One of Britain’s most prominent and internationally acknowledged peace campaigners visits East Lothian this weekend.

Former priest Bruce Kent, vice-president of Pax Christi - the international Catholic movement for peace - will speak about its work and introduce Pax Christi Scotland at an event at Our Lady of Loretto Church, Musselburgh tomorrow (Saturday).

Vice-president of Campaign for Nuclear Disarmament, he was the organisation's chairman 1977-79 and 1987-90, and general secretary, 1979-85. During these years, he led CND through its most crucial phase – the struggle against cruise missiles – and steered it through tumultuous times. He continues to champion a range of Christian and humanitarian causes.

The event will get underway with a Mass for Peace and Reconciliation at 10am, followed by Exposition and Rosary.

From 10.30am there will be coffee and registration before Mr Kent speaks about Pax Christi at 11am. This will be followed by a soup and salad lunch. Closing prayers will take place at 1.30pm.

There is no charge but a donation towards the lunch would be appreciated with any surplus after meeting costs going to the Scottish Catholic International Aid Fund (SCIAF).

The work of Pax Christi - the Peace of Christ - is based on the gospel and inspired by faith. Its vision is of a world where people can live in peace and without fear of violence in any form. It is rooted in Catholic christianity but is open to all who share its values and work.

The movement supports teachers, chaplains and youth workers in promoting a culture of peace in schools and amongst young people. It develops solidarity between people who are working non-violently for justice and peace. This is done through joint actions for peace in Israel-Palestine, events to encourage international efforts to abolish nuclear weapons and by celebrating the life and witness of peacemakers.

Pax Christi promotes an understanding of sustainable security where human needs are met and the environment is protected, rather than seeking security through weapons and warfare. It campaigns against military spending, the arms trade and nuclear weapons.

Mr Kent will also speak at St Martin's RC Church, Tranent, after 10am Mass on Sunday, and St Gabriel's RC Church Hall, Prestonpans, after 11.30am Mass the same day.
