Against Heresies
Adversus Haereses — five books refuting gnostic systems and articulating the theology of recapitulation
Tradition: Pre-Nicene Christianity / Apostolic tradition
The most detailed early account of gnostic systems and the first systematic Christian theology of salvation history
Adversus Haereses is at once a heresiological encyclopaedia and a constructive theology. Book 1 describes the Valentinian and other gnostic systems in elaborate detail — it is the principal surviving source for many gnostic doctrines. Books 2–3 refute them by argument and by appeal to the apostolic tradition (the rule of faith, the succession of bishops, the four canonical Gospels). Books 4–5 develop Irenaeus's positive theology: the recapitulation (anakephalaiosis) of all things in Christ, the progressive pedagogy of God through the covenants, the goodness of material creation, and the final bodily resurrection. The work established the basic shape of orthodox Christian theology — creation, fall, incarnation, redemption, resurrection — that has persisted in all major traditions.

School Embodiments
Against Heresies established the basic architecture of orthodox Christian theology: one Creator God, the goodness of creation, the progressive covenantal economy, the Incarnation as recapitulation, bodily resurrection.
"The glory of God is a living man; and the life of man consists in beholding God." (IV.20.7)
Irenaeus's doctrine of apostolic succession — the chain of bishops guaranteeing authentic tradition — became the structural principle of Catholic ecclesiology.
"It is a matter of necessity that every Church should agree with this Church [Rome], on account of its pre-eminent authority." (III.3.2)
The theology of theosis (deification) articulated in Against Heresies V is the heart of Orthodox soteriology.
"Our Lord Jesus Christ … became what we are that He might make us what He is." (V, preface)
Irenaeus insists that creation reveals its Creator against the gnostic claim that the material world is a failed product of an ignorant deity.
"By means of the creation itself, the Word reveals God the Creator." (II.6.1)
While Irenaeus polemicises against gnostic misuse of Platonism, his own theology of divine simplicity and transcendence draws on the Platonic tradition he received through Middle-Platonic channels.
"God is simple, not compounded, without diverse members." (II.13.3)
Internal Tensions
Irenaeus's millennialism (literal thousand-year earthly reign of Christ, with abundant material blessings) sat uncomfortably with the later spiritualising tradition. His progressive theology of human maturation — Adam was an infant, not a perfect being — is in tension with the Augustinian doctrine of original perfection and catastrophic fall.
I. Time
Salvation history is Irenaeus's master category: God's pedagogy unfolds through progressive covenants (Adam, Noah, Moses, Christ). Time is linear, eschatological, and culminates in the recapitulation of all things in Christ.
Attributes
II. Space
One Creator, one creation: the gnostic multiplication of heavenly spaces (pleroma, aeons) is rejected. The cosmos is finite, three-dimensional, and the work of a single good God.
Attributes
III. Matter
Against gnostic dualism, matter is created ex nihilo by God, good, and destined for eschatological transformation. The Incarnation and bodily resurrection are the proof texts: God takes on flesh, and the flesh will rise.
Attributes
IV. Observer
The human being is body and soul together — not a divine spark trapped in evil matter. Agency is both human and divine: free will is real, but salvation depends on God's initiative in the Incarnation.
Attributes
V. Energy
Not technically treated. God sustains all creation in being; the covenantal economy is the framework within which all creaturely activity takes place.
Attributes
VI. Information
The rule of faith (regula fidei) is Irenaeus's primary informational concept: the apostolic teaching, handed down through the succession of bishops, is the guarantee of doctrinal truth against gnostic innovation.
