This reminds me of a scene in Beavis and Butt-Head Do America where Beavis and Butt-Head get on the wrong tour bus (which is filled with nuns), so they go to a Catholic church in New Mexico, and they go to the priest’s seat in a confession room, where other people confess their “sins” to Beavis and Butt-Head. When someone asked Beavis how many Hail Marys the guy has to say, Beavis said 1,000.
Those 150 psalms were all different prayers that would be beneficial in their own unique ways, while 56 Hail Marys is just constant repetition of the same thing that you already know. Not that I even think Mary should be venerated to this degree.
To me, it makes no sense that we’d be more likely to go to heaven by doing something so tedious yet so pointless. Again, even when I thought that I’m Catholic, I always knew that faith alone is all one needs for salvation.
