well, I am not Fundamentalist, doubt that I am average, but could fall under the Evangelical label…I expect that the typical Evangelical would not think that “trogos” in any way necessitates a non-figurative understanding…we are absolutely unaware of any linguistic rule (in either greek or english) that prohibits the use of “trogos” in a figurative statement…
For example, I might tell you that “I’d eat you alive” if you try to make the argument that the use of “trogos” in John 6 supports the doctrine of a real bodily presence. I might also tell you that “I’d chew you up and spit you out” if you try to argue that the use of “trogos” in John 6 supports the doctrine of a real bodily presence. You should note that my use of more graphic words such as “chew” and “spit” does not mean that the second claim should be understood literally.
What has always puzzled me about the question you present is the obvious fact that no one who believes in a real bodily presence actually has ever “trogos-ed” any flesh at a Eucharist…the participant’s teeth never actually touch the flesh of Jesus…the most that could be claimed is that the “accidents” of the participant’s teeth are involved in a chewing action that also involves the “accidents” of the bread. Chewing flesh involves grinding it into smaller bits…at your Eucharist do you grind Christ’s flesh into ever smaller bits?..I thought Christ’s body was supposed to be present (in its entirety)in each and every bit…I have no idea why you would think the use of “trogos” presents any sort of problem for the average Evangelical/Fundamentalist Protestant.
