Dom Prosper Louis Pascal Guéranger, Servant of God, was a Benedictine priest, abbot of Solesmes Abbey (which he founded in the disused priory of Solesmes) and founder of the French Benedictine Congregation (now the Solesmes Congregation). Dom Guéranger was the author of The Liturgical Year, which covers every day of the Catholic Church's Liturgical Cycle in 15 volumes. He was well regarded by Pope Pius IX, and was a proponent of the dogmas of papal infallibility and the Immaculate Conception. Dom Guéranger is credited with reviving the Benedictine Order in France, and revitalizing the Tridentine Mass.
June 7, 2023: Although I am late to post this, Volume 8 ended on May 31st and the Saint Feast days now goes to The Liturgical Year: Volume XII - Time After Pentecost - Book Three. I am sure it was much easier to follow when this actually was the Church calendar, but there is enough here which is still the same. And the rich history makes it all worthwhile!
May 4, 2023: For the last few days I have been enjoying the readings about the feast days most. In some cases, they are the same as what we still celebrate, but there are also changes, minor and major shifts and deletions, things we no longer even recognize. What a loss! Here is the line-up for the first few days of May so you can see what I mean: May 1 – Saints Philip and James the Less, Apostles May 2 – Saint Athanasius, Bishop and Doctor of the Church May 3 – The Finding of the Holy Cross, also, Saint Alexander, Pope and Martyr May 4 – Saint Monica, Widow But it is not just the changes which are so interesting, there is a plethora of fascinating information as well as rich liturgical reading and prayers for each day! Beautiful!
The wonderful thing about these is that they are day-by-day exegesis. Unfortunately, they do not necessarily match the current Masses and readings we have now, but somehow that doesn't matter, they are still fascinating and enriching.
