I found this nice little video with a good summary of the events that took place.
Some other good resources that I use often are:
www.catholic.com
(Catholic Answers is one of our favorite shows on the radio, and now they have a youtube channel)
www.newadvent.org
http://www.vatican.va/phome_en.htm
www.catholicunderground.com
And the good ole Catechism, that one's chock full of answers!
Now, going eat a nice Lenten meal with the family!
Buona notte,
Nick
