Cardinal Nichols has made a full statement about the implementation of Traditio Custodes in the Archdiocese of Westminster. It can be read in the Archdiocese website. In essence it invites priests of the diocese to to apply for consent to offer the older form of the Mass, and indicates that, subject to some conditions, consent will be granted. The indications are that all existing Latin Masses in the Diocese will continue.
This is good news, as it is likely that similar policies will be adopted by other bishops in England and Wales. Indeed, some have already done so with varying degrees of formality.
However, there is one point that still needs addressing. This is the parts of the Westminster Diocese (and other dioceses) where there is little or no Latin Mass provision. The campaign goes on.
