The Eucharist is Jesus
The Eucharist is Jesus.
When Teresa of Avila heard some persons saying how great it would have been to have lived at the time when Christ walked the Earth, she used to laugh to herself. She wondered what more they wanted since in the Eucharist they had Him just as truly present as He was then. The only difference being the appearance. During his life most of the people ignored Jesus because when they looked at him they did not see God but only a man. Many people today do not spend time with Jesus in the Eucharist because when they look at it they see only bread and not God. In both cases, the Son of God is truly present.
1374 The mode of Christ's presence under the Eucharistic species is unique… 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 …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 only difference between the presence of Christ when he was with the disciples after the Resurrection and His presence in the Eucharist now, is the appearance. It is the same Jesus.
