This thesis examines the eucharistic theology of Bishop Jeremy Taylor (1613 – 1667), Bishop of Down and Connor. The introductory material surveys material written on Taylor over the 20th Century and the second chapter then lays out the development of eucharistic doctrine following the Reformation with a focus on the Church of England in order to locate Taylor’s thought. Two chapters offer an analysis and exegesis of Taylor’s important work The Real Presence and Spiritual of Christ in the Blessed Sacrament Proved Against the Doctrine of Transubstantiation, including an assessment of his understanding of transubstantiation. These are followed by a further chapter investigating Taylor’s writing on the eucharist in other devotional and apologetic works. Together this provides an assessment of Taylor’s understanding of eucharistic presence, an evaluation of his term ‘spiritual presence’ and additionally an exposition of his theology of eucharistic sacrifice. The analysis of Taylor’s writing concludes with a chapter exploring his use of patristic material and the influence of Platonism on his theology. Locating Taylor’s theology in the Augustinian framework of sacraments as signs Taylor’s description of eucharistic presence is then characterised using concepts from the 20th Century: transelementation, convaluation and transelementation. The thesis shows how these concepts can help to express Taylor’s thought by supplying new metaphysical lenses which were unavailable to him, freeing his ideas from the Aristotelian concepts of substance and accidents which dominated the Reformation era discussion of eucharistic presence. Taylor’s motif of spiritual presence is then reimagined using these descriptions of eucharistic presence to give a contemporary account of the eucharist.
