In 1884, Caruana was received as a
postulant of the monastic community, and received the
monastic habit on March 21 of that year, celebrated by Benedictines as the
feast day of St. Benedict, the founder of the Benedictine Order, and being given at that occasion the
religious name of
Maurus, after one of the founder's most noted disciples. He made his temporary profession of
religious vows the following year, and he made his
solemn vows three years later, on 11 November 1888. He then pursued his study of theology and was
ordained a
priest on 14 March 1891 by
Hugh MacDonald,
C.Ss.R., the
Bishop of Aberdeen. He was then sent to pursue his ecclesiastical studies in
Rome at
San Anselmo College, an international center of studies run by the Benedictine Order. After his return to his abbey, Caruana taught philosophy, theology and Latin literature at the abbey school. In 1899 he was appointed a
parish priest at
Dornie, western
Ross-shire, in the
Scottish Highlands, for which he learned
Gaelic to care for a widely scattered flock. In 1904, due to his talents and training, he was chosen to act as private secretary to the Maltese bishop,
Ambrose Agius, O.S.B. (1856–1911), another Benedictine monk, who, at the time, was
Apostolic Delegate to the Philippines. This was to be his only experience of higher ecclesiastical office before he was appointed bishop. In 1906, Caruana returned to Fort Augustus Abbey, where he was appointed choir master for the community. He also engaged in a preaching ministry in various locales in Scotland and England over the next few years, including
Westminster Cathedral in
London, where he preached a course of
Lenten sermons. He was especially welcome by the Italian immigrant community of the United Kingdom for his proficiency in their language. ==Bishop==
