Clergymen are regarded by their congregations as having the authority to influence church members and clergymen are expected to exert influence. Three types of clerical authority have been identified: charismatic, traditional, and legal-rational. The common assumption that people select power strategies that are consistent with their perceptions of their authority was tested in 50 Southern Baptist Convention pastors and 46 Roman Catholic priests. Also examined were the relationships between institutional factors such as denomination, individual differences such as variations in moral philosophy, and the power strategies used by clergymen. Subjects completed a 3-item measure of clergy authority, the Survey of Ethical Attitudes, a measure of power strategies, and a background questionnaire. The results indicated that authority type was significantly related to charismatic strategies and to legal-rational strategies, but not to traditional strategies. Denomination was significantly related to charismatic and legal-rational strategies, with Baptists scoring higher than Catholics in the use of both strategies. The relationship between denomination and traditional strategies was not significant. Ethics of Responsibility/Conscience was significantly related to charismatic and legal-rational strategies, but not to traditional strategies. These findings suggest that identifying one's power base is not equivalent to understanding one's power strategies. Future research on social influence should strive to distinguish power base from power strategy and measure both separately. (NB)
