One thing I found interesting in a quote from one of the Church Fathers cited by Dr. Sungenis was where the Father in question said that there were many theories about the shape of the earth and that just as soon as one became widely accepted, a new one would pop up, and the old one would be discredited. He was using that to illustrate the unreliability of scientists in general. Outside the question of FE proper, this also dispels the notion that the "entire world" believed in NASA's ball-floating-through-space earth model since 500 B.C.
