. "Hence it also follows that Christ is so contained, whole and entire, 

under either species that, as under the species of bread are contained not 

only the body but also the blood and Christ entire, so in like manner under 

the species of wine are truly contained not only the blood, but also the 

body and Christ entire. These are matters on which the faithful cannot 

entertain a doubt. Wisely, however, was it ordained that two distinct 

consecrations should take place. They represent in a more lively manner the 

Passion of Our Lord, in which His blood was separated from His body; and 

hence in the form of consecration we commemorate the shedding of His blood. 

Again, since the Sacrament is to be used by us as the food and nourishment 

of our souls, it was most appropriate that it should be instituted as food 

and drink, two things which obviously constitute the complete sustenance of 

man.

"Nor should it be forgotten that Christ is, whole and entire. contained not 

only under either species, but also in each particle of either species. 

'Each,' says St. Augustine, 'receives Christ the Lord, and He is entire in 

each portion. He is not diminished by being given to many, but gives 

Himself whole and entire to each' (cited in Gratian, 'De consecratione,' 

dist. ). This is also an obvious inference from the narrative of the 

Evangelists. It is not to be supposed that Our Lord consecrated the bread 

used at the Last Supper in separate parts, applying the form particularly 

to each, but that all the bread then used for the sacred mysteries was 

consecrated at the same time and with the same form, and in a quantity 

sufficient for all the Apostles. That the consecration of the chalice was 

performed in this manner, is clear from these words of the Saviour: 'Take 

and divide it among you' (Luke, xxii, )" ("Roman Catechism," "The 

Eucharist," -).

. "Those who receive this Sacrament piously and fervently must, without 

any doubt, so receive the Son of God into their souls as to be united as 

living members to His Body. For it is written, 'He that eateth Me, the same 

also shall live by Me.' And again: 'The bread which I will give is My flesh 

for the life of the world' (John, vi. ). . . . For the Eucharist is the 

end of all the Sacraments, and the symbol of unity and brotherhood in the 

Church" ("Roman Catechism," "loc. cit.," ).
