Sacred Heart (Christian devotion)

Historical development

The modern form of the devotion developed in the 17th century. A key figure in popularizing it was Saint Margaret Mary Alacoque, a French Visitation nun, who reported private revelations in which Christ asked for devotion to his heart and specific practices such as the Holy Hour and Communion on the first Fridays. Earlier proponents and theological reflections on Christ's loving heart appear in medieval and early modern spirituality, and the devotion expanded through religious orders, confraternities and devotional literature.

Symbols and common elements

Artistic depictions convey theological meanings. Common attributes are:

• a visible heart, often aflame, signifying burning love;
• a crown of thorns or wound, indicating suffering and sacrifice;
• a cross above or within the heart, linking love to redemption;
• sometimes streams of light or blood, evoking Eucharistic and sacrificial themes.

Practical expressions and observances

Devotional practices associated with the Sacred Heart include personal prayers, consecration of individuals or families, the enthronement of an image in homes, communal acts of reparation, and the practice of Receiving Communion on nine First Fridays. The Feast of the Sacred Heart is observed liturgically on the Friday following the second Sunday after Pentecost. Devotional societies and parish groups continue to promote these practices in many countries.

Significance and distinctions

Theologically the devotion emphasizes God's intimate, personal love and invites a response of trust, love and penance. It is distinct from, though related to, the devotion to the Immaculate Heart of Mary, which focuses on Mary's interior life and maternal love. Within Christian art and popular religion the Sacred Heart became a widespread emblem of piety, social identity and charitable inspiration.

Notable figures and resources

Saint Margaret Mary Alacoque is the most associated individual; other priests, religious congregations and lay movements helped disseminate the devotion.

The devotion remains an active element of contemporary Catholic spirituality, teaching, and parish life.
