Who they were

In the territory of Astino in Val Camonica in Lombardy, Blessed Guala, bishop of Brescia, of the Order of Preachers, who, in the time of the emperor Frederick II, worked wisely for the peace of the Church and of civil society and was condemned to exile.

The miracles

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

Why that counted as sanctity

The Roman Martyrology remembers him on 3 September as a Dominican bishop of Brescia who worked for peace in Church and society and was exiled.

The cause

Guala de Roniis has been beatified; the cause continues. Favours received, and offers of help, go to the postulation, the office that carries the cause forward: Dominicans: Blessed Guala of Bergamo.

A miracle approved by the Holy See is needed for the next step. Reporting one begins with the postulation.
