The Last Supper is the First Eucharist.  Which is why the Eucharist is such a big deal for Catholics. 

Not just because Jesus did it (after all, Jesus drove money changers out of the Temple with a whip, and we only do that once a year).  But because of what Jesus said about it.  The whole “this is my body, this is my blood” thing. 

When you hear something Jesus says at every Mass, it’s easy to miss the tone – the warmth, the wit, the edge, and even the snark.  The tone of the epistle (1 Corinthians) for Corpus Christi?  Subtle as a sledgehammer. 

No parables, no metaphors, no symbolism, no nuance.  Jesus tells us exactly what it is.  There's nothing to interpret. 

The connection?  It's exactly what happens at every Eucharist. 

More on this tomorrow.  Readings for Corpus Christi
