Angelus is thought to have been one of the first Carmelites to return to Sicily from Mount Carmel and, according to a long-standing tradition, he was murdered in Licata during the first half of the 13th century.

Venerated as a martyr, a church was built soon after his death at the place where he died and his body was interred there. Only in 1662 were his remains transferred to the Carmelite church in Licata.

The cult of Saint Angelus spread throughout the Order and among ordinary lay people. Angelus and St Albert of Trapani are considered the "fathers" of the Order because they were the first two saints to have a cult in the Order and, as a result, they are frequently found in medieval Carmelite iconography alongside the Virgin Mary.

In Sicily, there are many places which have adopted Saint Angelus as their patron and the people there turn to him when in need, with great love and affection.

Holy God,
strength of the faithful and crown of martyrs,
by your grace Saint Angelus was called from Carmel
to triumph victorious over the torments of martyrdom.

By his prayers grant us
that faithfully following his example
we may bear witness to your presence and goodness until death.

Through our Lord Jesus Christ, your Son,
who lives and reigns with you in the unity of the Holy Spirit,
God, for ever and ever. Amen.
