Genuine and Integral Substance of the Eucharistic Mystery is the CDF formula linking a valid sacramental priesthood to the real Eucharistic sacrifice and therefore to classification as a Church in the proper sense.

The sacramental connection

Only a validly ordained priest or bishop can confect the Eucharist. Where Apostolic Succession in the Sacrament of Orders has not been preserved, a community lacks the ministerial priesthood required to make present Christ's Eucharistic sacrifice. Familiar liturgical words, vestments, an altar, or a strong doctrine of presence cannot supply invalid Orders.[1]

The CDF calls this absence a lack of the genuine and integral substance of the Eucharistic Mystery. The wording concerns the Catholic sacramental reality, not every form of thanksgiving, memorial, Scripture, prayer, or devotion to Christ found in non-Catholic worship. Those goods remain truly Christian where Baptism and faith are present.

Genuine and integral

Genuine identifies the Eucharist Christ instituted rather than a merely symbolic analogue. Integral indicates the sacrificial, sacramental, ministerial, and ecclesial whole, not only a theory about how Christ is present. The formula should not be shortened to Protestants have no worship or no relationship to Christ, claims the source does not teach.

Orders and ecclesial constitution

The absence of a valid episcopate and priesthood is not a missing ceremonial feature. It removes a Constitutive Element of a Particular Church. This is why communities born of the Reformation are called Ecclesial Communities rather than Churches in the Proper Sense, even when their members are validly baptized Christians.

Contrasting separated bodies

Separated Eastern Churches preserve bishops and priests in Apostolic Succession and celebrate a Valid Eucharist. Catholic doctrine accordingly calls them true Particular Churches and recognizes sacramental sharing in limited circumstances. Their lack of Full Communion does not invalidate Holy Orders or Eucharist.[2][3]

Anglican orders remain subject to the judgment of Apostolicae curae; most Protestant communities do not claim sacramental episcopal succession in the Catholic sense. An unusual individual line or ordination history requires competent examination and does not automatically change the corporate classification of an entire communion.

Eucharistic sharing and classification

Common Eucharistic celebration is both sacramental action and public expression of ecclesial unity. It ordinarily presupposes Full Communion. Canonical exceptions for Eastern Christians and, under stricter conditions, other baptized Christians respond to spiritual need; they do not announce that divisions or differences about Orders have ceased.[4]

Claims about the Eucharist depend upon the distinct questions treated by Validity of the Eucharist, Validity of Holy Orders, Apostolic Succession, and Sacramental Sharing. A doctrinal classification rests on the Magisterium, while the sacramental history of a concrete minister or body remains a separate historical and canonical inquiry.[5]
