Discussion of the relationship between art and liturgy is nearly as old as the Church itself. At root it is a matter of the theological seriousness of the liturgy, balanced against the distinctive aesthetic demands of art making and those individuals gifted with the ability to produce works of art. Notwithstanding a glorious heritage of sacred art and music in the Church, tensions have historically manifested, and still do. Equally, the stipulation that art must serve the liturgy can engender a sense that it is an addendum: helpful, even beautiful, but ultimately subservient. In this essay, I set aside more familiar arguments as to why the Church and art need each other. Instead I consult three important twentieth-century figures: Jacques Maritain (1882–1973), Joseph Ratzinger (1927–2022), and David Jones (1895–1974), who provide a range of complementary reasons why the two spheres should be intimately connected. For Maritain, who holds an expansive view of Christian art, liturgy is a transcendental archetype. Ratzinger insists that art and music should apprehend and portray the cosmic significance of Christ in the liturgy; and Jones gives an anthropological basis to the uniquely work-making character of the person – supremely articulated in sacramental action.
