Ginger I've used these as part of an Advent Taize, but they could be used anytime. First line is the prayer, second line is the response:
Come, Lord Jesus, break the chains of warfare and terrorism ?
Come as a light into the world
Come, Lord Jesus, break the chains of poverty and hunger ?
Come as a light into the world
Come, Lord Jesus, break the chains of homelessness ?
Come as a light into the world
Come, Lord Jesus, break the chains of oppression, persecution and denial of human rights ?
Come as a light into the world
Come, Lord Jesus, break the chains of inequality and unfair practices in our society ?
Come as a light into the world
Come, Lord Jesus, break the chains of anxiety and unhappiness ?
Come as a light into the world
Come, Lord Jesus, break the chains of apathy and indifference ?
Come as a light into the world
Come, Lord Jesus, break the chains of sickness, disease and death ?
Come as a light into the world
Alternatively you could use visual intercessions, where you just project pictures onto a screen and people meditate on the pictures, and you play music in the background. I can email you an example of those is you like...?
