In 2014, it became the first and for now the only one Polish diocese since a very long time where no deacon was ordinated a priest. About 31.3% of all Catholics in the diocese attend Sunday mass, which is lower than the average for the Polish nation as of 2013.
In the summer of 2020, Piotr M., a priest of the diocese, was convicted of sexually molesting two girls in the village of Ruszów. Investigations revealed that there had been allegations of abuse against him from 10 accusers dating back more than 30 years while he served in the Archdiocese of Wroclaw. A spokesman for the Diocese of Łowicz said that since his conviction Piotr M. has been barred from celebrating Mass or presenting himself as a priest.[4]
In 2024, the Nunciature to Poland said that Bishop Andrzej Dziuba was told to resign because of management issues, "in particular negligence in handling sexual abuse cases committed by some clergy against minors". He had failed to report a case of such abuse to local authorities.[5]
