Christian Schaller (born 1967) is a German Roman Catholic theologian from Munich. In June 2013, he was co-recipient, with Richard A. Burridge, of the Ratzinger Prize.

Life
Schaller was born in Munich in 1967. He studied at the faculty of theology of the Ludwig Maximilian University of Munich. Already during his diploma thesis (Diplomarbeit), he dealt with one aspect of the theology of Joseph Ratzinger, soon to be Benedict XVI: The Eucharistic Ecclesiology in the context of the sacramentality of the Church was the title of the paper presented by Gerhard Ludwig Müller.

From 1997 to 2000, he was a research associate professor of systematic theology for future secondary school teachers at the Ludwig-Maximilians-Universität in Munich and the Research Project known as Religion: the history a fundamental concept in modern Christianity from Antiquity up to the twentieth century.

During his period as a research assistant of the chair of dogmatic theology (2000–2003) at the University of Munich, he produced his doctoral thesis showing that, compared to the nineteenth century, which ecclesiological developments led to an intense aggiornamento of the Church in the Second Vatican Council and were included in the Constitution on the Church Lumen gentium. In the foreground is an analysis of the concept "sacramentality of the Church" in the New Testament and its coordinates in the history of theology as well as its systematic exposure to the nineteenth and twentieth centuries.
