spirit, that we can say 'Abba' – 'Dad' – to say that is a Trinitarian act, it involves you, the Holy Spirit, the Son, and the Father.
Your in Saul's boat. He didn't believe Jesus was God either. Then something happened.
The Father is in the Son and in the Holy Spirit.
He is not in us as a given. We have to accept and embrace the Holy Spirit to know the Son, and accept and embrace the Son to know the Father.
This is not to deny the Grace of god to humanity as a whole. The difference is, they are 'anonymous Christians', whereas those who take on board His message can and will come to know – gnosis – the Holy Trinity as Three and as One and as God.
