As a witness for Peace, our role was to witness in two senses of the word: we SAW, and by our presence we offered affirmation by word or example of a solidarity based on love and faith and the Good News. The word that is much used is "accompaniment." Our contribution was less in our doing than our being-with.
I am content to follow to its source
Every event in action or in thought;
Measure the lot; forgive myself the lot.
When such as I cast out remorse
So great a sweetness flows into the breast.
We must laugh and we must sing,
We are blest by everything,
Everything we look upon is blest.
