The resurrection of Jesus is proof of his divine ability.
...or Jesus died like everybody else.
I normally try not to post in religion threads, as my views are rather cynical, but here goes nothing.
Most religions are a paradox. Here's why:
1) God made man with freedom of choice
2) God is all knowing
It is physically impossible for god to make man with freedom of choice, as he is all knowing and already knows what those choices are going to be. In essence, all your decisions are predestined, based upon a decision made by god, and as such, you have no freedom of choice.
Back to your original question. Is Jesus the son of the Christian/Catholic god?
No.
The concept of him being the son of god is yet another paradox. Jesus walked this Earth because humanity was "doing it wrong". They didn't understand worshipping god, they were committing evil, yadda yadda. But god is all knowing! When he made man, didn't he realize that man would eventually "do it wrong"? And if he did, why didn't he make man differently?! If Jesus is the son of god, then god on purpose made man flawed, knowing all the while thousands of years later he'd fix it.
WHY!? Why not just make Utopia? And you can't say he did with the Garden of Edin, as he's all knowing and knew what Eve was going to do. The only logical conclusion is that god made us flawed because he felt like it. And, if you pay attention to the bible, he caused several massacres, knowing they were going to happen ahead of time, but didn't bother to prevent them. Sounds merciful to me!
If god truly made man, then he either isn't all-knowing and infallible, or Jesus isn't his son.
...and now back to avoiding religious threads.
