It's like true in the unassailable scientific sense.
It's true to the extent that the facts of reality support it, like any other scientific theory.
And evolution theory just so happens to be extraordinarily well supported.
You believe the theory of evolution, don't you? If the Pope says evolution is true, one must come to terms that he also says the eternal virginity of Mary is true beyond question.
I
accept evolution theory as the best supported explanation of the facts, because it is the best supported. I couldn't care less what the pope has to say about it.
Although the theory of evolution is not, I suppose many might think, is without question, yet the Pope believes it.
No scientific theory is without question.
On what grounds, other then personal incredulity, would you question the theory though?
So on a level of truth, it's as good as the dogma of the perpetual virginity of Mary.
No.
On the level of truth, it's as good as any other well-supported theory of science.
It could be said though, that in all of science, evolution is among the best supported, if not THE best supported.
We know more about evolution then we do about gravity, for example.
If you don't accept that they are parallel doctrines, even if you don't believe the theory of evolution is a doctrine or dogma, that's ok, it's up to you. The End.
Evolution is a theory.
Theories aren't doctrines nor dogma.
