Transubstantiation in modern science: How can substance change without accidents

[Walty]

Is it proper to say that God can do any conceivable or possible thing?  Someone once said that asking if God can make a four sided triangle is like asking if God can al;sdifjasdfklajsdlfij.  No such thing. 

Yes, that's the correct way of looking at it.  And it's not about "thinking God" as opposed to "receiving Him" though that's fine if Allan sees it that way because I don't think he's fallen into any of the issues raised by not doing so.  But it is important that theologians make this distinction as it's fundamental to our entire conception of God and His nature.  As I mentioned before, without it the very foundations of truth become arbitrary, as they are in Islam, and God is allowed to contradict Himself, making the truth less real.
