Does this mean you believe the Vatican errs when it supports evolution?
It means Gore is wrong - but if the shoe fits...
Actually, unless the Pope speaks infallibly: "the charism the Pope "enjoys in virtue of his office, when, as the supreme shepherd and teacher of all the faithful, who confirms his brethren in their faith (Luke 22:32), he proclaims by a definitive act some doctrine of faith or morals." a Catholic need not agree with a pronouncement from the Vatican.
It supports science--you can't say it supports evolution any more than you can say it opposes it. God has always been the author--what language He writes is up to us to decipher.
