In Theological Hermeneutics in the Classical Pentecostal Tradition: A Typological Account, L. William Oliverio Jr. accounts for the development of Classical Pentecostal theology, as theological hermeneutics, through four types: the original Classical Pentecostal hermeneutic, the Evangelical-Pentecostal hermeneutic, the contextual-Pentecostal hermeneutic, and the ecumenical-Pentecostal hermeneutic. Oliverio gives special attention to key figures in shaping Pentecostal theology and the underlying philosophical assumptions which informed their theological interpretations of reality. The text concludes with a philosophical basis for future Pentecostal theological hermeneutics within the contours of a hermeneutical realism that affirms both the hermeneutical nature of all theology and the implicit affirmation of realism within theological accounts.
