Of all that can be said about the tragic events of October 22, 2014 at the War Memorial and Parliament Hill, one thing we can agree on: something changed. In the aftermath of the shootings, we are still figuring out exactly what.

The day started for me with great anticipation that evening of the ‘battle of Ontario’ between the Senators and Maple Leafs at the Canadian Tire Centre. The day certainly didn’t end that way.

As I drove past the quieted Canadian Tire Centre with its vast, empty parking lots on my home late that tragic day, I marvelled how a single act of cowardly violence could alter the psyche of a city: The anticipation of a sell-out, jam-packed arena was suddenly silenced. Instead, I along with the rest of the city was eager to get home to be with family and loved ones after a day of anxious and often chaotic lock-downs in schools and downtown buildings.

Images of armed officers and special police units swarming familiar and beloved symbols of national remembrance, barricaded Members of Parliament, horrific visions of a slumped body at the foot of the war memorial ricocheted in my mind. Sounds of gun shots from security personnel in the Hall of Honour in Centre Block echoed in my head.

And then, words from the Prime Minster and other party leaders assuring Canadians that this attack was aimed at undermining our values. It seems times of collective crisis, such as this one, burn through all our usual distractions and reveals what is truly important to us. Indeed, now is the time to affirm, and attempt to clarify, what is the nature of our identity and community.

Earlier in the day I went to the Ottawa Civic Hospital where the victims of the violence were taken. The place was streaming with extra security personnel at the entrances and in front of the emergency department. What struck me was the way in which the medical staff went about their usual business of caring for the patients in the hospital. Obviously aware of the ongoing, ‘dynamic’ operation downtown and the possibility of many more injured to arrive any time, they nevertheless kept to their scheduled procedures with smiles and loving attentiveness to others. Their jobs, however routine, became infused and enlivened with caring compassion, in the moment.

On the eve of the shootings, Bishop Munib Younan — president of the Lutheran World Federation and Bishop of the Evangelical Lutheran Church in Jordan and the Holy Lands — spoke in downtown Ottawa to a diverse group of Lutheran leaders and laity about peace. He described an image often portrayed in the media of young people in his part of the world throwing stones at their enemies. Bishop Younan prays for a day when those stones could be used to build bridges of peace.

How appropriate. He was, after all, speaking to Canadians whose international reputation is one of peace-keeping and building, respecting the humanity dignity of all people.

In all the media reporting on Wednesday, I heard an American security official comment on what he saw to be a typical Canadian response: He observed how RCMP officers and Ottawa Police communicated with the public on the streets of downtown Ottawa in the hours following the shooting; they would often say ‘please’ move to the other side of the street. Politeness and consideration continued to be hallmarks of our public interaction, even in the midst of a crisis.

Some say now we should no longer be so ‘laid back’ as Canadians. We should be tougher, more aggressive. On Reformation Sunday today we sing with pride Martin Luther’s hymn, “A Mighty Fortress is our God”. Let us, dear friends, not become the fortress where we exclude others who are different from us. Let us, dear friends, not become a fortress where violence escalates and hatred is encouraged — which is precisely what the haters want. Now is the time to affirm what has always characterized us for the good.

But what is that, as Lutherans? Martin Luther affirmed that we are saved ‘by grace through faith’. What is a good metaphor for grace? Where does it come from, and where does it go?

Grace pools like water at the bottom of things. Water flows naturally into the lowest recesses of a land’s topography. Vast rivers seek their way downward towards the ocean. The grace of God is like water, whose primary direction is downward.

The cross of Christ is a symbol that God is discovered precisely where it hurts the most, where we feel the most vulnerable and shamed and exposed. This was central in the thinking and theology of Martin Luther — the Cross: God is found where we least expect it, when we least expect it. This is relevant especially to Canadians and Ottawans in particular, in light of what has just happened.

Could we respond not just with pronouncements of who we should be more like, but with a sober affirmation of who we are? Could we respond with a commitment to paying attention to what is reality for most of humanity around the globe, and not just for the rich and famous, privileged and elite? Could we respond by embracing again a faith that proclaims resurrection and new life through the ‘momentary’ suffering that comes to us all?

Martin Luther experienced the devil, at which he threw ink wells and much profanity, while alone in his study at Wartburg and during an immense personal struggle and angst. The Germans have a good word for it — ‘anfechtung’ — which describes an internal battle. The devil is not personified in any particular religious group or ethnic profile, but comes to us all in our own personal struggle with hatred, blaming, and self-righteousness. In Ephesians 6 Paul writes that our struggle is not against enemies of ‘blood and flesh’ but against ‘cosmic powers and spiritual forces’ to which we are, each and everyone of us, vulnerable. Therefore, in the words from 1 Peter 5:6-11 …

Humble yourselves therefore under the mighty hand of God, so that he may exalt you in due time. Cast all your anxiety on him, because he cares for you. Discipline yourselves, keep alert. Like a roaring lion your adversary the devil prowls around, looking for someone to devour. Resist him, steadfast in your faith, for you know that your brothers and sisters in all the world are undergoing the same kinds of suffering. And after you have suffered for a little while, the God of all grace, who has called you to his eternal glory in Christ, will himself restore, support, strengthen, and establish you. To him be the power forever and ever.

A mighty fortress IS our God. God will shelter us under the wings of God’s care and protection. No matter where we go — in the public spaces or by ourselves, alone. God will never leave us nor forsake us.
