What's your starting point?

I sometimes point out to my students that Protestant primers of theology commonly have a first chapter on revelation or the Bible, whereas their Orthodox counterparts often start with a treatment of mystery. The differences here no doubt relate to the various ways that theologians view God-knowledge. Whereas some Christians may be suspicious of the term “mystery," a renowned theologian like Vladimir Lossky can make the following claim: “In a certain sense all theology is mystical, inasmuch as it shows forth the divine mystery.” For such an assertion to make sense, we need to recognize a certain epistemological sensibility present here involving how we form and develop God-knowledge.—Pentecostalism as a Christian Mystical Tradition, pages 47–48
