The Paulicians self-identified as Christians, but much about the nature of their beliefs is disputed. Their beliefs prompted Christian critics to brand them as
Jews,
Muslims, and
Manichaeans but it is likely that their opponents employed these as pejorative appellations meant as terms of abuse, rather than as an accurate reflection of their beliefs. Examples of the disputed doctrines of the Paulicians include debate as to how they perceived the nature of God, the nature of Christ, and debate surrounding their worship rituals.
Sources There are few sources for the beliefs of the Paulicians except for the reports of opponents and some Paulician material preserved in the
History of the Paulician Heresy by
Petrus Siculus, comprising certain letters ascribed to
Sergius-Tychicus and, seemingly, a reworking of an account of their history composed by the Paulicians themselves. For some scholars, another major source is
The Key of Truth, a text claimed to be a manual of the medieval Paulician or
Tondrakian church in Armenia. This text was first identified by Armenian ecclesiastical authorities in 1837 while tracing a group of dissidents led by Hovhannes Vartabedian; British Orientalist Frederick Conybeare published a translation and edition of it in 1898. The manuscript transmission of the
Key is traced to the late 18th century, leading historians to raise doubts over its background, with some suggesting that its composition was influenced by
Protestant missionary activity in Armenia at that time.
Dualism Some scholars argue that the Paulician belief system was
dualistic, a cosmological system of twin, opposing deities; an Evil
demiurge who is author and lord of the present visible world; and a Good Spirit who is the God of the future world. Eighteenth century scholar
Johann Lorenz von Mosheim criticised the identification of Paulicians as Manichaeans, and although he agreed both sects were dualistic, he argued that the Paulicians differed on several points and undoubtedly rejected the doctrine of the
prophet Mani. The reports of Catholic missionaries working among the remaining Paulicians in the Balkans during the 16th–18th centuries do not reference dualist beliefs.
Christology Paulicians may have held several unorthodox beliefs about Jesus, including
nontrinitarianism (the belief that Jesus was not coeternal, coequal and indivisibly united in one being with God the Father and the Holy Spirit) and
docetism (the belief that Jesus only seemed to be human, and that his human form was an illusion). Nontrinitarian beliefs were held by
Arian Christians and many early Christian sects such as the
Adoptionists. The identification with nontrinitarianism sometimes led the Paulicians to be labeled as Arians by critics Conybeare also asserted that the movement were survivors of early
Adoptionist Christianity in Armenia rather than dualist or Gnostic sects. Conybeare's theory, part of a broader argument that Adoptionism represented the original form of Christianity that had subsequently been suppressed by the Catholic Church, met a skeptical reception at the time. In the 1960s, however,
Nina Garsoïan, in a comprehensive study of both Greek and Armenian sources, argued in support of a link to Adoptionism, and asserted that Paulicianism independently developed features of docetism and dualism. In a paper presented to the Unitarian Christian Alliance Conference in 2022, Atlanta Bible College adjunct professor Sean Finnegan argued that the Armenian sect which produced
The Key of Truth, while nontrinitarian, did not hold an Adoptionist Christology. Evidence against an Adoptionist Christology includes an affirmation of the virgin birth in chapter 23 of
The Key of Truth, as well as the use of the phrase "only-born" in
The Key of Truth chapters 2, 17, 21, and 22.
Rituals, practices and views of scripture The Paulicians were said to have used a different canon of sacred texts from the orthodox Christian bible. Byzantine scholars claimed that the sect accepted the four
Gospels (especially
of Luke); In the putatively Paulician or Tondrakian work
The Key of Truth, copied in the 18th century, the Old Testament, Baptism, Penance, and the Eucharist are all accepted. Early modern Catholic reports of the Paulicians remaining in the Balkans claimed that they were iconoclasts, rejecting the veneration of images and the Cross, that they used fire rather than water in baptism, and that they had a relatively simple conception of priesthood. The practice of baptism by fire by Paulicians in the region before their conversion to Catholicism is corroborated by the contemporary English diplomat
Paul Rycaut. ==Historiography==
