David Haas

David Haas is an American composer and songwriter widely known within Catholic and Christian liturgical music circles for writing contemporary hymns and worship songs used in parishes across the English-speaking world. Songs such as «You Are Mine», «Blest Are They», and «We Are Called» became staples of modern Catholic liturgy, prized for their singable melodies and accessible, scripturally rooted lyrics that made them easy for congregations to adopt.

Haas's music belongs to the contemporary liturgical and folk-influenced worship tradition that grew out of post-Second Vatican Council reforms, emphasizing communal singing, guitar and piano accompaniment, and lyrics drawn directly from psalms and gospel texts. His compositions were widely published in hymnals and worship resources, making his work part of the everyday musical life of many Catholic congregations for decades.

His work sits at the intersection of songwriting and ministry, reflecting a broader movement of composers who shaped how English-speaking Catholic communities sing together, rather than pursuing mainstream commercial success.
