The Ecumenical Councils
🏛️ Thomistic Foundation
St. Thomas teaches that the Church's teaching authority (Magisterium) exercises Christ's own authority to bind and loose (Matthew 16:19). Ecumenical councils represent this authority in its most solemn form, guided by the Holy Spirit to preserve the deposit of faith (ST II-II, q. 1, a. 10).
The twenty-one Ecumenical Councils represent the Church's supreme exercise of teaching authority, addressing heresies, defining doctrine, and establishing discipline throughout history.
The First Seven Councils (325-787)
Recognized by both Eastern and Western Christianity, these councils established fundamental Christological and Trinitarian doctrine:
🔑 The Great Doctrinal Councils
- Nicaea I (325): Condemned Arianism, affirmed Christ's divinity
- Constantinople I (381): Completed Nicene Creed, affirmed Holy Spirit's divinity
- Ephesus (431): Condemned Nestorianism, defined Mary as Theotokos
- Chalcedon (451): Defined two natures of Christ in one Person
- Constantinople II (553): Condemned Three Chapters controversy
- Constantinople III (680-681): Condemned Monothelitism, affirmed two wills in Christ
- Nicaea II (787): Restored veneration of icons, condemned Iconoclasm
Medieval Councils (869-1517)
These councils addressed the Great Schism, conciliarism, and Church reform:
- Constantinople IV (869-870): Condemned Photius, affirmed papal primacy
- Lateran I-V: Church discipline and reform
- Lyon I & II: Attempted reunion with Eastern Churches
- Vienne (1311-1312): Suppressed Knights Templar
- Constance (1414-1418): Ended Great Schism
- Florence (1431-1445): Attempted Eastern reunion
- Lateran V (1512-1517): Last pre-Reformation council
Counter-Reformation and Modern Councils
- Trent (1545-1563): Counter-Reformation doctrinal definitions
- Vatican I (1869-1870): Papal infallibility and primacy
- Vatican II (1962-1965): Church renewal and engagement with modern world
📝 Study Questions
- How do the councils demonstrate the principle that the Church's doctrine develops but never changes?
- What is the relationship between papal primacy and conciliar authority?
- How do you respond to Orthodox objections that post-schism councils lack authority?
- What role did political pressures play in the councils, and how did the Holy Spirit preserve doctrinal truth?
Sacred Tradition
🏛️ Thomistic Foundation
St. Thomas distinguishes between divine tradition (handed down from the Apostles) and human traditions. Sacred Tradition is the living transmission of divine revelation, preserved by the Church under the guidance of the Holy Spirit (ST II-II, q. 1, a. 9).
Sacred Tradition, alongside Sacred Scripture, forms the single deposit of divine revelation. This is not merely human custom, but the living transmission of Christ's teaching through the Church.
Scripture and Tradition
🔑 Three Sources of Authority
- Sacred Scripture: Written Word of God
- Sacred Tradition: Unwritten apostolic teaching
- Magisterium: Teaching authority that interprets both
These three work together as one source of divine revelation, not three separate sources.
Examples of Sacred Tradition
- Canon of Scripture: The Bible's table of contents comes from Tradition
- Trinity: The word itself is not in Scripture
- Infant Baptism: Practiced from apostolic times
- Sunday Worship: Apostolic practice replacing Sabbath
- Marian Doctrines: Developed understanding of Mary's role
📝 Study Questions
- How do you respond to "sola scriptura" - Scripture alone?
- What is the difference between Sacred Tradition and human traditions?
- How does Tradition "develop" without changing?
- Why can't individual Christians interpret Scripture apart from the Church?
The Nature of Grace
🏛️ Thomistic Foundation
St. Thomas defines grace as "a participation in the divine life" (ST I-II, q. 110, a. 1). Grace is not merely God's favor, but an actual sharing in God's own nature, elevating human nature to a supernatural level capable of divine friendship.
Grace is the fundamental reality of Christian life - God's own life shared with rational creatures, enabling us to know and love God as He knows and loves Himself.
Types of Grace
🔑 Sanctifying vs. Actual Grace
- Sanctifying Grace: Permanent state of divine life in the soul
- Actual Grace: Temporary divine assistance for specific acts
Sanctifying grace makes us children of God; actual grace helps us act as children of God.
How Grace is Received
- Sacraments: Primary ordinary means of grace
- Prayer: Opens the soul to receive grace
- Good Works: Performed in grace, increase grace
- Scripture and Tradition: Instruments of grace
Grace and Free Will
Catholic teaching maintains that grace does not destroy free will but elevates and perfects it. We must cooperate with grace, though the initial movement toward God is always grace.
📝 Study Questions
- How is Catholic teaching on grace different from Protestant views?
- Can we merit grace? What does "merit" mean?
- How do you explain grace to someone who sees it as "unfair"?
- What is the relationship between grace and the virtues?
The Mass: Liturgical Theology
🏛️ Thomistic Foundation
St. Thomas teaches that the Eucharist contains the whole spiritual good of the Church - Christ Himself (ST III, q. 65, a. 3). The Mass is not merely symbolic but the actual re-presentation of Christ's sacrifice, making present the one sacrifice of Calvary.
The Mass is the source and summit of Christian life, where the Church both offers perfect worship to God and receives the fullness of divine grace.
The Sacrificial Nature
🔑 Four Elements of Sacrifice
- Priest: Christ, acting through the ordained minister
- Victim: Christ's Body and Blood, truly present
- Altar: The sacred table representing Calvary
- Action: The consecration making Christ present
Structure of the Mass
- Liturgy of the Word: God speaks to His people
- Liturgy of the Eucharist: The Church offers Christ to the Father
- Communion: The faithful receive Christ
- Dismissal: The Church is sent to live the Mass
Real Presence
Transubstantiation means that the entire substance of bread and wine is changed into the Body and Blood of Christ, while only the accidents (appearance) remain.
