As we remember those events and the innocent who died, let us also remember those who served in their vocations and lost their lives in trying to save others.  Then let us pray –

Heavenly Father, God of all concord, it is Your gracious will that Your children on earth live together in harmony and peace. Defeat the plans of all those who would stir up violence and strife, destroy the weapons of those who delight in war and bloodshed, and, according to Your will, end all conflicts in the world. Teach us to examine our hearts that we may recognize our own inclination toward envy, malice, hatred, and enmity. Help us, by Your Word and Spirit, to search our hearts and to root out the evil that would lead to strife and discord, so that in our lives we may be at peace with all people. Fill us with zeal for the work of Your Church and the proclamation of the Gospel of Jesus Christ, which alone can bring that peace which is beyond all understanding; through Jesus Christ, our Lord. Amen.
