Anglican from Roman Church doctrine. The Articles declared that "Transubstantiation (or the change of the substance of Bread and Wine) in the Supper of the Lord, cannot be proved by holy Writ; but is repugnant to the plain words of Scripture, overthroweth the nature of a Sacrament, and hath given occasion to many superstitions." The Elizabethan Settlement accepted the Real Presence of Christ in the Sacrament, but refused to define it, preferring to leave it a mystery. Indeed, for many years it was illegal in Britain to hold public office whilst believing in transubstantiation, as under the Test Act of 1673. Archbishop John Tillotson decried the "real barbarousness of this Sacrament and Rite of our Religion", considering it a great impiety to believe that people who attend Holy Communion "verily eat and drink the natural flesh and blood of Christ. And what can any man do more unworthily towards a Friend? How can he possibly use him more barbarously, than to feast upon his living flesh and blood?" (Discourse against Transubstantiation, London 1684, 35). In the Church of England today, clergy are required to assent that the 39 Articles have borne witness to the Christian faith. The Eucharistic teaching labeled "receptionism", defined by Claude Beaufort Moss as "the theory that we receive the Body and Blood of Christ when we receive the bread and wine, but they are not identified with the bread and wine which are not changed", was commonly held by 16th and 17th-century Anglican theologians. It was characteristic of 17th century thought to "insist on the real presence of Christ in the Eucharist, but to profess agnosticism concerning the manner of the presence". It remained "the dominant theological position in the Church of England until the Oxford Movement in the early nineteenth century, with varying degrees of emphasis". Importantly, it is "a doctrine of the real presence" but one which "relates the presence primarily to the worthy receiver rather than to the elements of bread and wine". Anglicans generally consider no teaching binding that, according to the Articles, "cannot be found in Holy Scripture or proved thereby", and are not unanimous in the interpretation of such passages as John 6 and 1 Corinthians 11, although all Anglicans affirm a view of the real presence of Christ in the Eucharist: some Anglicans (especially Anglo-Catholics and some other High Church Anglicans) hold to a belief in the corporeal presence
