[1][2] He was also the co-founder of the Oblates to the Divine Love which he established alongside the Servant of God Margherita Diomira Crispi.

He was later titled as Venerable in 1991 after Pope John Paul II confirmed that he had lived a life of heroic virtue.

For months the seminarians ate onions and sometimes starved, but he was noted for keeping his fellows occupied with his good humor.

[2] Intreccialagli was ordained into the priesthood in 1875 in the Civita Castellana Cathedral by the diocesan bishop, and after ordination lived for a time in the convent attached to Santa Maria della Vittoria while finishing his studies at the Pontifical Gregorian University.

[2] He later became the prior for Santa Maria della Scala in 1885 (he was re-elected in 1888) and after that term expired spent a brief period in both Caprarola (to teach) and Montecompatri (as the vicar for the San Silvestro convent from 1883 to 1885).

[1][2] He opened a new convent in Ceprano in 1893 and later allowed in 1906 for the order to return to the ancient Basilica di San Valentino in Terni.

In Caltanissetta he helped to fund orphanages and travelled to the salt mines to wait for the miners to finish work all so he could meet with them and talk to them.

[1] In 1911 the pope named him as an administrator for the Monreale archdiocese since the archbishop there could no longer perform his duties due to advanced age (he was in his nineties).

He heard confessions each morning in the church of Saint Joseph and oversaw spiritual guidance for people such as Venerable Marianna Amico Roxas.

In June 1924 he returned for rest to his hometown but later travelled to Palermo that September in order to attend the National Eucharistic Congress that was to be held there.

Intreccialagli was named as Venerable on 22 January 1991 after Pope John Paul II confirmed that the late bishop lived a model life of heroic virtue.
