As to the breaking of the bread, it takes place right before the Communion. Usually (always?) the Agnus Dei is said or sung as the bread is broken.
If you are actually drinking blood and eating flesh, by breaking bread then you would be ripping Jesus body apart before you eat it...Is that why you guys don't take it that far???
If you really want to understand this, in light of the fact that the breaking is part of the Mass, you will do best to start here and read the next ten questions, especially Q.75, Q.76, and Q.77, and most especially Q. 77, Article 7. Whether the sacramental species are broken in this sacrament?
This is all in the public domain. Anybody who wants to know what we teach BEFORE he attacks it, can find it out with a little work.
Or, you could just tell us in a handfull of words instead of linking to page after page after page after page of human philosophers trying to convince each other that they know what they are talking about...
I couldn't say whether the answer to any questions are in there or not...I don't have enough time in this lifetime to wade thru all that...
