In the current terrible situation in Europe, these words from Benedict XVI during an Angelus in July 2009 are very appropriate:
"It is written in Genesis that the blood of Abel killed by his brother Cain calls to God from the earth. Unfortunately, today as yesterday, this cry has not ceased as human blood continues to flow because of violence, injustice and hatred. When will men learn that life is sacred and belongs only to God?" "The Blood of Christ is the pledge of God’s faithful love for humankind. By gazing at the wounds of the crucified Christ each man, even in conditions of abject moral poverty, can say: ‘God has not abandoned me, He loves me, He gave his life for me’, and thus rediscover hope".
