I don’t really know too much about this ( these?) devotions, but one has been around for quite some time, and is almost universally accepted by the Church.
The other ( that I know about) began in the early 1990’s, when a young Nigerian man began having visions of Jesus and Mary. This seer, Barnabas Nwoye, was still in his teens when these visions began. There are quite a few " Warnings" and a series of pilgrimage sites, the Holy Land and the original vision sites in Nigeria, which must be visited by devotees in a prescribed length of time.
What bothers me most about this devotion is the cost that it may entail, also, some sacramentals unique to this practice seem extreme and judgmental. There is a crown of thorns ( how it is used, I don’t know), an agonizing crucifix which depicts the Savior in extreme suffering, and some smaller items. Also, for a certain time, maybe once a month, devotees much stay awake, praying, until 3AM. From an earlier post here, it seems that children are expected to participate, as well as adults. Devotees must be accepted by a priest, but no other rules apply, such as kids being allowed to sleep or study on school nights.
In short, it seems quite negative in tone. Yes, Jesus suffered great pain for us…but it seems as if the suffering is being placed ahead of the results. It just seems rather bizarre.
Also, the American devotion is undergoing some changes, including a dispute over which prayer book to use.
Also, I believe that the writings of Nwoye are accepted by his local bishop…the sacramentals, and other parts of the devotion.remain unapproved.
We’ll, I’m certainly no expert…but I have come across it on different sites, and when I saw two threads on this forum, I thought I should speak up. If you’re involved with this, I advise caution…but that’s just me. I’ve found no criticism of the older practices.
