Drawing from Sunday’s Gospel reading, Pope Benedict XVI explained the "logic of Christianity," during his weekly Angelus address at Castelgandolfo.  The Holy Father told the hundreds of gathered pilgrims that “the logic of love..the logic of Christianity” is the giving of self.

The Holy Father quoted today's Gospel reading in which Jesus announces to His disciples, for the second time, His passion, death and resurrection. The evangelist Mark, said the Pope, "highlights the strong contrast between Jesus' mentality and that of the twelve Apostles, who not only do not understand the Master's words and refuse the idea that He may die, but discuss among themselves which of them is 'the greatest.'”
 
"Jesus patiently explains His logic to them," the Holy Father added, "the logic of love that is service even unto the giving of self. ... This is the logic of Christianity, which responds to the truth of man created in God' image, and at the same time contrasts man's egoism, a consequence of original sin. All human beings are attracted by love - which in the final analysis is God Himself - but often mistake the concrete ways to express that love. And thus from a tendency that in its origins is positive, though polluted by sin, evil intentions and actions can arise."
 
Pope Benedict went on to recall the words of the Letter of James: "For where jealousy and selfish ambition exist, there will be disorder and every vile practice. But the wisdom from above is first pure, then peaceable, gentle, open to reason, full of mercy. ... And the harvest of righteousness is sown in peace by those who make peace."
 
The Holy Father concluded his remarks calling to mind the ultimate self-sacrifice made by many Christians: "these words make us think of the witness of so many Christians who ... dedicate their lives to the service of others for the sake of the Lord Jesus, working as servants of love and ... 'artisans' of peace. Sometimes, he said, some of them are asked for the supreme witness of blood, calling to mind the murder of Italian religious sister, Leonella Sgorbati.  Sr. Leonella, he said, offered “the most authentic Christian witness” dying in love as she spoke the word, “forgive” with her last breath.
