Christ in present fully in either consecrated species, so long as either species remains in appearance, respectively, apparent bread or apparent wine. Body, blood, soul, and divinity of Christ is present either in the bread or in the wine. This is why a communion in bread alone or in wine alone is possible, and in fact for many centuries was the norm.

So it follows that so long as one of the two species remains what it appears to be, the entire Christ is present.

1 Corinthians 11

For I received from the Lord what I also delivered to you, that the Lord Jesus on the night when he was betrayed took bread, 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." In the same way also he took the cup, after supper, saying, "This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me." For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes.

Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty concerning the body and blood of the Lord. Let a person examine himself, then, and so eat of the bread and drink of the cup. For anyone who eats and drinks without discerning the body eats and drinks judgment on himself. That is why many of you are weak and ill, and some have died. But if we judged ourselves truly, we would not be judged. But when we are judged by the Lord, we are disciplined so that we may not be condemned along with the world.

Jesus gave BOTH the cup and the bread at the Last Supper and said we were to partake of both.

Paul states that we eat the bread AND drink the cup.

There's simply no where in Scripture that says that partaking of only one element of communion is acceptable or shows the Lord's death. It's BOTH elements.

So, why have the Catholic church for all these centuries taught otherwise? And why does it still do so?

Is tradition trumping Scripture?

Again?

[Cites from 1 Cor. 11]

It is actually OR, not AND in verse 27, and eating EITHER one unworthily results in a state of being "guilty of the body AND of the blood of the Lord". No matter what species you take unworthily, the guilt is of both body and the blood.

At the same time, both the bread AND the chalice "show the death of the Lord" so the use of the prepositions is consistent with the Catholic practice.

That is a well-known Protestant forgery designed to critique communion in one species.
