The calls on Pope Francis not to impose fresh restrictions on the Traditional Mass have been joined by two more joint letters. Both have been published with the same intention as the open letter by Scottish Catholic composer Sir James MacMillan that was published 3 July in The Times to much acclaim.

First, a letter from a retired Mexican Cardinal, Juan Sandoval Iñiguez, which had been sent to Pope Francis a week ago, has been published, together with a "Letter of Adherence" signed by 67 personalities from around the world.
