Venerable Bertilla Antoniazzi (1944–1964) was an Italian laywoman whose brief life was marked by profound faith and resilience in the face of chronic illness. Born on November 10, 1944, in San Pietro Mussolino, Vicenza, she was the eighth of nine children in a devout farming family. At the age of nine, Bertilla was diagnosed with rheumatic endocarditis, a severe heart condition that led to frequent hospitalizations and ultimately confined her to her home. Despite these challenges, she maintained a serene and compassionate disposition, deeply rooted in her Catholic faith.

Embracing her suffering as a vocation, Bertilla dedicated herself to consoling fellow patients and offering her hardships for the spiritual benefit of others. She engaged in extensive correspondence with other sick individuals, providing them with comfort and spiritual support. Her devotion to prayer and the Eucharist was unwavering, and she found solace in entrusting herself to Our Lady of Monte Berico, a Marian devotion significant in her hometown. In 1963, despite her deteriorating health, she undertook a pilgrimage to Lourdes, where she sought not physical healing but the grace of holiness.

Bertilla's life, though short, left a lasting impact on those who knew her, exemplifying how faith and acceptance of suffering can transform personal trials into a source of spiritual strength for oneself and others. She passed away on October 22, 1964, in Vicenza.
