Natural Law Ethical Reasoning – Morality is not imposed on humanity or revealed by a deity or religious authority. Rather it is an integral part of our natural identity. Our moral responsibilities and rights arise from our nature (a reasoned teleological reflection on such) and our relationship to others. This vision offers a framework within which to conduct moral reasoning. Our motivation for virtue is a matter of our own integrity, following the logic of our very being.

Scholarly influences include – Alasdair MacIntyre, Max Scheler, Aristotle, Aquinas, Henry Veatch, John Finnis,

Narrative Theology -the idea that theology’s use of scripture should focus on a narrative representation rather than the development of a set of propositions reasoned from the texts themselves.  Narrative theology tries to focus its approach to theology to the meaning in the story and the ongoing claims of the various communities who comprise the people of the narrative.

Scholarly influences include – Henri de Lubac, Hans urs von Balthasar, George Lindbeck, Hans Frei, Stanley Hauerwas

Religious Naturalism – working from within the framework of a modest methodological naturalism to foster a spirituality informed by science and reason, theological realism, rooted in nature, affirming of human dignity, and dedicated to social justice and sustainability.

Scholarly influences include – Loyal Rue, Donald Crosby, Jerome Stone, Gordon Kaufman, Mordecai Kaplan, Thomas Berry

Mystical Panentheism – The affirmation that the divine/sacred pervades and interpenetrates every part of the universe and also extends beyond time and space. It includes an existential openness to the interconnectedness and unity of all being, the affirmation of the preciousness of all life, and the conviction that the sacred presence is both immanent and transcendent.

Scholarly influences include – Paul Tillich, Abraham Joshua Heschel, Alfred Whitehead, Katherine Keller, Thomas Nagel

Spiritual Ecology – a blending of convictions that include achieving justice and peace for all, respect for all living beings, reasoned reflection on human nature and its inherent ethical dimensions, and fostering an awareness of the sacred nature of all creation.
