Archbishop Roche, Secretary of the Congregation for Divine Worship and the Discipline of the Sacraments, cited a letter sent in August by the congregation’s prefect, Robert Cardinal Sarah, in which the cardinal wrote: “in times of difficulty (e.g. wars, pandemics), Bishops and Episcopal Conferences can give provisional norms which must be obeyed … These measures given by the Bishops and Episcopal Conferences expire when the situation returns to normal.”
Hopefully this directive will put the issue to bed once and for all.
