1. _In the sacrament of the Eucharist_, _after the consecration of the bread and wine_, _our Lord Jesus Christ_, _true God and true man_, _is_, _truly and really and substantially_, _contained_, _under the species of those sensible objects_: _so that_, _immediately after consecration_, _the true body and the true blood of our Lord_, _together with his soul and divinity_, _exist under the species of bread and wine_: _for_, _by the very force of the words themselves_, _the blood exists under the species of the wine_; _and the body_, _under the species of the bread_. _But_, _furthermore_, _by virtue of that natural connection and concomitance_, _through which the parts of the Lord_, _after his resurrection from the dead_, _are mutually joined together_, _the body exists under the species of the wine_, _the blood exists under the species of the bread_, _and the soul exists under the species both of the bread and the wine_. _The divinity_, _moreover_, _on account of its admirable hypostatic union with the body and the soul_, _similarly exists alike under each species_. _Wherefore_, _under each species and under both species_, _so much as even the whole is contained_. _For the entire Christ exists both under the species of bread_, _and under each particle of that species_: _and the entire Christ exists_, _both under the species of wine_, _and under all the particles of that species_. _Hence_, _through the consecration of the bread and wine_, _there takes place a conversion of the whole substance of the bread into the substance of the body of our Lord Christ_, _and of the whole substance of the wine into the substance of his blood_: _which conversion is properly and conveniently denominated Transubstantiation_. 2. _All the faithful are bound to offer to the Eucharist that same adoration of Latria_, _which is paid to the Deity_: _for such adoration rests upon the belief_, _that in that sacrament there is substantially present the filial God_, _concerning whom the Father pronounced_; _Let all the angels of God worship him_. _And_, _analogously_, _in point of beneficial efficacy_, _the Eucharist_, _being the identical sacrifice which Christ __offered upon the cross_, _must be deemed a true propitiatory sacrifice_, _making satisfaction_, _each time that it is offered_, _not only for the living_, _but likewise for the dead in the Lord who have not as yet been fully purified_. {11a} II. Let us now hear Scripture with respect to this same holy sacrament.
