The Order of Clerics Regular Minor (Latin: Ordo Clericorum Regularium Minorum), commonly known as the Caracciolini or Adorno Fathers, is a Roman Catholic religious order of priests and brothers founded by Francesco Caracciolo, Giovanni Agostino Adorno, and Fabrizio Caracciolo in 1588 at Villa Santa Maria, Abruzzo.

Belonging to the family of Clerics Regular, its members desired to sanctify themselves and the People of God by imitating in their lives the Paschal Mystery of Christ.

Two events could be said to have contributed to Adorno's decision to abandon his career as a banker and financial manager of the family's business: he lost a large amount of money gambling, and the death of his father in 1578.

He continued to exercise his pastoral ministry as a member of the Confraternity of the White Robes of Mercy in Naples, reaching out to the prisoners.

After obtaining a law degree and with the prospect of a brilliant career as well as a comfortable life, he chose instead the clerical state and was ordained a priest.

At twenty-two, Ascanio Caracciolo was a young man enjoying the exceedingly comfortable life available to an Italian nobleman of the sixteenth century, when he contracted a terrible skin disease.

Facing death, he vowed that if he recovered he would give the rest of his life to God, and after his miraculous recovery he immediately began studying for the priesthood and was ordained in 1587 at the age of twenty-five.

In addition to the three evangelical counsels of chastity, poverty and obedience, they contemplated a fourth vow: the renunciation of any ecclesiastical dignity.

Members of the congregation, called the Clerics Regular Minor, took the usual vows of poverty, chastity, and obedience, plus a fourth: not to seek any ecclesiastical office either within or outside the order.

The priests kept perpetual adoration before the Blessed Sacrament and conducted missions, helped the inmates of hospitals and prisons, and established hermitages for those who felt called to a life of contemplation.

Augustine Adorno and Francis Caracciolo made their religious profession in the chapel of the White Servants of Mercy, I Bianchi in Naples on April 9, 1589.

Most of the responsibilities and concerns of the new religious family fell upon Francis Caracciolo, who became the first superior general and the focal point of reference for everyone.

By the end of this century, the order has grown to five Provinces (three in Italy and two in Spain) and has about 50 communities with a total membership between 700 and 800 religious.

The French Revolution, the suppression of religious orders, the nationalistic spirit of the times, and other factor contributed to the general disarray and deterioration.

Contacts were made with various dioceses, and the order accepted an offer from the Bishop of Charleston, Ernest L. Unterkoefler, to open a new apostolic work at Immaculate Conception Parish, Goose Creek, South Carolina.

The first missionary foundation of the Adorno Fathers was on February 19, 1984, in the Democratic Republic of Congo (Ex Zaire) with Parochial Ministry in Binja in Nyamilima followed by the opening of the Seminary of St. Joseph in Goma.

Following an invitation by Bishop Benjamin J. Almoneda, a group of Adorno priests went to the Diocese of Daet with the understanding of using the academic diocesan facilities of Holy Trinity College Seminary.

The first group of students together with the Adorno priests took up residence temporarily on the campus of Holy Trinity, while the House of Formation was being built in Vinzons, Camarines Norte.
