Let's not forget the "Fathers" were wrong about many things. Luther thought Corpernicus and Galileo were wrong about helicentrism. Why do people think the fathers, who knew virtually nothing about science (or the biblical languages) compared to us, have some kind of special insight to science? That doesn't make sense. Many people just go through history picking people who support their view. That doesn't prove their view, it only shows someone else had the same view. It's like the Darwin Fundies who make a list of people who support Darwinism then use that as proof for Darwinsim.
Most people wouldn't consider those two characters to be fathers. When I mean fathers, I mean bishops, priests, or monks writing between approximately A.D. 50 and 600.

They don't have special insight into science, but they do have special insight into theology and Biblical exegesis because they lived closer to apostolic times. And yes, some Fathers did have special insight into the Biblical languages. Many of the early Fathers, like Origin, lived in societies wherein the Biblical languages were still in everyday usage. Others had access to ancient texts in these languages that have since been lost.

Well, that's not how patristic research is typically done. What you should do is study the Fathers as a group and make note of issues upon which there is broad agreement. When you see that, it is significant.
