Eucharistic Species

In Eucharistic doctrine, species means the sensible appearances or properties of bread and wine: what can be seen, touched, and tasted. At the consecration, the whole substance of the bread is changed into Christ's Body and the whole substance of the wine into his Blood, while these appearances remain. The Church fittingly calls this change transubstantiation.^[1]

Before consecration, the matter of the sacrament is true wheat bread and natural grape wine. After consecration, it is no longer accurate to speak as though ordinary bread and wine remained alongside Christ. The living and glorious Christ is truly, really, and substantially present—Body, Blood, Soul, and Divinity—under the sacramental species.^[2]

Christ is present whole and entire under each species and whole and entire in every part of either species. Breaking a consecrated host does not divide Christ, and receiving only the consecrated host does not mean receiving only his Body apart from his Blood, Soul, or Divinity. The same doctrine governs reception from the chalice alone when that is lawfully done.

Communion under both kinds gives a fuller expression to the sign of the Eucharistic banquet and Christ's command concerning the cup, but it does not give more Christ or more sacramental grace merely by quantity. The Church can regulate when and how Communion under both kinds is offered while preserving the full sufficiency of Communion under either species.^[3]

Christ's Eucharistic presence endures as long as the species subsist. Consecrated hosts are therefore reserved and adored, the Precious Blood is consumed, and visible particles or drops are treated with reverence. Once the species no longer exist as the appearances of bread or wine, the sacramental presence ceases.

This teaching joins exact doctrine to practical care. Sacred vessels are purified, hosts are protected from profanation, and the faithful adore the sacrament not because of material appearance but because Christ himself remains present under it.
