Catholic Educator's Resource Center...
has some good articles up....
First off, there's two on the problems with 'bioethics'. There is also one on the Dutch endorsement of mercy killing for tots.

Finally, my personal favorite:
The Media and Church Teaching.

Ellen Goodman thinks the Vatican needs a hearing aid because the pope does not listen to her, not that she needs to listen. If consecrated virginity, or the required use of wheaten bread, were beliefs of a Native American tribe, the enlightened class would be very severe in cautioning us to respect precisely what we do not understand and to learn from it....
