A double major in Religion and Psychology (or major/minor or minor/major) can help make any religious professional more effective in counseling and any psychology professional better prepared to work with a religious clientele. Psychology of religion is a strategic field often neglected by scholars of both disciplines.
Some sample four year plans for combining the two fields in an undergraduate program at Carthage are laid out below, but any student planning on this double major should consult with his or her advisors to custom tailor an ideal program for that student.
