An interesting book which someone wanted me to read. They had read it and was impressed as they had been to the Holy Land a few times and thought it was an important collection of reflections about the Old City of Jerusalem and the last moments of Jesus on the cross.
The book is actually outdated theologically (pre Vatican II). It is interesting in that it is a reflection from the author's own living in Jerusalem and becoming aware that archeological insights can add historical context to anyone's prayer on the death of Jesus. The book has an imprimatur & nihil obstat.
Sertillanges spends some time on the character of Judas but leaves him as a conflicted person who tore himself apart, literally. The final sections are the most poetic and where his French sensibility and command of language is best utilized. He does fall victim to conflating Mary Magdalene with a prostitute (correspondance theory) and the blood libel on the Jews as well as a few other distractions like the Virgin Mary as the Co-redemptress. I'm not sure I would recommend this to other people especially if they were unacquainted with other points of view of Catholic theology but it gave me food for thought, and, considering when it was written (1930), ahead of its time. The book relies heavily on the map layout of the reputed area of Golgotha.
I found the best part of the book to be the final chapters where he wasn't focused on Jesus overlooking the city from the cross but reflecting on the resurrection and the promise of the sealed tomb.
The author is a French Dominican who edited the Revue Thomiste.

These pages will intensify your love of Jesus by burning the events of His Passion into your memory and imagination.

Written by a priest who lived in Jerusalem and spent many a day walking and praying in the streets where Jesus walked and prayed, this famous devotional classic gives you vivid details not included in the Gospels; and it brings the Gospel events to life for you in unexpected ways.

With Jesus, you'll be jostled by crowds as you enter Jerusalem, choke on the dust of the narrow streets, smell the exotic scents of the city at festival time, share the Last Supper with the disciples, stare into the faces of HIs accusers, and look down at the milling crowd as He dies on the Cross.
