In crafting this distinguished seal, we were honored to engage the services of Karr Cedric, a renowned heraldist of Arca Foederis in the Philippines. His expertise has been sought by esteemed institutions such as the Archdiocese of Manila, the Archdiocese of Cebu, and the Minor Basilica and Parish of St. John the Baptist in the Diocese of Antipolo. Karr Cedric was chosen not only for his masterful craftsmanship but also for his deep understanding of Bishop Lumanog’s cultural heritage as a fellow Filipino. This seal reflects not just episcopal authority, but also the unique legacy and mission of a Filipino-American bishop entrusted with upholding the faith.
The Episcopal Seal of Jon Ignatius Lumanog
The episcopal seal of Bishop Jon Ignatius Lumanog is a profound visual testament to his faith, heritage and mission as a bishop. Rooted in Christian symbolism and personal significance, the seal integrates elements of his spiritual calling, theological convictions and family name.
Shape and Overall Design
At the heart of the seal is a traditional episcopal shield, symbolizing leadership, guardianship and divine protection. Crowning the shield is a bishop’s mitre, signifying episcopal authority and the sacred duty of teaching and shepherding the faithful. Behind the shield, a crosier (shepherd’s staff) represents pastoral care, while a key—the symbol of St. Peter—denotes apostolic succession and ecclesiastical authority, echoing Christ’s words in Matthew 16:19: “I will give you the keys of the kingdom of heaven.”
The Shield’s Elements and Symbolism
The shield itself is divided into two halves, each carrying profound theological and personal meaning.
Left Half – Faith and Sacraments (Purple Background)
The left side of the shield, set against a purple background, embodies Bishop Lumanog’s deep commitment to Scripture, sacramental life and the Holy Spirit.
- Cross of St. George (White & Purple) – A traditional symbol of Christian faith, referencing Anglican heritage. The color purple signifies episcopal authority as a bishop.
- Open Book with Alpha (Α) & Omega (Ω) – Represents the Bible and Christ as the eternal Word (Revelation 22:13), underscoring the bishop’s dedication to theological wisdom and the teaching ministry.
- Chalice – A symbol of the Eucharist, highlighting the centrality of sacramental life in his episcopal mission.
- Flame – Represents the Holy Spirit, divine inspiration, and an unwavering passion for ministry and missionary zeal.
Right Half – Family and Name Symbolism (Blue, White & Red with a Golden Eagle)
The right side of the shield integrates personal and familial significance, reflecting his heritage and patron saints.
- Golden Eagle with Halo (Symbol of St. John the Evangelist) – The eagle, emblematic of St. John, represents spiritual vision and divine revelation. It also serves as a personal connection to Bishop Lumanog’s Christian name, “Jon.”
- Rayonny Division (Flames) – Symbol of the Lumanog Name – The flame-like rayonny pattern references the meaning of Lumanog. The surname Lumanog carries a wealth of cultural and historical significance that provide insights into the heritage of individuals who bear this name. Last names often serve as a window into the past, reflecting the geographic, linguistic, and social contexts in which they originated.
The surname Lumanog is believed to have Filipino roots, reflecting the rich tapestry of languages and cultures that characterize the Philippines. The name is thought to have connections to Tagalog and other indigenous Philippine languages. While the exact meaning can vary, it often evokes ideas of brightness or illumination, possibly stemming from the root word “lumi,” which can denote light or brightness in Filipino vernacular. This aspect of the name suggests a heritage linked to positive attributes like enlightenment or clarity.
The flame-like rayonny pattern (flames) symbolizes a mission to bring spiritual illumination to others. - IHS Christogram with Red Sunburst (Symbol of St. Ignatius of Loyola) – The IHS monogram, the emblem of St. Ignatius of Loyola, honors Bishop Lumanog’s middle name and his dedication to Ignatian spirituality. The red sunburst symbolizes Christ’s divine radiance and missionary zeal.
Alternative Interpretation – The Phoenix and Resurrection
A variation of the seal includes a golden phoenix rising from flames—a powerful symbol of resurrection, renewal, and triumph over death. The phoenix represents perseverance, spiritual rebirth, and the transformative power of faith, reinforcing the bishop’s mission of renewal and revival.
Outer White Border and Inscription
Encircling the shield is a white border adorned with black crosses, further emphasizing its Christian significance. Inscribed along the border is the name “Jon Ignatius Lumanog,” affirming his identity and mission as a bishop.
Theological and Personal Significance
Bishop Lumanog’s heraldic seal is more than an artistic representation — it is a visual proclamation of his vocation. The left half highlights his devotion to Scripture, the Eucharist, and the Holy Spirit. The right half pays tribute to his family name and Filipino heritage, patron saints, and the calling to spread the Gospel light. United in purpose, these elements reflect his duty to uphold apostolic tradition, guide the faithful and illuminate the path of Christ for all who seek Him.
