India: Italian Missionary and Tura Diocese’s First Shepherd, Bishop Marengo, Declared Venerable

Pope Leo XIV declared Bishop Orestes Marengo, SDB, Venerable, recognizing his heroic virtues and advancing the sainthood cause of the Italian Salesian missionary who devoted decades to Catholic communities in northeastern India, particularly in Meghalaya’s Garo Hills.

The Vatican announcement on October 24  marks a significant milestone for the Diocese of Tura, where Bishop Marengo served as apostolic administrator from 1969 and continued living among local communities long after completing his administrative responsibilities.

Located in Meghalaya, a state in India’s northeast, the Garo Hills are home to a substantial Catholic population. During Bishop Marengo’s missionary years, difficult terrain, limited road connections, and inadequate public services made pastoral outreach to remote villages challenging.

He traveled extensively to accompany communities, strengthen the Church’s presence, and support the development of parishes, schools, and health services. His work helped establish foundations for the growth of Catholic life in the region.

After his tenure as apostolic administrator, Bishop Marengo chose to remain in the Garo Hills rather than return to Italy. He continued guiding clergy and religious and accompanying the people he had served for decades.

He died in Tura on July 30, 1998, at the age of 91. His death was widely mourned by the communities among whom he had spent much of his life.

Born in 1906 in Cuneo province in northern Italy, Marengo entered Salesian formation in Turin at age 13. The Salesians of Don Bosco, founded by St. John Bosco, emphasize education, evangelization, and service to young people, particularly those in vulnerable communities.

In 1923, at age 17, he traveled to northeastern India with eight fellow novices. While continuing his philosophical studies, he engaged with rural communities, learned local customs, and helped prepare people for baptism. He was ordained a priest on April 2, 1932.

His missionary service extended beyond Meghalaya. In 1951, Pope Pius XII appointed him the first bishop of the newly established Diocese of Dibrugarh, in Assam. He received episcopal ordination at the Basilica of Mary Help of Christians in Turin on December 27 that year.

He later served as bishop of Tezpur from 1964 until his appointment to Tura in 1969, contributing to the development of Catholic institutions across northeastern India.

The title Venerable recognizes a candidate’s heroic practice of Christian virtues and represents an important stage in the Catholic Church’s canonization process.

The next step toward beatification ordinarily requires the recognition of a miracle attributed to the candidate’s intercession. A further miracle is generally required for canonization.

For the Diocese of Tura and Catholics across Meghalaya, the declaration brings renewed attention to Bishop Marengo’s legacy of missionary service, pastoral commitment, and solidarity with local communities.

His life connected Italy with northeastern India through decades of work among people facing geographical and social challenges. His recognition as Venerable highlights a missionary legacy that continues to hold significance for the Church in the Garo Hills and beyond.
