I have never partaken of the “cup”. It always seemed redundent to me-the Host is the complete Christ, so why go to a second line to receive the exact same thing in a different form?
**Communion isn’t so utilitarian, it’s rather lavish, ie, God’s giving of Himself. Why go to the second line? It’s commended by the Church (which doesn’t order anyone to receive both) as a “fuller” sign and it was given by Christ in the Two Species. To the argument that it was only given to the Apostles that way, well, that was how they passed it on as well. While we cannot appeal to antiqurianism to counter a current practice of the Church, we can, on this and other questions, look back to Apostolic and Patristic understanding (ie., we can say it couldn’t have possibly have been that only the Apostles were to rec. in both Species, since their understanding of it and their disciples understanding of it doesn’t support that assertion). Why wouldn’t you want to receive it that way, is the question I would ask, in the absence of an allergy to alcohol (but I won’t, since the Church permits you the option)? It’s true that the Church forbade that Chalice (generally, but not a hard and fast binding without exception) around the 1200’s in answer to the heresy that One was only the Body, the Other only the Blood. She has determined (wisely, in my opinion) that it is no longer necessary to do so. Of course, you don’t have to receive from the Chalice.
