Wait a minute. Who said anything about a birth certificate? Your religion isn't identified on your birth certificate.
Unless of course he is the son of Satan. The father of lies begets liars. Obama's words bear witness to his character (hence religion - all lies all the time), providing ample evidence for his origin of birth.

At least he wouldn't be a British subject...so there's that.
