It was the Catholic Church's mishandling and cover-ups of the scandals that he felt was the most flagitious of the sordid goings on, and it soured his sacerdotal aspirations, leaving him bereft of his sole source of solace after he learned that his wife had been exploring her Sapphic desires at their beach-side pied-à-terre without ever offering to let him watch.

In a blisteringly epiphanous moment of meditation Brother Throckmorten became profoundly aware of the Sapphic tendencies of his feminine side and immediately left the sacerdotal life of the Brothers of the Rapacious Shroud for a pied-a-terre in Montmartre and a questionable relationship with a “retired” Courtesan reputed to have an extensive and flagitious history with the sexually ambiguous Gran Duchess of the Duchy of Gran Fenwick.

The sacerdotal behaviour of the ordinands with Sapphic sexual influences living in the pied-a-terre upstairs is in my opinion criminally flagitious. (by barrydunnage)

Although she had long ago rejected a church that condemned her orientation as flagitious, Linda retained her love for sacerdotal aesthetics and she let it influence her pursuit of the Sapphic pleasures, dressing in silk robes, lighting incense, and illuminating her pied-à-terre with votive candles when dates came to visit.

"Violet tiaras, braided rosebuds, dill, and crocuses", intoned the sacerdote Sapphically, practicing in front of the bedroom mirror in her Roman pied-a-terre in preparation for her testimony in front of the Committee on Women's Ordination (all male and all ultra-conservative) who had called her behavior "flagitious" the last time she'd appeared, which was really rich, coming from a group with an unapologetic predilection for little boys.

Attention ladies! - Sapphic pied-à-terre now available on idyllic Lésvos, possibly suiting adventurous neophytes and acolytes of flagitious persuasion (local facilitation provided, all sacerdotal unguents extra, no epicenes or trannies, odes blessed by request). (by Bud Myte)

At eleven, I thought it made complete sense that Father Johnson and Mother Rose had a pied-a-terre in town, far from the ruckus of her convent where the Sisters, robed in scintillating sacerdotals, danced gaily and sang Sapphic songs, so I didn't understand why the older students sniggered about it like it was something flagitious.
