A Concord Pastor and Rocco both have good posts on World AIDS Day with Church-related resources. Rocco's post includes this 2007 quote from Pope Benedict XVI:
"Next 1 December again marks World AIDS Day. I'm spiritually close to the many who suffer from this terrible illness as well as their families, particularly those stricken by the loss of a loved one. Assuring all of my prayers, I likewise wish to exhort all people of good will to multiply their efforts to stop the spread of the HIV virus, to combat the harm which affects so many, and to take on themselves the care of the sick, especially those who are young."
