Giacinto Bonaventura Longhin (22 November 1863 – 26 June 1936) - in religious Andrea di Campodarsego - was an Italian Roman Catholic prelate and professed member from the Order of Friars Minor Capuchin who served as the Bishop of Treviso from 1904 until his death.

This cause materialized in 1964 and resulted in the declaration that the late bishop was Venerable in 1998 after Pope John Paul II confirmed his heroic virtue.

In his childhood he felt drawn to the priesthood and he entered the Order of Friars Minor Capuchin despite the protests of his father.

He assumed the religious name "Andrea di Campodarsego" on 27 August 1879 after vesting in the habit in Bassano del Grappa in Vicenza (beginning his novitiate period).

He travelled often to each parish in order to become close with his people while he set about reforming the seminaries to improve spiritual formation while seeking to encourage vocations.

[1] Following the war he worked with social movements and was made as the apostolic visitor to Padua in 1923 at the direction of Pope Pius XI.

Pius XI in October 1923 acknowledged the "great services" the bishop rendered for the flock and said that "he has worked so much for the Church" through his apostolic zeal.

[3] In 1929 the Cardinal Patriarch of Venice Pietro La Fontaine wrote that Longhin exemplified "the Good Shepherd in the Gospel" who remained "true to the original".

He likewise - in April 1914 - declared to be sacred "the right of workmen to organize themselves ... in unions for their own economic and moral upgrading".

In 1920 he supported the Christian union movement known as "Leghe Bianche" and came to oppose fascism after Benito Mussolini secured power in late 1922 after his march on Rome.

His funeral was held on 30 June with a large crowd amassing to farewell him; Longhin's remains were interred in the Treviso Cathedral later on 5 November 1936.

Longhin was declared to be Venerable on the following 21 December after Pope John Paul II confirmed that the late bishop had lived a model Christian life of heroic virtue.

John Paul II - a week later on 23 April - confirmed this miracle as such and beatified Longhin in Saint Peter's Square later that 20 October.
