It's odd to see this sort of philosophy/theology posted on here, but since the subject was broached, from the article:
> Virtually all the world’s major religions teach that diligent work in the service of others is our highest nature and thus lies at the center of a happy life.
Actually, Ecclesiastes (great read for all philosophy geeks) is a long discourse of happiness, the point of life, etc. Its final conclusion was:
> Fear God and keep his commandments, for this is the whole duty of man.
The core of Judeo-Christian theology is the supremacy of God and trust that following His instructions is the best way to live the best possible life. Of course there is a lot of teaching about how to care for others, and there's a lot of teaching against selfishness, but that is the result of following a good God, not the point in itself.
Ecclesiastes actually brings up charity as wise, but falls far short of saying it's the point of life. It points out that there's limits to human knowledge. In my wording, help people, because that could be you tomorrow, but the person you save from a fire today could drown tomorrow. You'd need to be able to see the future to utterly help someone, and only God has that kind of foresight. So if you trust that God exists and is good, you should obey His teachings.
> Indeed, what unites the two of us in friendship and collaboration is not shared politics or the same religion. It is something simpler: a shared belief in compassion, in human dignity, in the intrinsic usefulness of every person to contribute positively for a better and more meaningful world.
I'm eager to collaborate productively with everyone. But if you're interested in being my friend, you need to understand where I come from. I value human life because mankind was made in the image of God (imagao dei). My eagerness to give human compassion, dignity, and usefulness another shot grows out of my trust in God and his teachings that say to do just that. But I do that in spite of the track record of humanity, not because I have faith in what humans will do in the future. Who knows the future?
There's a bit of an "all religions are the same" meme out there, and it's important to correct it, especially when respectable people repeat it.
