Levantine Rite Istroyan Petrine Conciliar Church

The Levantine Rite Istroyan Petrine Conciliar Church (LEVRIPC), commonly known as the Calixtine or Hessian church, is a minor church in Mellifera. It broke off from the Catholic Church in the 1920s, primarily as a result of disputes over the approach to and theology of Liturgical Renewal and Ressourcement. Liturgically, the church is distinguished from the Catholic Church by its use of the Levantine Rite as it existed in 1922, with certain reforms based on the Audonian liturgy and translated into Koine Istroyan. Theologically, the church rejects Aristotelianism, Purgatory, Transubstantiation, papal supremecy, Urceopolitan primacy, and upholds the Augustinian understanding of original sin in dialogue with the Audonian church. It is especially known for having canonized the proto-Protestant Ænglish reformer John Hess, whose teachings have significantly influenced the church. It is in full communion with the Old Hessian Church, the Insular Apostolic Church, and the Orthodox Church in Audonia.

Petrine Primacy
The church accepts that Saint Peter was the Prince of the Apostles, but rejects the association between Peter and the Urceopolitan see. It instead holds that the rightful successor to Peter is whichever Bishop is elected by the College of Bishops, preferring the title Catholicos over that of Pope. It further holds that, being elected by the College, the Petrine Pontiff exercises authority on behalf of the entire church and is its font of unity, but is ultimately subject to the while of the College gathered in ecumenical assembly. While not claiming to be the sole representative of the Catholic and Apostolic church, the Calixtine church teaches that its head is successor the Peter and font of unity insofar as he embodies the will of the bishops of LEVRIPC.
