I missed that argument. In my mind "confect" is potentially a very useful word in discussions about the Eucharist among Catholics because it can be construed, fairly, as neutral to the differences of opinion among progressives and conservatives. The word is seldom used in modern English, and when it is used, it tends to mean making something by combining ingredients. But the etymology is not that precise--it comes from the Latin "facere" (to make, create in the most generic sense possible) with the prefix "con", in this case an intensifier, stressing the act of making/creating. I would guess that the sense of making from ingredients comes from the "con" understood as the Latin "cum" = "with."

The point is one can read "transubstantiation" in rigid Aristotelian metaphysics or read other philosophical sense into the Eucharistic action of the liturgy as confection.
