South Sudan: Comboni missionary appointed Bishop of Rumbek

Pope Francis has appointed Fr. Christian Carlassare, Comboni missionary, as Bishop of Rumbek, South Sudan.

In his first message to the Christian communities of the diocese the new bishop said: “I am grateful to Pope Francis and the Church for the love and trust that have shown by calling me to the episcopal ministry and appointing me to be the Bishop of Rumbek.”

He continues: “My thoughts go out to all the people of the diocese and their desire to encounter Christ in the Church. My obligation goes to all priests that are serving in the diocese, in particular Fr. John Mathiang for his commitment to lead the diocese in the past years as diocesan coordinator. I also recall the person of the late Bishop Caesar Mazzolari who gave his life to the people of Rumbek with the spirit of a good shepherd.”

“My appreciation goes to all the religious institutes and communities of men and women that enrich the diocese with their charisms, among them I show special gratitude to my confreres, the Comboni Missionaries and sisters. I am also indebted with the Diocese of Malakal for the spirit of communion, support and kindness: May God reward you,” he said.

The new bishop recognized the commitment of laity serving in the Rumbek diocese. He pointed out: “I also acknowledge the commitment of many lay people, whether native from Rumbek or from other places and countries, those who work in the offices and institutions of the diocese, and committed Christians such as catechists, members of church councils, associations, men and women, youth and elders who form and build up this family of God.”

He concluded: “I want to express my readiness to join the diocese of Rumbek entering in the journey that you have been doing so far and offering my humble self. But, at this moment, what I ask you more is for your prayer, with the trust that our Lord who started this good work will assist me with his grace and bring it to completion.”
