How would you define theology, psychology?

Drawing from your own experiences and knowledge as well as any research you wish to do, how would you define theology, psychology? What does each discipline offer to human knowledge and understanding? Are the two disciplines at odds in any way? Do they complement each other? Are you drawn to either discipline as you figure out the meaning of your own life and vocation? Write a paragraph or two as you contemplate some of these questions. Your writing can be in the form of a personal journal entry, which is usually more informal and more personal than essay writing. (about 300 words)
