I hope this is nut just a bunch of seminarians birettas from a traditional Order or insitutute, but a growing practice among young Roman priests.To see it in a traditional Institute is no surprise....but to see it groing as a practice among young priests in general...now that would be something to photograph and cheer about!
One wonders why so few birettas ever show up at pontifical services except for prelates.
I think you have cleaned the pew and put these caps in order to take the picture...http://fotos.miarroba.es/fo/23a0/1D4E1ED934274DDFD9FB264DDFD62E.jpg
As a Roman seminarian, I can tell you that the tradition of wearing the biretta is growing among young priests.
I put them in order last thursday. I like that you appreciate it!
Young priests in Rome may be embracing the fad of biretta-wearing but if they are the products of Roman seminaries they certainly will be cautious since ambition and careerism are equally infectious there. After all, the mess we are in happened because clerics were fixated on what direction the winds were blowing and whose favor they could curry.
What about the cappello Romano ("saturno")? Wasn't that the preferred item for clerics in Rome?
