The pic shows that this book covers the years 1958-1962, so it does not seem to be an appropriate source:
We need the book covering 1957 (which is what the online source provides), in order to see if there is a discrepancy.
That a turkey indult appears in 1962 does not disprove its prior existence in 1957.
Sean, the online reference says it was taken from Volume 5, which is the volume I just purchased. I’ve looked in Volume 4, which covers 1953-1957, and it has nothing about the supposed “turkey indult”.
Frankly, for R&R adherents, such as yourself, this really is a non-issue since the Vatican II magisterium has quasi-abrogated the Friday abstinence, so I suppose their conscience is clear. It does however pose a problem for those of us who hold the sedevacantist position since it seems to be enacted four years after the death of Pope Pius XII. Also, even if the indult was authorized under Pius XII, one would have to appeal to epikeia in order to partake in it.
