[Avodah] B'Din Heseiba L'Ikuva

[Cantor Wolberg]

I find the article very interesting. Much of it is beyond my ken of  
comprehension.
However, the one thing I'd like to submit regarding from the gemara  
Pesachim: "Matzah is a D Oraisa - a biblical commandment.
In our day Maror is only a DRabbanan - a rabbinic requirement....
By eating them together - the DRabbanan of Maror will then void the  
DOraisa of Matzah."

I was always under the impression that by violating the DRabbanan, you  
are actually committing two aveiros since
we are commanded to obey DRabbanan from DOraisa. This would be similar  
to making a brocho "...asher kidshanu b'mitzvosav
v'tzivanu..." over Shabbos or Chanukah candles (and others). You can  
argue it's DRabbanan, so how can you say "asher kidshanu"?
But that's exactly the point. DRabbanan takes on the same (or more)  
than DOraisa. Hence, how can the DRabbanan of Maror void the
DOraisa of Matzah?
