In January 2021, the diocese instituted a policy for schools, parishes, and charities to affirm the biological sex of all persons. This includes the use of pronouns, requiring that bathrooms and sports be segregated according to biological sex, and requiring school officials to avoid participating in the administration of hormonal treatment designed to alter sexual characteristics of students. It affirms the reality and discomfort of gender dysphoria, and for its treatment, the diocese recommends counselors who "hold a correct Christian anthropology of the human person and understand and adhere to Catholic teaching."

Michigan Attorney General Dana Nessel, who charged the priests, stated that four of them have been arrested in Arizona, California, Florida and Michigan, and the fifth awaits extradition from India. The Diocese of Lansing stated that the priest who was arrested in Florida, Father Vincent DeLorenzo, had eight people accuse him of sexual abuse while serving in the Diocese. DeLorenzo, who is now 80 and who resigned from the Diocese in 2002, is charged with six counts of both first and second degree sexual misconduct and is also undergoing the process of being defrocked. A sixth priest who faces an administrative complaint has had his counseling license suspended by the state.
