For me, one reason it was important to mark this fourth anniversary was that I was unable to do anything more than march at the time of the invasion in 2003, due to personal circumstances. I felt bad about that then, and given how events in Iraq have developed over the last four years, it seems to be even more of a kind of 'sin of omission' now. And I wanted to remedy that in some small way. I think we - I - wanted to remember the dead, the innocent victims. The season of Lent seemed to be a proper time to be planting crosses - crosses of repentence during this season of liturgical journeying towards the Cross of Jesus. It seemed  a proper time too, to make the link in my own life between the so-many crosses that are planted 'in our name' - and at the behest of so-called Christians George W Bush and Tony Blair too - in Iraqi soil - and the Cross of Jesus, the 'loving-kindness of the heart of our God' (Benedictus, Luke ch.1) - by planting crosses in the soil of Parliament Square. And too, Lent is about allowing our hearts which have become hardened to be made flesh again, allowing ourselves to be wounded by the sufferings of others. And I often feel that I don't allow myself to be touched to deeply by what is happening in Iraq, I don't allow myself to be wounded with anger or grief by the pain and the violence and the despair and the calousness. And this kind of witness I find gives me the opportunity to be converted, to open my heart and mind more fully to this reality, perhaps because it contains in it also the grace of God, which brings a hope that can never be defeated. Whereas otherwise such heart-knowldge would bring only despair and paralysis, blackness and bitterness, which do no one any good, including Iraqis. That is why for me it is important to pray as well as act on these occasions, to open up a channel of God's love in the world.
