Feast of Corpus Christi
This Sunday, the second reading will be from
Hebrews 9:11-15. I’d suggest starting at
verse 1, for context, and also reading both of the
other readings. It's lectionary #168, if you're reading from a hard copy.
Why do we believe in transubstantiation? Logistically, it seems to cause us nothing but trouble, so why is it theologically so important?
This Sunday, the readings point us to one of the reasons as laid out in the Bible. (To my mind, a case based solely on the Last Supper, when Jesus says, “this is my body”, is not a good one, because it doesn’t lay out any evidence that might actually convince a skeptic.)
In John 6, Jesus says, “Those who eat my flesh and drink my blood
have eternal life, and I will raise them up on the last day; for my
flesh is true food and my blood is true drink,” and at the last supper
he says of the bread they shared, “this is my body.”
These
(or something like them) is what most Catholics quote when challenged
on transubstantiation and think that’s the end of it, but it can’t be.
It may be enough for someone who already trusts the Church, but when
you’re challenged like this, you’re speaking to someone who doesn’t yet
have that trust. You need to show them the Church’s work, so that you can
help lay a strong foundation of reasons to trust.
