One can't be a heretic against that which you don't profess, so no you aren't a heretic. However you seem to reject the collective authority of scientists who are authorities by virtue of their demonstrated expertise.
The inerrancy of scripture isn't at issue just as objective truth isn't at issue. The issue is by what method is truth revealed and who decides that it has been revealed. I say that the collective judgment of appropriate magisteriums is the better method to decide what is true or probably true.
They aren't looking at the whole picture, but only at a slice of it, and they aren't even objective about that. They aren't looking for truth. They are seeking to back up views they already have.
If you are a Catholic, to get a hold of Touchstone or First Things magazines and get some theological perspective on your scientific, and therefore, severely limited worldview.
Thanks for the discussion.
