Also, I apologize if the first sentence in my last comment sounded condescending. Regarding theology and what you referred to in bringing up Genesis, I would recommend reading some Catholic apologetics on that, as that is not my area of expertise. I simply offer my opinion regarding how Christians ought to look at ecumenical dialogue. Take care.
We're way past having to do that, pal. I've been there and know from personal experience.
If Genesis 1-11 is "unscientific," then so are the numerous "miracles" that have been violating the laws of nature since that time. Plus there's the little matter of calling G-d a liar when He says something happened and the "one true Church" says it didn't.
