Who they were

At Kotor in Montenegro, Blessed Catherine, virgin, who, baptised in the Orthodox Church, entered the Order of Penance of Saint Dominic, taking the name Osanna; she lived enclosed for fifty-one years, immersed in divine contemplation and devoted to prayer of intercession for the Christian people during the Turkish invasion.

The miracles

The Roman Martyrology does not describe the miracles approved in the cause.

Why that counted as sanctity

The Roman Martyrology remembers her on 27 April as a Dominican tertiary who lived enclosed at Kotor for fifty-one years, praying for the Christian people during the Turkish invasion.

The cause

The cause continues. No postulation address is published here yet. Favours received through this person’s intercession, and offers of help, are best sent to the religious order or congregation they belonged to, or to the diocese where the cause was opened; either will pass them to the postulation.

A miracle approved by the Holy See is needed for the next step. If you know the postulation’s own page, tell us and it will be added here.
