Dionysius
An eclipse darkened the skies when Jesus that day died, Dionysus being present. May the Light His Resurrection brought shine once again in contemporary Christian countries like Dionysus made possible the encounter between Greek wisdom and Christ's message, bringing out the fruit of the first.

Francesco d'Assisi

What can we pick from his well known life? maybe the wolf he soothed in Gubbio.Thoughts to some contemporary aggressive lobbies...

 Petronius - Bishop

Lived at the times of the barbaric invasions...

Tullia
In the times when married men were allowed to the Bishopry (did not say good times ;)), Tullia was the saintly daughter of such and sister to another saint...the notes of a well known song in Italian come to mind

santa  la moglie santa la figlia santa la figlia della sorella era santa pure quella...
(lyrics changed)

Bruno 
Founder of the chartreuse where monks lived in laborious silence...how much silence is there in some communities, but of the hostile pent up envies etc type? time for some self taming?

Augustus
A paralytic he was made abbot of a monastery after recovering the use of both arms and legs, without which he built a hermitage dedicated to Saint Martin of Tours who had made the miracle possible. How? raisng the money needed with begging.

Pelagia

Had I not taken a friend out to choose the right jacket for the Vatican...I would have said that the Bp life changing reminder to Pelagia that it is the adornment of the soul what really  matters applied just to the ladies ;)
