He is also present in the Eucharist in the tabernacle in the Church:
John 6: 52-59Then the Jews began to argue sharply among themselves, "How can this man give us his flesh to eat?" [not interpreting this metaphorically]
Jesus said to them, "I tell you the truth, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day. For my flesh is real food and my blood is real drink. Whoever eats my flesh and drinks my blood remains in me, and I in him. Just as the living Father sent me and I live because of the Father, so the one who feeds on me will live because of me. This is the bread that came down from heaven. Your forefathers ate manna and died, but he who feeds on this bread will live forever."
On hearing it, many of his disciples said, "This is a hard teaching. Who can accept it?" [Why would this be a "hard saying" if Jesus was speaking metaphorically?]
Aware that his disciples were grumbling about this, Jesus said to them, "Does this offend you?..." [Not, "Oh sorry! I meant that metaphorically!] He went on to say, "This is why I told you that no one can come to me unless the Father has enabled him." From this time many of his disciples turned back and no longer followed him. [Does Jesus say, "Hey wait, you misunderstood! I was speaking metaphorically!" ] "You do not want to leave too, do you?" Jesus asked the Twelve.
Simon Peter answered him, "Lord, to whom shall we go? You have the words of eternal life. We believe and know that you are the Holy One of God." [Peter answers with a statement of trust and belief. Note that he doesn't say, "Oh yeah, you were speaking metaphorically."]
