[Aquinasfan]

Scripture doesn't speak of Consubstantiation or Transubstantiation.

1 Corinthians 11

23For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread,
24and when he had given thanks, he broke it and said, "This is my body, which is for you; do this in remembrance of me."
25In the same way, after supper he took the cup, saying, "This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me."
26For whenever you eat this bread and drink this cup, you proclaim the Lord's death until he comes.
27Therefore, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord.
28A man ought to examine himself before he eats of the bread and drinks of the cup.
29For anyone who eats and drinks without recognizing the body of the Lord eats and drinks judgment on himself.
30That is why many among you are weak and sick, and a number of you have fallen asleep [died].

What in regard to these do you consider essential.

John 6:53

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.

[Titanites]

It bears worth repeating:

29For anyone who eats and drinks without recognizing the body of the Lord eats and drinks judgment on himself.

It can't be stated any plainer than that!

1 Corinthians 11:23 For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread,

24 and when he had given thanks, he broke it and said, "This is my body, which is for you; do this in remembrance of me."

25 In the same way, after supper he took the cup, saying, "This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me."

26 For whenever you eat this bread and drink this cup, you proclaim the Lord's death until he comes.

27 Therefore, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord.

28 A man ought to examine himself before he eats of the bread and drinks of the cup.

29 For anyone who eats and drinks without recognizing the body of the Lord eats and drinks judgment on himself.

30 That is why many among you are weak and sick, and a number of you have fallen asleep [died].

There is no speaking of any transformation here.
