Sanctification is not merely a "practical" and isolated doctrine but should permeate the whole horizon of theology: dogmatics, ethics, practics, as well as the sciences and the arts. The essays are collected under the twin convictions that theology can be sanctified and sanctifying. The whole of theology is inflected by holiness, and so theology should aim to share in God's sanctifying work. Sanctifying Theology contributes new possibilities in Wesleyan-holiness theology and explores their contribution to various Christian doctrines and contemporary issues. Written in honor of the work of Thomas Arthur Noble, the essays in this book are attentive to the streams of theology that have most influenced him: the fathers, the Wesleys, and the Torrances. Both constructive and exploratory, the topic of the essays cover, among other things, (1) consideration of how Wesleyan-holiness theologies contribute to ecumenical theological discussions, (2) readings of Wesleyan-holiness theology through the lens of the church fathers and the Torrances, and (3) explorations of how these conversations and sources might shape contemporary practical and ethical concerns. The essays work both for the Wesleyan tradition and from the Wesleyan tradition for the church catholic, showing how recent trajectories in Wesleyan-holiness theology might contribute to broader discussions.
