The German Jesuit Stephan Lipke is to become an auxiliary bishop in Novosibirsk.
Pope Francis appointed the Essen-born priest as titular bishop of Arena, the Vatican announced on Thursday.
Lipke has been Secretary General of the Russian Bishops' Conference since 2020. He is also Director of the St Thomas Institute in Moscow and teaches medieval philosophy at Moscow's Patrice Lumumba University for Friendship among Peoples.
Originally ordained a priest in the Archdiocese of Cologne in 2002, Lipke entered the Jesuit novitiate in 2006 and made his solemn religious profession in 2019.
He has been in Russia since 2011, first at the Novosibirsk seminary and then as a parish priest in Tomsk.
After studying church history in Rome, he completed his doctorate in Russian literature in Tomsk in 2017.
The Diocese of the Transfiguration of Novosibirsk is one of four Catholic dioceses in Russia.
It covers an area of two million square kilometres. Just over half a million Catholics live in the almost 70 parishes of the diocese.
The former Apostolic Administration of Siberia was elevated to a diocese in 2002.
The first bishop was the Jesuit Joseph Werth, a Russian-German born in Kazakhstan. Novosibirsk previously had no auxiliary bishop.
