Albert, called by God's favour to be patriarch of the church of Jerusalem, bids health in the Lord and the blessing of the Holy Spirit to his beloved sons in Christ, B. and the other hermits under obedience to him, who live near the spring on Mount Carmel.

Thus begins the Rule of St. Albert, the "Holy Rule" of the entire Carmelite Order. The "B" whom St. Albert is addressing was long considered to be St. Brocard, the prior of the Carmelite community on Mount Carmel who requested a rule of life for his community from Albert, the Latin Patriarch of Jerusalem. This was St. Brocard's feast day from at least the 15th century until the calendar changes that followed that late Vatican Council. St. Brocard no longer appears on the Carmelite calendar. This short summary appears in the current Magnificat:

A native of Jerusalem born to French parents, Brocard became the superior of a community of French hermits living on Palestine's Mount Carmel. He set an example for his fellow hermits with his devout prayers to Christ, the Blessed Virgin Mary, and the saints. He never went anywhere without bringing his stole, his breviary, and his "Paternoster", a set of beads for repeating the Our Father (a predecessor to rosary beads). Once, Brocard was approached by a Syrian Moslem emir, crippled by leprosy, who hoped to obtain a cure. Brocard told him, "Approach the spiritual water of the Jordan, that your body may be washed, and you shall recover your health." The emir replied: "I understand what you say; I wish to be baptized and to be made a Christian." Immediately after being baptized by Brocard, the emir was healed of his leprosy. The emir spent the rest of his life among the hermits on Mount Carmel, devoting himself to God and the Blessed Virgin Mary. Brocard obtained a fixed rule of life for Mount Carmel's hermits, thereby laying the foundation for the subsequent establishment of the Carmelite Order.

The ancient collect for his feast is this:

Sanctifica, Domine, famulos tuos, in veneratione beati Brocardi, Montis Carmeli incolae, Confessoris tui, humiliter supplicantes : ut ejus salutaribus patrociniis vita nostra inter adversa ubique regatur. Per Dominum. Amen.
