Pictures of Prayer
The Exhibition Hall has stalls focusing on human rights, the work of the church in the world, and its educational and social work. But visitors also notice one stall lined with vividly-coloured icons which would not look out of place in an Orthodox church or home - though these are created by four Brazilian Roman Catholics.
For Cica Anawate, Clarice Jaeger, Ismael Alves and Niura Arnt Fernandez, painting is a form of prayer. "We paint praying," says Cica, explaining that they listen to Gregorian chants as they work.
Each of the paintings is created with a particular person or situation in mind. "It transmits a great peace to us," she says. For those who take one of their paintings home, their work is a blessing, and a way in which God continues to speak to them.
