"Seventy-five years after the end of the Second World War, the memory of the victims of this massacre imposes on us a homage of respect and a duty to prevent conflicts by all means," he said.
"Believing in peace" implies "an increased rational commitment to transform the world according to the imperative of unconditional respect for the dignity of the human person, unfortunately undermined by ideological colonization hostile to the sanctity of human life," he said.
"In this difficult context, believing in peace also means relying on the efficiency of prayer for peace, since the Spirit of God directs human history towards its transcendent accomplishment with the imperfect but voluntary support of human freedoms."
Cardinal Ouellet lamented the terrible cost of the World Wars: "The bitter feeling of the monstrous cost of these conflicts remains a heavy legacy that does not erase what has been achieved in the positive and generous achievements in European reconstruction. That is why remembering the end of the last great conflict is a duty of respect for the too many victims of these tragedies and a permanent requirement for reflection and commitment to prevent such disasters from happening again in the future."
"There is a constant need for reflection and commitment to prevent such tragedies," he stated. "But man does not seem to have learned much from his past sufferings: we are experiencing a globalization of oblivion and indifference to the victims of today, and conflicts have not ceased to increase and fragment on all continents."
Archbishop Timothy Broglio of the US Military Services marked the anniversary saying: "On my last visit to Normandy in 2015 I was struck by the number of French men and women who came up to me and said: 'We will never forget what your countrymen did here.' Indeed it is important to remember and give thanks for the sacrifices made on the beaches of Normandy and elsewhere in Europe and in the Pacific Theater."
