The document discusses different types of Christian spirituality, including kataphatic and apophatic spirituality. Kataphatic spirituality, also called the "revealed God," uses symbols, images, and metaphors to know God through general and special revelation, representing a Western approach. Apophatic spirituality, also called "the mystery of God," emphasizes God's transcendence and hiddenness through a negative theology known as the "via negativa," representing a more Eastern approach. Both the mind and heart are discussed as ways of knowing and sensing God.
