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 the sacraments move. In the most Blessed Sacrament of the Eucharist - the Body and Blood, 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.
The Eucharistic presence of Christ begins at the moment of the consecration and endures as long as the Eucharistic species exist. Christ is present whole and entire in each of the species and whole and entire in each of their parts, in such a way that the breaking of the bread does not divide Christ.
It is highly fitting that Christ should have wanted to remain present to His Church in this unique way. Because Christ was about to take His departure from His own in his visible form, He wanted to give us His sacramental presence. Because He was about to offer Himself on the cross to save us, He wanted us to have the memorial of the love with which He loved us "to the end," even to the giving of His life. In His Eucharistic presence, He remains mysteriously in our midst as the one who loved us and gave Himself up for us, and He remains under signs that express and communicate this love.
The Church and the world have a great need for Eucharistic worship. Jesus awaits us in this sacrament of love. Let us not refuse the time to go to meet Him in adoration, in contemplation full of faith, and open to making amends for the serious offenses and crimes of the world. Let our adoration never cease.
Finally, by the Eucharistic celebration, we already unite ourselves with the heavenly liturgy and anticipate eternal life, when God will be all in all. In brief, the Eucharist is the sum and summary of our faith: Our way of thinking is attuned to the Eucharist, and the Eucharist in turn confirms our way of thinking.
