The Heart of Jesus Order, formally known as the 'Congregatio Sacerdotum a Sacro Corde Jesu', was founded in 1878 by French priest Léon Gustave Dehon. This religious community emphasizes Catholic devotion to the heart of Jesus, symbolizing His boundless love for humanity. The order's new leader, Heiner Wilmer, is a member of this community, highlighted by his official title which includes the order abbreviation SCJ.

The Heart of Jesus Priests are committed to serving people in need, participating actively in social work and education. Their motto encourages outreach to the community rather than isolating themselves in traditional church roles. This focus on social engagement is evident in various institutions they operate, including the Leoninum High School in Handrup, where Heiner Wilmer was once a student and later served as principal.

With a global presence, the order continues to expand its efforts in education and social outreach. The article sheds light on the significance of this order within the Catholic Church and underscores its role in promoting social justice and community welfare in line with its spiritual mission.
