Adolf von Harnack (1851–1930), the towering German Protestant church historian, enters the depth-psychology corpus primarily as a methodological and theological reference point in discussions of Gnosticism, early Christianity, and the history of dogma. His signature formulation — Gnosticism as 'the acute Hellenization of Christianity' — functions across the corpus as both a productive thesis and a contested reduction: Karen L. King's sustained critical analysis in What Is Gnosticism? demonstrates how Harnack's kernel-and-husk model, his Protestant anti-Catholic polemics, and his Romantic idealism all shaped the very category of 'Gnosticism' that subsequent scholars inherited and naturalized. Harnack's effort to isolate a transhistorical essence of Christianity while relegating all doctrinal elaboration to dispensable 'husk' reflects the liberal Protestant project that Jung, too, had to reckon with; Jung cites Harnack's History of Dogma in Psychological Types, signaling the historian's structural importance for understanding Western religious development. Joseph Campbell draws on Harnack's multi-volume history as a documentary source for early Christian institutional history. The central tension in the corpus is between Harnack as enabler — whose historical method opened serious scholarly inquiry into heterodox Christianity — and Harnack as ideological architect of distortions regarding Judaism, Hellenism, and 'Oriental' religiosity that depth-psychological interpreters of religion have had to consciously dismantle.

Harnack famously described Gnosticism as 'the acute Hellenization of Christianity.' By this characterization he meant that Gnosticism 'was ruled in the main by the Greek spirit and determined by the interests and doctrines of the Greek philosophy of religion.'
King identifies Harnack's founding characterization of Gnosticism as the 'acute Hellenization of Christianity,' tracing how his erudition and this single formulation set the terms of the modern scholarly debate.
method allowed Harnack to insist repeatedly, not only that the essence of Christianity is neither Greek nor Jewish, but also that it is not historically bound... In the face of this powerful transhistorical essence, Harnack could hardly concede to any historical phenomenon, including Hellenism, a determinative influence on the Gospel.
King exposes the internal contradiction in Harnack's method: his kernel-and-husk model simultaneously acknowledged Hellenistic form and denied Hellenistic substance, protecting a transhistorical Christian essence from historical determination.
Harnack appears to have done with paganism what the polemicists did in the Christian construction of Judaism: appropriated all the positive characteristics of pagan thought... for true Christianity, while attributing all the negative characteristics... to his opponents, in this case Catholics.
King argues that Harnack reproduced a Protestant polemical structure, selectively appropriating positive Hellenistic elements for 'true' Christianity while projecting negative features onto Catholic opponents.
Harnack did not yet depict Gnosticism as a great evil or even entirely as heresy. On the contrary, he was able to recognize its positive contributions as well as its negative ones.
King notes the ambivalence in Harnack's early position, which recognized Gnosticism's structural analogy to Catholic Christianity rather than dismissing it outright as heresy.
The epoch-making significance of Gnosticism for the history of dogma must not be sought chiefly in the particular doctrines, but rather in the whole way in which Christianity is here conceived and transformed. The decisive thing is the conversion of the Gospel into a doctrine.
Harnack's own words, cited by King, define Gnosticism's significance as a total transformation of Christianity's mode of self-understanding rather than a deviation in specific doctrines.
Bousset was more definite than Harnack in distancing Jesus from Judaism... Poking at Harnack, Bousset quipped: 'If we wish to choose our termini following a famous example,' we should see in Gnosticism not the acute Hellenization of Christianity, but its 'acute Orientalizing.'
King maps the scholarly rivalry between Harnack and Bousset, showing how Bousset's 'acute Orientalizing' thesis explicitly contested Harnack's Hellenization framework as inadequate to account for Eastern religious influences.

Harnack maintains that by the end of the second century, Christianity had evolved from a series of communities with a living faith... into an institution comprised of interconnected congregations with a homogenous organizational structure, a 'law of doctrine,' and a liturgy.
Thielman summarizes Harnack's sociological-historical thesis that early Christianity's charismatic community life inevitably gave way to institutional structures, a view that shaped New Testament theology as a discipline.

Harnack gestured toward the historical Jesus and the experience of the first Christians as the sources of early Christian theology, not Oriental mysticism or Hellenistic mystery piety.
King explains that Harnack's rejection of Oriental influences on Christianity derived from his grounding of Christian origins in the historical Jesus and apostolic experience, insulating the Gospel from syncretistic contamination.

Harnack also believed that John, like Paul, Marcion, and Luther, had rejected Jewish legalism and emphasized freedom.
Thielman notes Harnack's interpretive pattern of aligning John, Paul, Marcion, and Luther as champions of evangelical freedom against Jewish legalism, revealing the Protestant-normative grid structuring his history.

The basic issue here is where the essence of Christianity is located: in the distinctive teaching of Jesus (Harnack) or in the tradition of the Church (Loisy).
King frames the Harnack-Loisy debate as a foundational dispute over the locus of Christian essence — apostolic teaching versus ecclesial tradition — that shaped twentieth-century theology and religious historiography.

Campbell draws on Harnack's History of Dogma as a primary documentary authority for early Christian institutional and schismatic history, deploying it as a reference text rather than a theoretical framework.

Jung's bibliography in Psychological Types includes Harnack's History of Dogma, confirming that Jung engaged with Harnack's monumental reconstruction of Christian doctrinal development as background for his own typological analyses.
The index entry placing Harnack at page 15 of Psychological Types confirms Jung's direct, if brief, textual engagement with Harnack's work within the context of his broader typological and religious-historical argument.
