Paideia: Instruction of the Lord

And these words which I command you today shall be in your heart. You shall teach them diligently to your children, and shall talk of them when you sit in your house, when you walk by the way, when you lie down, and when you rise up. Deuteronomy 6:6-7

Fathers, do not provoke your children to anger, but bring them up in the discipline and instruction of the Lord. Ephesians 6:4

In Ephesians 6:4, the Apostle Paul commands Fathers (πατέρα) to bring up their children in “discipline” (παιδείᾳ) and “Instruction in the Lord” (νουθεσίᾳ κυρίου). Fathers are commanded to use “paideia,” an enculturation process tied to “instruction in the Lord.” Paul commissioned the Body of Christ to disciple their children through a curriculum focusing on our Creator and His creation, work, and Church.

CogNatE Natural Philosophy began to partner with Southeastern University (a Christian, regionally accredited university in Lakeland, Florida) to offer a complete Natural Philosophy curriculum grounded in the Classical Christian Education Model. Our programs in Natural Philosophy are designed for college and dual-enrolled high school students. Courses start in the Fall of 2024.

Classical Christian Education Model


Our Natural PhiloSophy begins with The Trivium (i.e., Grammar, Logic, and Rhetoric) as a foundation to employ classical grammar and logic to make effective and persuasive arguments and presentations. 

Classica (Greek I) 

Explores the foundations of classical Attic Greek, the language of renowned philosophers, playwrights, and historians. Students will investigate the Greek alphabet, essential grammar rules, and a foundational vocabulary. Reading, interpreting, and writing skills, focusing on authentic ancient Greek texts are emphasized. 

Classica (Greek II) 

Delves deeper into the Greek language and literature and aims to further enhance linguistic skills, broaden vocabulary, and deepen comprehension of complex ancient Greek texts.

Classica (Latin I) 

Explores the foundations of classical Latin—the language of the Roman Empire. This course investigates ancient Rome’s linguistic, literary, and historical legacy. Students will acquire essential language skills, delve into Roman culture, and consider Latin literature.

Classica (Latin II) 

Dives deeper into Latin syntax, expanding vocabulary, and introducing more complex literary texts. Students will enhance their proficiency in reading, translating, and appreciating classical Latin literature through rigorous grammar study, textual analysis, and engagement with authentic Latin writings.

(Logic and Dialectic) 

Investigates classical logic, a foundational branch of mathematics, within the framework of the Christian worldview. This course explores the principles of reasoning and argumentation through propositional and first-order logic for analyzing and constructing logical arguments. 

Rhetorica (Rhetoric) 

Considers the art of classical rhetoric to analyze, practice, and appreciate the enduring principles of persuasive communication. Students will develop the confidence and skill to communicate persuasively in various personal, academic, and professional contexts.


Next, our Natural PhiloSophy continues the exploration of Number in The Quadrivium (i.e., ArithMetica, GeoMetria, Musica, and AstroNomia).

(Arithmetic: Number in Abstraction) 

Founded on mathematical axiom systems, this course explores number theory and how and why arithmetical properties and operations work. 

GeoMetria I
(Geometry I: Number in Space

Guided by logic within axiom systems, this course considers Plane Geometry through synthetic, metric, analytic, locus, and other perspectives. 

GeoMetria II
(Geometry II: Number in Space

Builds to 3-dimensional geometry and provides brief introductions to neutral and non-Euclidean geometries. 

(Music: Number in Time

Investigates the intersection of Physics and musicology course. This course considers the underlying Physics principles that shape the sonic landscapes we experience. 

(Astronomy: Number in Space and Time)

Considers man’s study of the heavens and their motions through geocentric and heliocentric models, planetary motion, the discovery of moons and other celestial objects, and the laws of planetary motion.


Finally, our program explores Moral PhiloSophy (Wisdom from God’s revelation in Scripture), Natural Philosophy (Wisdom from God’s revelation in His Creation), and OrthoDoxia (WisdomTo Rightly Praise”) as the apex of Classical Christian Education Model

(Literature: The Western Canon)

Delves into a literary masterpiece, fostering an appreciation for the Western Canon and its enduring contributions. Scholarly inquiry, critical discussion, and creative engagement reveal the text’s role in Western literary and intellectual traditions.

Algebra I

Considers numbers and operations; the Cartesian coordinate system; transformations of rigid figures; linear equations and inequalities; relations and functions; direct and indirect variation; polynomials; rational functions; and data analysis and probability. 

Algebra II

Investigates functions and their inverses; quadratic functions; sequences and series; systems of equations and inequalities; polynomials and operations; Fundamental Theorem of Algebra; radical functions; exponential and logarithmic functions; and transformations of functions. 

Scriptura I (Scripture I)

Examines the Old Testament, through the text, its transmission, and its written languages. Through discussions and critical analyses, appreciation is built for the Old Testament as a foundational document in the Judeo-Christian tradition.

Scriptura II (Scripture II)

Considers the New Testament, through the text, its transmission, and its written languages. Through discussions and critical analyses, appreciation is built for the New Testament as a foundational document in the Judeo-Christian tradition.

TheoLogica I
(Historical Theology I)

Engages primary texts, historical contexts, and theological debates regarding the diverse intellectual currents that shaped early Christian theology. Through critical analysis and thoughtful discussion, appreciation for the enduring impact of theological giants on the Christian tradition is built.

TheoLogica II
(Historical Theology II)

Explores 15th- and 16th-century theological perspectives and transformations within the Protestant and Catholic traditions and their enduring impact on Christian thought and practice. Through critical analysis of primary texts and historical contexts, this course investigates the theological currents that shaped this transformative period.

PhiloSophiae I
(Introductory Philosophy)

Examines the intricate relationship between theology and philosophy, tracing the development of Christian thought from its early roots to its contemporary expressions. This course examines the philosophical inquiries of influential thinkers shaping Christian tradition and applies these insights to contemporary theological issues.

PhiloSophiae II (Epistemology)

Grapples with foundational questions of knowledge and belief from a Classical Christian perspective. Through careful analysis of primary texts, philosophical frameworks, and historical contexts, this course explores how influential thinkers have contributed to the ongoing conversation about the intersection of faith and reason in Christian epistemology.
