Isfrid of Ratzeburg was a Premonstratensian cleric who served as the third bishop of Ratzeburg beginning in 1179. Born around 1200, he previously held positions as a canon at Cappenberg monastery and as the Provost of Jerichow. He was recognized for his administrative talents, specifically his ability to establish various parishes and his efforts to rebuild the monastery of Floreffe after a fire. He died in Ratzeburg on June 15, 1204.
Religious career

Before his elevation to the bishopric, Isfrid completed the construction of the Romanesque collegiate church in Jerichow. Following the destruction of the Floreffe monastery, he successfully gathered the scattered canons back to the community. His leadership extended to consecrating the collegiate church of Postel in Belgium. Historical records describe him as a man characterized by fortitude, humility, and Christian wisdom.
Veneration

Isfrid is recognized as a saint and is commemorated on June 15. In the diocese of Osnabruck, he has long been honored, a tradition the Premonstratensian Order received official confirmation for in 1725. Artistic depictions of the bishop often portray him performing miracles, such as healing a blind man or transforming water into wine.
