Is John 10:30- I and the Father are one.- really a decent trinitarian proof text?
I think the context means that the Father and the Son are in accord/special relationship with each other, that they share the same goal and purpose. Often the response of the Jews to stone Jesus because he made himself God, is used but Jesus does not defend such a notion but goes back to the OT 's use of 'gods' and finally clearly says that he himself is the Son of God.
Also, look at John 17 where the very same language is used - the son and Father as one-, it is paralleled with the desire of Christ for the disciples to be one in the same way, or just as, the Father and the Son are one. this is in verses 11 and 21,22 of John 17.
Yes. Not a good proof text, for sure. Its like when I tell my children that their mom and I are united and of one mind when the to comes to discipline and making important decisions. We can't be turned against each other or devided.
"All those evil doctrines about god that work misery and madness have their origin in the brains of the wise and prudent, not in the hearts of children." -George Macdonald
Agreed that the phrase "I and the Father are one" on its own doesn't equate to Jesus self-identifying as deity. Jesus saying he is the "Good Shepherd" or the "sheep gate" is more of a claim to be "in very nature God" than him saying that he is one with the Father. It was probably more for those reasons they wanted to stone Him.
You’ve got your methods
I’m done with trying to guess all your moves
I’m going where you want me to go
I’ve got nothing left to lose
Now I don’t wanna suffer
But that’s in fact the nature of the beast
If you want to get to higher ground
You got to get there on your knees
