[4] On 27 October 2020, Pope Francis promulgated a decree[5] approving a miracle attributed to Russolillo; this enabled for him to be canonized on 15 May 2022.
Giovanna, his sister, joined his female order and became the first Superior General, while his brother Ciro also entered the Vocationist and became a priest.
[1][3] In spring 1955 he collapsed several times due to ill health and – on the advice of Doctor De Simone – did not lead the procession for the Corpus Christi on 9 June and on 16 July was instructed by Doctor Cataldi to rest at the Monaldi Hospital in Naples; but from 20 to 27 July he visited novices from his orders with Raffaele Castiglione.
[3] A blood test taken a short time later confirmed that he was dying from leukemia and his mother Giuseppina and his sister rushed from Rome to be with him around this point; he was hospitalized on 1 August.
Russolillo's orders now serves in many nations: in Latin America (Brazil, Argentina, Chile, Ecuador, Colombia), in Africa (Nigeria, Madagascar, South Africa), in Europe (Italy, United Kingdom, France), North America (United States of America, Canada) and in Asia (India, Philippines, Indonesia, Vietnam) as well as in Australia[7] The beatification process commenced on 15 December 1977 under Pope Paul VI after the Congregation for the Causes of Saints issued the official "nihil obstat" to the cause and titled the late Russolillo as a Servant of God while transferring the location of the beatification process from Pozzuoli to Naples on 7 July 1978.
Pope John Paul II named Russolillo as being Venerable on 18 December 1997 after he confirmed that the late priest lived a life of heroic virtue.
Pope Francis in 2020 confirmed a second miracle attributed to him (the healing of the Vocationist religious brother Emile Rasolofo in Madagascar).
