Course Offerings

  • Applied Spirituality

    Drawing on the knowledge of prayer, Catholic practices, morality, history and beliefs that students have gained during previous years of theology, this capstone class is designed to aid students in developing spiritual practices, within the context of a Lasallian Roman Catholic school. The emphasis in the class is on spiritual growth, deeper understanding of self, God and others and the vocation to love.
  • Bioethics

    Bioethics is an exploration of modern technologies related to medicine and biology and how they affect the dignity of the human person. The course focuses on what it means to be human from the biological, philosophical and spiritual perspectives. Foundational scientific understandings including the Big Bang Theory, evolution, embryology, stem cell research, fertility, end of life issues, and current issues in the news are studied. Finally, the moral, legal and political implications of controversial technologies are examined through the lense of the Catholic Church’s teachings on human dignity.
  • Comparative Religions

    This course is a comparative study of the major world religions including Hinduism, Buddhism, Confucianism, Taoism, Judaism, Islam, and Native American Spirituality. Under the mandate of Vatican II, this class seeks to discover "what is true and holy in these religions." Experiential and cultural emphases invite both empathy and understanding of people of the world.
  • Lasallian Service Learning CP

    This class will offer students the opportunity, through service learning, to explore the practical dimensions of Catholic social justice in the local community and reflect on the Christian concept of servant leadership. Students will learn skills and content through research, practice, literature, discussion, and action by working directly with the marginalized population in the Sheridan area. They will also have the opportunity to experience approximately thirty-five hours of direct service within Sheridan School District classrooms. In addition to direct service, each presentation and project will integrate the five stages of service: Investigation, Preparation, Action, Reflection and Demonstration as well as the Catholic Lasallian core principle of Concern for the Poor and Social Justice.
  • Morality - Human Nature

    This course is designed to help students explore what it means to be happy  through the fulfillment of our human nature and by choosing to do the good. Specifically, it will build on the fundamental principles of truth learned in Reasons for the Faith A in order to understand the universal nature of morality. Students will understand the roles of freedom and conscience and the steps for making a moral decision. In addition, the 10 Commandments and the Beatitudes will be examined to help students understand their moral responsibilities.
  • Morality - Nature of Love

    This course will examine the definition and nature of love as it is revealed in the Trinity and embraced as part of human nature. Students will discover that fulfillment lies in the gift of self and how they choose to apply this to their lives. John Paul II’s Theology of the Body and other Catholic teachings, will be used to examine the implications for friendship, dating, marriage, and family life. Finally, students will examine the basics of human sexuality and the challenges our culture faces.
  • New Testament

    The study of salvation history reaches its fullness in the life and teachings of Jesus Christ, as revealed in the Gospels, letters of St. Paul and witnesses of the early Church. The New Testament will be studied through the historical, cultural, political, and theological background of the first century world, and in addition, the foundation and early tradition of the Church will be studied. Students will be challenged to experience Christ’s Paschal Mystery as an invitation to love God, others, and self.
  • Old Testament

    Students will discover God’s plan of salvation and His covenant plan through reading the Old Testament Scriptures.  They will also discover how the Old Testament Scriptures prepare and foretell the coming of Jesus Christ and the Church. This class will also include information about the life of our founder, St. John Baptist de la Salle and the legacy he left. 
  • Reasons for the Faith A

    This course is designed to help students understand the importance of recognizing and embracing the good as it is found in truth, in a world filled with relativism.  Through an exploration of logical thinking, classical philosophy, the question of what faith is, the many ways to prove things, and the Catholic approach to understanding God, students will work to comprehend these realities in their own lives.  Ultimately, the students will be encouraged to explore why a relationship with God is good for us.
  • Reasons for the Faith B

    This course continues from the conclusion of Reasons for the Faith A CP (“It is reasonable that God exists”) to lay the foundations for faith in God, specifically through the Incarnation, Jesus Christ.  This course invites students to consider how the living Christ has acted in history to save us and continues to act in the world to save us today through the Catholic Church, namely the Sacraments. Because the Nicene Creed is a summary of beliefs that Christians hold in common about faith, the Creed provides the outline for the course.
  • Social Justice & Peace

    Catholic Social Teaching is based on the life and works of Jesus Christ. This course will examine issues of social justice, including economic equality, immigration, race, ecology, war and violence through the lens of Catholic Social teaching. Through civil discourse, students will speak out on social matters which threaten the human dignity of all persons made in God’s image and likeness.
