Check out Pope Benedict's first Encyclical
Pope Benedict XVI has written his first Encyclical entitled "Deus caritas est" (God is love). It is dated December 25th and it talks about the question of Christian love. I have just scanned the summary so far, but am looking forward to reading the complete text.
This really grabbed me from the summary...
"By participating in the Eucharist, we too become involved in the dynamics of His act of giving. We unite ourselves to Him, and at the same time unite ourselves with everyone else to whom He gives Himself."
WOW! That's powerful!
