Tertullian — the North African Church Father (c. 155–220 CE) and creator of ecclesiastical Latin — appears throughout the depth-psychology corpus as a figure of charged psychological and theological significance. Jung deploys him most extensively in Psychological Types as a paradigmatic exemplar of the introverted thinking type taken to its most ferocious extreme: a man whose impassioned, one-sided intellect drove him to annihilate every position he had once championed, including his own orthodoxy. The phrase naturaliter Christiana — that the soul is naturally Christian — is attributed to Tertullian and used by Jung to interrogate the instinctual basis of religious conversion. Hillman appropriates Tertullian differently, discovering in the De anima and De Testimonio Animae a precedent for depth psychology's own method: letting the soul speak in its own native language rather than through external doctrine. Karen King's critical scholarship frames Tertullian as the architect of a polemical epistemology — the rule of faith and the chronological priority of truth over heresy — that shaped Western Christianity's suppression of Gnostic alternatives. Nietzsche and Sorabji invoke him for the theology of spectacle and the nascent concept of will, respectively. Across these readings, Tertullian functions as a node where psychology, theology, polemics, and the history of consciousness intersect.
brilliantly one-sided in his defence of a recognized truth, possessed of a matchless fighting spirit, a merciless opponent who saw victory only in the total annihilation of his adversary
Jung presents Tertullian as the supreme psychological type of fanatical one-sidedness, whose very intellectual passion compelled him to destroy every position — including those he had bled to defend.
, Psychological Types, 1921thesis
At another crucial time in psychological history, Tertullian did the same thing. He asked the soul to bear its own witness in its own language: I call in a new testimony, yes, one which is better known than all literature
Hillman reads Tertullian's appeal to the soul as a direct precedent for depth psychology's method of letting the psyche testify to itself rather than submitting to external doctrinal authority.

truth comes first and falsification afterward . . . Our teaching is not later; it is earlier than them all. In this lies the evidence of its truth, which everywhere has the first place.
King exposes the circular logic of Tertullian's rule of faith — that apostolic chronological priority proves truth while heresy's lateness proves falsity — as the structural foundation of anti-Gnostic polemics.

To know nothing against the Rule is to know everything.
King demonstrates how Tertullian's epistemological strategy — limiting scriptural inquiry to those sanctioned by hierarchical authority — functioned to suppress internal Christian pluralism rather than to refute an external enemy.

for conversion comes, and how far Tertullian was right in conceiving the soul as naturaliter Christiana
Jung uses Tertullian's formula that the soul is naturally Christian to interrogate the instinctual and typological foundations of religious experience and preferential psychological adaptation.

Tertullian himself was one of the few fathers not holding to this position, but in his usual brilliant way sums up, by the sentence quoted, his opponents' majority view. Tertullian (ibid.) held that 'to no one is heaven opened'
Hillman notes that Tertullian's theology of the afterlife — denying safe passage through Hades prior to the Last Judgment — constituted a minority patristic position that bore on the psychology of death and underworld transition.

His theology as distinguished from Tertullian's was essentially philosophical; it fitted neatly into the framework of Neoplatonic philosophy.
Jung contrasts Origen's Neoplatonic, philosophically harmonious theology with Tertullian's fiercely adversarial stance, defining two opposed psychological orientations within early Christian thought.

Tertullian On the Soul 21. 6 and 20. 5, recorded by Kahn, 'Discovering the Will', 250–1.
Sorabji cites Tertullian's De Anima as an early and significant source in the philosophical history of the concept of will, marking his place in the genealogy of voluntarism.

There are two standard translations of Tertullian's De Spectaculis.
Nietzsche's Genealogy of Morals invokes Tertullian's De Spectaculis as a defining document of ressentiment theology — the Christian fantasy of watching enemies suffer as eschatological spectacle.

According to Tertullian (Adversus Marcionem, I, cap. XIV; Migne, P. L., vol. 2, col. 262) the fish signifies 'the holier food.'
Jung cites Tertullian's Adversus Marcionem in the context of the fish as early Christian symbol of the Self, situating the patristic source within the astrological and archetypal argument of Aion.

Tertullian, PresHer 3 (trans. Greenslade, Early Latin Theology, 32). Tertullian's remark is a bit sarcastic in that he argues that they cannot really be the wisest
King notes the rhetorical and polemical character of Tertullian's remarks on those who seemed wise to his contemporaries, underscoring the strategic rather than purely theological function of his anti-heretical writing.

Tertullian On Patience 9. 4 (CC 1, pp. 309–10)
Sorabji locates Tertullian's On Patience within the patristic tradition of consolation literature that drew on Stoic frameworks for managing grief and emotion.
