Bishop Barron from Los Angeles explains this far better than I can in his Sunday Sermon Time to Test Your Faith: Catholics believe in the Transubstantiation. When the Priest raises the host up and says these words, “Take this all of you and eat of it for this is My Body” – the host (which is unleavened bread) actually becomes the body of Jesus. In a similar way, he raises the cup and says, “Take this all of you and drink from it for this is the Chalice of my Blood” for unless you eat my Body and drink My Blood you shall not have life in you.
Many people walk away from this and do not believe, but Catholics must believe this – it is “DOGMA” or mandatory teaching of the Catholic Church. Jesus did not mean this metaphorically as many Protestants and others believe. We have to remember who Jesus is the Son of God. He is All-Powerful and when He speaks He means what He says. How God can do these things we may never know, but He is Almighty and can do what He pleases.
Jesus actually wants to be with us and in us, deep into our hearts. He wants us to be a temple for Him to live in for all our life where He protects us and gives us life now and forever. He wants to abide in us and He wants us to abide in Him.

“Abide in me, and I will abide in you. Just as the branch cannot produce fruit by itself unless it abides in the vine, neither can you unless you abide in me. https://biblehub.com › john
