Thomas J. Reese commented that "using Aristotelian concepts to explain Catholic mysteries in the 21st century is a fool's errand", while Timothy O'Malley remarked that "it is possible to teach the doctrine of transubstantiation without using the words 'substance' and 'accidents'. If the word 'substance' scares people off, you can say, 'what it really is', and that is what substance is. What it really is, what it absolutely is at its heart is Christ's body and blood".
