In this analysis of 7,443 parish clergy from six mainstream Protestant denominations, we have examined the clustering of religious beliefs. The survey provides a substantially more sophisticated array of theological belief than previous research, and covers sixteen theological content areas. Underlying these belief statements are a small number of factors which are, with minor exceptions, similar across denominations. The key factor which represents the major dimension of belief among Protestant clergy forms a continuum from a relatively literal to a relatively demythologized interpretation of the faith. We have conluded, therefore, that the structure of belief among mainstream Protestant clergy is unidimensional. We would further speculate that the most significant concomitants of belief would stem from this fact.
