My goodness, Kate - get a life! Personality tests have been so useful to build my self-awareness, to understand my strengths and weaknesses, what I need to work on and what areas of my life I need to develop. To be honest, you can trace many things back to an occultic source if you're looking, but I'm so glad God takes what is 'wordly' and turns these things around for His glory; that's what I think has happened with the Enneagram and Myers Briggs. They are a blessing to the church if used appropriately. It often seems to me that, because of your recent New Age background, you see the enemy all around when God has actually redeemed many things for His sake.
