While he is well known for his life-long fascination with the nature of religious experience, the colonial American pastor and theologian Jonathan Edwards is seldom associated with a specifically trinitarian spirituality. This study explores the central connection Edwards drew between his doctrines of religious experience and the Trinity: the person and work of the Holy Spirit. Edwards envisioned the Spirit's inter-trinitarian work as the affectionate bond of union between the Father and the Son, a work which, he argued, is reduplicated finitely in the work of redemption. Salvation is ultimately all about being drawn in love into the trinitarian life of the Godhead. This study takes us through the major regions of Edwards's theology, including his trinitarianism, his doctrine of the end for which God created the world, his Christology, and his doctrines of justification, sanctification, and glorification, to demonstrate the centrality of the Holy Spirit throughout his theology.
