There are many international seminars held in Medjugorje throughout the year, including the regular seminars of fasting and prayer. Some of these seminars have a long tradition and some were initiated only in recent years. They are for priests, lay people, leaders of peace centres, married couples and doctors and medical staff. The meeting of the Organisers of Pilgrimages, Leaders of Peace Centres, Prayer and Charity Groups was held at the beginning of March. The Third International Spiritual Seminar for Doctors and Medical Staff will be held from May 13-16, 2015, and the theme of the seminar will be "Peace be with you" (Jn 20,21). The programme for the seminar will consist of prayer, lectures, testimonies and participation in the evening prayer programme, all conducted by the seminar leader, Fr. Ljubo Kurtovic.
