Bonaventure’s entire theological project is deeply prayerful, and many of his most famous works are bookended by prayer. This is nowhere more evident than the Itinerarium, which begins by advising souls seeking peace to cry out in prayer, and ends with David’s words from Psalm 73—invoking mystical “passing over” into Christ through death. To read Bonaventure rightly is to stand in humility before God, the immeasurable Creator Whom no one can see and still live.
A seemingly less discussed source of controversy within Christendom is the topic of prayers for the departed. In fact, I had never even heard of such a practice until more recent years. I believe that this is primarily due to a gaping paradigmatic difference in the understanding of soteriology [doctrines of salvation] from East to West that eventually led to the dispensing of this historically Christian practice from the memory of contemporary low-church Western traditions.
