Cantus Ecclesiae is a carefully curated chant book presenting the essential Gregorian chants of the Roman Rite, intended for seminarians, clergy, church musicians, and parishes seeking a faithful and enduring foundation in the Church’s musical tradition.

The volume focuses on the core chants proper to the Roman liturgy itself—chants that form clergy, foster unity across cultures, and remain stable across generations. Rather than serving as a seasonal or contemporary hymnal, Cantus Ecclesiae functions as a formation and reference resource rooted in the Church’s long-standing practice.

The chants are presented in Latin, accompanied by English and Latin-American Spanish translations provided for accurate comprehension of the texts rather than for singing. This approach makes the book particularly well suited to seminaries, formation programs, and bilingual pastoral contexts.

Because Cantus Ecclesiae contains no Mass readings or vernacular texts subject to revision, it is designed as a permanent resource. It may be used for formation, study, rehearsal, and, where appropriate, as a pew book in parishes where Gregorian chant is regularly sung.
