Latin / North African Patristic Tradition

Quintus Septimius Florens Tertullianus was the founder of Western Latin theological terminology. In works like *Apology*, *Adversus Praxean*, and *De Praescriptione Haereticorum*, he coined the terms 'Trinitas' (Trinity), 'substantia' (substance), and 'persona' (person), while famously asking 'What has Athens to do with Jerusalem?'.

Thascius Caecilius Cyprianus was bishop of Carthage during the Decian and Valerian persecutions. In his defining treatise *On the Unity of the Church* (De Ecclesiae Catholicae Unitate), he argued that the episcopate is a joint college holding unity in undivided shares, famously stating: 'He can no longer have God for his Father who has not the Church for his mother'.

Sophronius Eusebius Hieronymus was the premier Latin biblical scholar and translator who produced the Latin Vulgate Bible, breaking with tradition to translate the Old Testament directly from the 'Hebrew truth' (Hebraica veritas) rather than the Greek Septuagint, and authoring extensive historical and literal biblical commentaries.

Aurelius Augustinus was the monumental architect of Western Christian theology. In foundational works like *Confessions*, *On the Trinity* (De Trinitate), *The City of God* (De Civitate Dei), and anti-Pelagian treatises, he articulated the doctrines of original sin, sovereign irresistible grace, psychological Trinitarian analogies, and the distinction between the visible church and the elect invisible church.

Leo I was Pope of Rome whose dogmatic letter *Tome of Leo* (Epistle 28 to Flavian) defined orthodox Christology for the Council of Chalcedon (451 AD): 'Each form does what is proper to it with the cooperation of the other', acclaimed by the council fathers with the shout: 'Peter has spoken through Leo!'.

Donatism was a bitter North African schism sparked by the Diocletianic persecution (303–305 AD), asserting that ministers who surrendered sacred Scriptures to Roman authorities (traditores) forfeited their orders, and that sacraments (especially baptism and ordination) administered by unworthy clergy were invalid, rebaptizing all who entered their communion.

The Roman Catholic Church is the largest Christian communion (over 1.3 billion members), recognizing the Pope (Bishop of Rome and Successor of Peter) as the supreme visible head and pastor of the universal Church on earth, acknowledging 21 ecumenical councils, seven sacraments, the sacrificial offering of the Eucharist, and the integration of faith and reason.

Anselm of Canterbury was the Italian-born Archbishop of Canterbury widely regarded as the Father of Scholasticism. He formulated the celebrated program of Christian intellectual inquiry: 'faith seeking understanding' (*fides quaerens intellectum*), devised the Ontological Argument for God's existence in the *Proslogion*, and formulated the Satisfaction Theory of the Atonement in *Cur Deus Homo* (Why God Became Man).
