The lay brother, Isidore of the Nativity of Mary (Giacomo Antonio Sciuti) was born in Carpeneto, in the province of Alessandria, Italy, on 8th of July 1696. At the end of the period of formation in the novitiate of Santa Maria della Scala in Rome, he made his profession of religious vows on 9th of September 1723, in the hands of Fr Bernard Mary of Jesus.
Called a few years later to the monastery of Santa Maria della Vittoria, he exercised the office of seeking alms, distinguishing himself by his particular inclination to the interior life consisting of prayer, silence, humility and charity. Thus in 1737 «driven by an ardent love for the Order of Carmel, he became part of the current active and popular apostolate of his time, gathering a group of young people who dressed in the habit of the Carmelite Third Order, and with the authorization of the Superiors, sent them to various cities in Lazio, Marche and Campania which formed part of the Papal States». The task of these Sisters was to impart to the girls gathered in their homes and schools «the teaching of the first elements of the faith, educating them at the same time in piety and instructing them in women's work activities, not without a healthy and simple human and Christian pedagogy».
On December 23, 1769, at the age of 73, he went to celebrate the Nativity of the Lord in heaven.
