The mode of Christ's presence under the Eucharistic species is unique. It raises the Eucharist above all the sacraments as "the
perfection of the spiritual life and the end to which all sacraments tend." In the most blessed sacrament of the Eucharist "the
body and blood, together with the soul and divinity, of our Lord Jesus Christ and, therefore, the whole Christ is truly, really,
and substantially contained." "This presence is called 'real' - by which is not intended to exclude the other types of presence
as if they could not be 'real' too, but because it is presence in the fullest sense: that is to say, it is a substantial presence
by which Christ, God and man, makes himself wholly and entirely present."
