No where in that passage does it say God sent the bears. Besides the kids were mocking a prophet of God. The old testament also uses alot of hyperbole or exaggeration, so no telling if this really happened. The Catholic church doesn't believe everything in the Bible is to be taken literally. The point in the story is probably that those who represent God and His word should be given a level of respect. You're welcome to discuss these types of bible passages or other teachings of the Catholic church in a respectful manner in this stream.
