Martin was an extraordinary, tenacious, and courageous ecumenist, who devoted his mind, heart and strength to the unity of the whole church, and always for the sake of justice and peace in the world,” said Rev. Dr Susan Durber, moderator of the WCC Faith and Order Commission. He lived his own Christian life as well his working life in ecumenical contexts and burned with holy zeal for the unity of Christs people.”
