From The Doctrine of the Sacraments in the Thirty-Nine Articles, an article in Churchman, the publication of the Church Society. By Roger Beckwith.

“The real presence is not in the elements, in such a way that those who receive the elements necessarily receive the body and blood of Christ. Rather, the real presence is in the administration of the sacrament, in such a way that those who with faith receive the sacrament receive Christ’s body and blood. Article 28 states it as follows:  ‘The Body of Christ is given, taken and eaten in the Supper only after a heavenly and spiritual manner. And the mean whereby the Body of Christ is received and eaten in the Supper is Faith.’ One may compare the language of the [1662] Catechism:  ‘the Body and Blood of Christ, which are verily and indeed taken and received by the faithful [Old English for believers] in the Lord’s Supper.’ One may also compare the language of Hooker:  ‘the real presence of Christ’s most blessed body and blood is not therefore to be sought for in the sacrament, but in the worthy receiver of the sacrament,’ that is, the one who receives with faith (Ecclesiastical Polity 5:67:6).”
