Fabris joined the Association of the Daughters of Mary in the parish church of Marola and was a devoted member. She faithfully observed the practices of the group and, as time went on, she grew to express great love of Mary, the mother of Jesus. Her favorite devotions were to the Holy Spirit, the infant Jesus, the Cross of Christ, the Eucharist, and the Virgin Mary, and praying for the souls in the Purgatory. She was known as an agent of good will in her family, among her friends, and in her parish, where she taught catechism to the children and sewing to the girls who came to her home.
