The World Council of Churches central committee, which wrapped up its Geneva meeting on Monday, has approved the appointment of a search committee to appoint the next general secretary. The election of a new general secretary is expected to take place at the next central committee meeting in September 2009.
Kobia said on Monday that personal reasons were behind his decision not to seek a second term. The WCC central committee was to consider an extension to his current term, which ends 31 December 2008.
"The central committee received this news with regret but accepts the decision of the general secretary. We want to respect his decision and privacy," WCC Central Committee moderator Rev Dr Walter Altmann said Monday night.
"We want to express the deep gratitude of the World Council of Churches for the dedicated services he has given to the council since becoming general secretary in January 2004."
Kobia, a Kenyan Methodist, was the first African to take up the post of General Secretary of the WCC when he was elected in August 2003. He was formerly the General Secretary of the National Council of Churches in Kenya.
In addition to being general secretary, Kobia had previously served as executive director of the WCC "Justice, Peace and Creation" unit and as director of the cluster on "Issues and Themes".
