Iosafat was an active participant in the Wallachian Revolution of 1848, serving on a commission for freeing the Roma slaves. As a result, he was forced to flee, first to Transylvania and then to Dobruja, where Metropolitan Dionisie of Proilavia ordained him archimandrite. Iosafat ultimately settled in Paris, where he organized the Romanian community around a chapel at 22 rue Racine. The building was blessed in 1855, and he served there until his death. He was buried in the parochial crypt at Montparnasse Cemetery.
