Nairobi — Christians have been urged to participate fully in the fight against corruption and injustices in the society.

"This should be part and parcel of the Church teaching and the Christians should embrace it in their daily life", said Presbyterian Church of East Africa (PCEA) Church minister, Edward Buri.

The Church minister, who is the PCEA Youth Director at Saint Andrews PCEA Church, Nairobi was delivering a sermon at the Catholic Saint Paul's University Chaplaincy, Nairobi on Saturday, January 19 during the Service of prayer to mark the Week of Christian Unity for 2013.

The week of Christian Unity, opened on January 18 and will close on January 25.

This year's theme of the Week is: What Does God Require of Us? taken from the Book of Micah 6: 6-8.

In Kenya, the Week is being animated by the Nairobi Ecumenical Group NEG), which has carried the similar exercise in the past.

Pastor Buri reminded the congregation, which included clerics and Christians from various denominations the need for the Church to participate in leadership matters.

In the country's forthcoming general elections, the Church through its leaders and followers should ensure that it has participated fully in this political exercise, he emphasized.

"God has mandated us to undertake this mission and therefore we must feel obliged to do this," added Pastor Buri.

On behalf of the participating churches in the ecumenical Service, Father Patrick Kanja, Father-in-Charge of Saint Paul's University Chaplaincy praised the ecumenical seed they have managed to plant by holding the annual Week of Christian Unity jointly.

Choirs from Saint Paul's University Chaplaincy and PCEA Saint Andrews formed part of the Service. Also a deaf choir from St Andrews PCEA Church also sang to the congregation, through its sign language instructors.

The ecumenical congregation later on congregated for a cup of tea and biscuits, hosted by the NEG.
