Sin is a meme and not a good one

Pope Francis declares evolution and Big Bang theory are real and God isn't 'a magician with a magic wand' 

It's great the Church is coming around to accept the physics-based explanation of the Universe and origins.  But this approval or validation is not necessary.  Science doesn't care what the Church thinks about it.  The Church is a participant in science as demonstrated by their astronomical interests.  But Science ignores praise over the cold criticism of peer review.

Of greater importance is the acceptance of evolution.  Now that's an admission that will have far reaching consequences for the Christians that still hold onto the belief the Earth is 6000 years old.

On the other hand, it's not cool that he's decided that God isn't a magician and that there was a genesis of the Universe from the Big Bang.  He's offering an alternate theory as to the universe's creation.  Unfortunately, he is not authoring a paper and submitting it for review by scientists.  If he did that, he would have to submit all the proof of his postulates along with his theory.  That would be the true test for the existence of God.

The arrogance of the Church, as cool as Pope Frank may be, is that they decree their views and do not submit to examination.
