I see that his holiness and chief spider catcher of the cult of misery, Pope Benedict, wants to introduce a whole new batch of mortal sins, such as the sin of engaging in morally debatable genetic research. It's reported in The Times, together with some spirited discussion.
It's nice to know that the misery cult is hard at work for our souls - always dreaming up new sins for us to worry about and nifty new rationalisations for attacking our freedoms.
Personally, I think it's reprehensible to bring up innocent children in a cult of misery, or to teach them to accord moral authority to popes, priests, pastors, preachers, presbyters, and other such pretenders. It's not exactly a sin, though, since "sin" implies a deity to sin against, and I haven't noticed any deities around these parts of late.
