  • Spiritual Journey & World Religions

    Spiritual Journey is an adaptation of Option D: Responding to the Call of Jesus Christ and includes many elements of Option B: History of the Catholic Church in the Bishops’ Framework. It is designed to help students reflect on the presence of God in their lives by exploring the foundations of a fruitful spiritual journey, different prayer practices and images of God, the life stories of saints and spiritual figures, and ultimately, how to respond to God’s call in their lives. By reflective reading, viewing, and analysis of the stories of people seeking to better know themselves, God, and the meaning of their lives, students learn to see God in the people they meet and the choices they make. Students will also be introduced to a variety of situations and circumstances that contribute to their spiritual development using lecture, discussion, journaling, and film. The culminating final project asks students to design and create their own spiritual autobiography.

    World Religions (Online) follows Option E: Ecumenical and Inter-religious Issues in the Bishops’ Framework and begins with a discussion of Vatican II and the Church’s teaching on ecumenism, religious tolerance, and inter-faith dialogue recognizing non-Christian religions. The course then examines the eastern religions including Hinduism, Buddhism, Taoism, Confucianism, and Shinto. The course ends with the study of Judaism, Islam, and Christianity including other rites of Catholicism and Protestant faiths. This online section of World Religions is not UC-approved.

    Pre-requisite: Student must be a senior, have passed all required religious studies courses, and receive approval from the department chair and summer school principal.
