Essentially the same or Fundamentally different?

Expressing a theological truth or merely making a political statement?

My understanding is that the three Abrahamic religions - Judaism, Christianity and Islam - share the same One God, although obviously they differ in their understanding of that God. They also share the same foundational scripture - they are People of the Book - although again obviously they have diverged from that original foundation. So yes, she was expressing a theological truth, but presumably she was also making a political statement.

That's my general feeling. However, her employers at Wheaton College -- a school well known for its programs in Protestant Theology etc -- seem to regard her "all one" talk as an act of apostasy.

My impression is that evangelical protestant theology in the USA is often out of step with worldwide theologies. I come from the Catholic stable, but I suspect that many Lutherans, Anglicans, Orthodox and others would also accept the view that the Abrahamic religions share the same God.

Is Jesus deity?

The Holy Spirit a distinct deity from the Father?

Christianity's focus is redemption from sin.

Is that focus shared by Judaism and Islam? Is that the central theme of those faiths, as it is with Christianity?

I ask this because Christians might assume that salvation holds the hope of all religions, and I think Judaism is concerned less about salvation and more about living in this life. That is my impression anyway.

I do not know much about Islam.
