The first place I ever saw the phrase Occult Priestcraft was in Liber Null and Psychonaut, by Peter Carroll. Since all anyone seems to remember of Carroll is pieces of Liber MMM and a misunderstanding of his opposition to mysticism, and considering the recent debates here and the general clamoring for something new I thought now would be an especially auspicious to visit this portion of Carrolls work. Hopefully this will give people a wider and more accurate view of the chaos current, as well as provide some food for thought in relation to role of communities like key23.
Update: The second part is here.
