Fr. Steiner retired from assigned ministry in 2005. In 2016, the Diocese of New Ulm removed him from all public ministry following notification of a civil claim made against him stemming from his time as pastor at the Church of St. Paul in Comfrey in the 1970s. His removal from ministry was publicized in 2016. No other claimants have come forward with reports against him.
Fr. Bernard Steiner has returned to limited ministry based on the recommendation of the independent Diocesan Review Board following a completed investigation by police that found no substantial credible evidence to support the abuse allegation made against him.
Fr. Steiner is allowed to concelebrate Mass and administer the Anointing of the Sick in the presence of other members of the clergy.
