A Catholic Hymnal is a collection of hymns and songs used in Catholic worship services. It serves as a guide for congregations to sing praises during Mass and other religious ceremonies. The hymns often reflect themes of faith, love, and community, and are an important part of the Catholic Church's liturgical tradition. These hymnals typically include music notation, lyrics, and sometimes additional information about the hymns' origins or meanings. They are used in various settings, from Sunday Mass to special celebrations like Christmas and Easter, helping to enhance the spiritual experience of the faithful.
