From the article; "Cremation, in and of itself, does not constitute a denial of belief in the immortality of the soul and the resurrection of the body, the instruction says. Nor does it "prevent God, in his omnipotence, from raising up the deceased body to new life."

I'm pretty sure God can accomplish the same thing no matter the disposition of  the body --- even from scattered ashes or from an urn on a mantle.

The article's inference that belief in, or an actual resurrection of, the body and eternal recombination of body and soul is tied to the means of burial and memorial seems far fetched. My money is on the fact that God is not swayed by the arguments posed in the article. 

I am not swayed, either. I'm more inclined to be believe that this is a push for continued use of church controlled cemeteries, which I think are money makers for dioceses.
