The Importance of Talking to the Deceased

The Old Testament contains strong prohibitions on necromancy, but these look like ceremonial precepts to direct the Israelites away from Canaanite practices. The New Testament also doesn't forbid contact with spirits. Father Castle is doing it with the consent of his superiors and he seems to employ the principles we've discussed. So I agree with the theologian they consulted. It looks like this is an acceptable practice that is not contrary to church teaching.
