Introduction

  • Instructor: Father Romanus Cesario
  • Institution: St. John Seminary, Brighton, Massachusetts
  • Course Title: Elements of Moral Theology
  • Lecture Context: Third of six lectures, focusing on Natural Law

What is Catholic Moral Theology?

  • Located within the saving instruction of God communicated to the Church
  • Discusses the happy life and the Christian way of life
  • Differs from moral philosophy and secular ethics
  • Bound by divine revelation and aims to present the big picture of human life in God's plan

Key Themes from Previous Lectures

Lecture 1

  • Introduction to the program and specificities of Catholic moral theology
  • Saving instruction covers both faith and morals

Lecture 2

  • Anthropology: Imago Dei (Image of God)
    • Humans made in God's image inherently
    • Imaging is inherent and free—reflects God's imprint on us
    • Free will is a divine gift, and both divine initiative and human response are gifts
  • Imago Dei leads to Imago Gratia (Image of Grace)
    • Living by divine grace leads to conformity with Christ and the cross

Natural Law and Moral Theology

Contextual Foundation

  • Man set between God as origin and God as end (beatitude)
  • God's end for us is ultimately Himself, to share in the Trinity's life
  • Catholic moral theology involves understanding both divine origins and ultimate ends

Theological Perspective

  • Based on Thomas Aquinas' work
  • Natural Law: Participation of rational creatures in the eternal law
  • Eternal Law: God’s way of governing creation, reflecting divine plan or design
  • Disputes over whether natural law involves divine will or knowledge

Key Examples in Natural Law

  • Life: Protecting, preserving, and flourishing biological life
  • Human Sexuality: Male and female coupling for procreation
  • Truth-telling: Essential for rational communication and friendship

Contemporary Challenges

  • Modern emphasis on autonomy conflicts with the notion of divine pattern shaping human behavior
  • Importance of understanding natural law in the context of divine knowledge and governance

Church Teachings and Natural Law

  • Addressed by Pope John Paul II in "Veritas Splendor"
  • Natural law as part of the Church's moral teaching patrimony
  • Debate on natural law persistence post-Vatican II

Conclusion

  • Natural Law viewed as a guide to living a godly life in alignment with how God knows the world to be
  • Teleology: Focus on ends that perfect the human person
  • Encouragement for further study and understanding of natural law and its implications

Suggested Readings

  • Book: "The Splendor of the Truth: Veritas Splendor and the Renewal of Moral Theology" (Edited by Father Romanus Cesario and Father Augustin DeNoia)

Note: This summary captures the essence of the lecture on natural law and its role in Catholic moral theology, focusing on the interplay between divine origin, eternal law, and human conduct.