📝 Study Questions
- How do you explain transubstantiation using Aristotelian concepts?
- Why is the Mass a sacrifice, not just a meal?
- How does the Mass relate to Calvary?
- What is required for worthy reception of Communion?
Eschatology: The Last Things
🏛️ Thomistic Foundation
St. Thomas teaches that the resurrection of the body is necessary for the complete happiness of the human person, since humans are naturally composed of soul and body (ST Supplement, q. 75, a. 1). The soul alone in heaven is not the complete human person.
Catholic eschatology encompasses both individual destiny (particular judgment) and cosmic destiny (general judgment), maintaining the unity of soul and body in the final state.
Death and Particular Judgment
🔑 Three Possible Destinations
- Heaven: Perfect union with God for souls in perfect charity
- Purgatory: Purification for souls who die in grace but with venial sins
- Hell: Eternal separation from God for souls who die in mortal sin
The Resurrection of the Body
At the end of time, all the dead will rise with glorified bodies reunited to their souls. This resurrection is modeled on Christ's own resurrection.
- Identity: The same numerical body, but transformed
- Qualities: Impassible, subtle, agile, and clarified
- Purpose: Complete human happiness requires both soul and body
The Second Coming and Final Judgment
Christ will return in glory to judge the living and the dead, establishing His kingdom definitively and revealing the full meaning of salvation history.
📝 Study Questions
- How do you respond to claims that the resurrection is "unscientific"?
- What is the purpose of final judgment if particular judgment already occurred?
- How do you explain purgatory to Protestants who reject it?
- What does "glorified body" mean practically?
The Liturgical Year
🏛️ Thomistic Foundation
St. Thomas teaches that external acts of worship are necessary for humans, who are composed of soul and body. The liturgical year provides a rhythm of worship that engages the whole person in the mysteries of salvation (ST II-II, q. 81, a. 7).
The liturgical year is the Church's annual cycle of worship, making present the entire mystery of Christ from Incarnation to Ascension and the expectation of His return.
Major Seasons
🔑 The Church's Seasons
- Advent: Preparation for Christmas and Second Coming
- Christmas: Celebration of the Incarnation
- Lent: Preparation for Easter through penance
- Easter: Celebration of the Resurrection
- Ordinary Time: Growth in Christian living
Feast Days and Saints
- Solemnities: Highest rank celebrations (Christmas, Easter)
- Feasts: Important celebrations (Apostles, major saints)
- Memorials: Regular saint commemorations
Purpose of the Liturgical Year
The liturgical year allows Catholics to live with Christ throughout His earthly life, participating in His mysteries and growing in holiness through liturgical participation.
📝 Study Questions
- How does the liturgical year differ from the secular calendar?
- Why do Catholics honor saints instead of worshipping God alone?
- What is the relationship between liturgy and personal prayer?
- How do liturgical colors enhance worship?
Angels and the Spiritual Realm
🏛️ Thomistic Foundation
St. Thomas teaches that angels are pure spirits, created beings of great intelligence and will, who serve as intermediaries between God and material creation. They demonstrate that spiritual existence is possible and perfect (ST I, q. 50).
Angels are rational creatures created by God to worship Him and serve His plan of salvation. Their existence demonstrates the spiritual dimension of reality.
Nature of Angels
🔑 Angelic Properties
- Pure Spirits: No material bodies, though they can appear
- Created: Not eternal, but immortal once created
- Intelligent: Superior intellect to humans
- Free Will: Can choose good or evil (though fixed after testing)
The Nine Choirs
- First Hierarchy: Seraphim, Cherubim, Thrones - closest to God
- Second Hierarchy: Dominions, Powers, Virtues - govern creation
- Third Hierarchy: Principalities, Archangels, Angels - serve humans
Guardian Angels
Each person has a guardian angel assigned by God to protect and guide them throughout life. This is both doctrine and pious belief supported by Scripture and Tradition.
📝 Study Questions
- How do you respond to materialists who deny spiritual beings?
- What is the difference between angels and demons?
- How should Catholics relate to their guardian angels?
- Why did God create angels if He is sufficient in Himself?
Sacred Scripture and the Canon
🏛️ Thomistic Foundation
St. Thomas teaches that Scripture has God as its primary author, though human authors wrote according to their understanding. The literal sense intended by the human author is the foundation for all spiritual interpretation (ST I, q. 1, a. 10).
Sacred Scripture is the written Word of God, inspired by the Holy Spirit and interpreted authoritatively by the Church that discerned and preserved it.
Divine Inspiration
🔑 Levels of Biblical Interpretation
- Literal: What the human author intended to convey
- Allegorical: How events prefigure Christ
- Moral: How Scripture guides Christian living
- Anagogical: How Scripture points to eternal realities
The Formation of the Canon
The Catholic canon of 73 books was definitively established by the Church's authority, guided by criteria including apostolic origin, universal acceptance, and conformity to faith.
- Old Testament: 46 books including deuterocanonical works
- New Testament: 27 books definitively established by 397 AD
- Authority: The Church's discernment, not the books' self-attestation
Scripture and Tradition
Scripture emerges from Tradition and must be interpreted within Tradition. Private interpretation apart from the Church's guidance leads to error and division.
📝 Study Questions
- How do you defend the deuterocanonical books to Protestants?
- What is the relationship between inspiration and inerrancy?
- How do you explain apparent contradictions in Scripture?
- Why can't individuals interpret Scripture apart from the Church?
