From CNA:
Archbishop Edward Weisenburger of Detroit announced Wednesday that parish churches in the archdiocese that offer the Traditional Latin Mass (TLM) will be unable to do so after July 1, citing the Vatican’s 2023 clarification that diocesan bishops do not possess the authority to allow the TLM to be celebrated in an existing parish church.
A prominent Detroit shrine will still be able to offer the TLM, however, and Weisenburger said he intends to identify at least four non-parish locations in the archdiocese where the TLM can be celebrated.
