According to the Christians at Catholic Peace Fellowship it is. Long before people got shot in their bedrooms, at the mall, in the church, or at the bus stop the Catholic church taught the fallacy of redemptive violence. "I am a soldier of Christ and it is not permissible for me to fight" St. Martin of Tours, 315-397. "Lord, make me an instrument of your peace" St. Francis of Assisi. "The God of Peace is never glorified by human violence" Thomas Merton.
More recently, Catholic leaders have reiterated this emphases."On my knees I beg you to turn away from the paths of violence and to return to the ways of peace" Pope John Paul II. "God and our love are the condition for the unity of Christians. They are the condition for peace in the world" Pope Benedict XVI.
And most recently, on February 18, 2007, Pope Benedict XVI said [click the pic to read the entirety of his talk] before several thousand people gathered in St. Peter's Square of Vatican City. “Dear Brothers and Sisters! This Sunday's Gospel has one of the most typical, yet most difficult, teachings of Jesus: Love your enemies (Luke 6:27). It is taken from the Gospel of Luke, but it is also found in Matthew's Gospel (5:44). But what is the meaning of his teaching?
This page of the Gospel does not consist in surrendering to evil—as claims a false interpretation of "turn the other cheek" (Luke 6:29)—but in responding to evil with good. (Romans 12:17-21) thus breaking the chain of injustice. It is thus understood that nonviolence, for Christians, is not mere tactical behavior but a person's way of being, the attitude of one who is convinced of God's love and power, who is not afraid to confront evil with the weapons of love and truth alone. Herein lies the novelty of the Gospel, which changes the world without making noise. Herein lies the heroism of the "little ones," who believe in the love of God and spread it even at the cost of life."
What do you think? Would as many children be getting shot at bus stops if all the Catholics in the US followed and encouraged others to follow the Pope's advice?
