Possible Preaching Themes
Possible Scientific Resources
- Presumption, especially our own righteousness, runs the risk of blinding us to our need for God. Humbly acknowledging our need for God’s mercy opens us to growth in holiness.
- In striving for holiness, we can get caught in a spirit of individualism, reducing faith to a personal reality. Instead of “running the race” of faith alone, we must support one another on our journey into God’s reign.
- On presumptions: scientists set out to prove their presumption that light waves travel through a “luminiferous ether.” Their experiment found no evidence of ether, but they accidentally discovered that the speed of light is constant, which revolutionized physics.

- On running: The presence of other racers affects both pacing and exertion.

Homily Outline Combining Resources
Homily outline combining both resources:
About waves
- For millennia, humans have stood on the water’s edge and observed the motion of waves. But what exactly is a wave?
- Not an independent object, separate from but rather the motion of the water.
- Similarly, sound is nothing more than waves propagating through air;
- a “sound wave” is the motion of air particles pushing together and relaxing, just like ocean waves crashing on the shore.
- In the 19th century James Clarke Maxwell proved that light, too, was a wave.
- An obvious question followed: a wave of what? What is being pushed and relaxed in order to create light waves?
- It was presumed that a substance called “luminiferous ether” existed everywhere where light could travel:
- It had to exist because waves travel through substances.
- What were its properties?
- How could it be discovered, proven to exist?
- Albert A. Michelson and Edward W. Morley developed an extremely sensitive contraption, capable of proving the existence of the luminiferous ether:
- the earth travels around the sun at a very fast speed;
- a light wave traveling in the same direction as the earth should be moving much more quickly than a light wave traveling in a different direction;
- if they could show that to be true, they could prove the existence of the luminiferous ether.
- The results of the experiment were confusing:
- no change in speed was detected, regardless of the direction the light waves traveled.
- Disappointed and deflated, Michelson and Morley published their results—or lack thereof—in a paper.
- This presumed failure became one of the most significant, accidental discoveries of modern physics: light always moves at a constant speed
- a fact which revolutionized physics,
- became central to Einstein’s Theory of Special Relativity,
- now called “the most famous ‘null’ result in physics.”
- This presumed failure became one of the most significant, accidental discoveries of modern physics: light always moves at a constant speed
- Presumption of the existence of ether and the disappointment of perceived failure, inhibited Michelson and Morley from realizing the significance of their discovery!
Gospel presumptions
- Presumption in physics may delay discovery. Presumption in our faith lives is of greater concern.
- The Pharisee in today’s Gospel is certain of his own goodness, even thankful for it:
- he follows the religious law, unlike the others, even surpassing expectations
- he’s proud of who he is, clearly better than others
- he’s convinced of his own righteousness.
- The tax collector has no reason for boasting:
- he is a sinful man and knows it,
- he humbly acknowledges his sin to God,
- he recognizes his need for God’s mercy
- The tax collector goes home justified
Unexpected grace
- Our presumptions allow us to affirm that we are “good enough”:
- we make it to Mass,
- we are kind to others,
- we are charitable and give to the poor,
- we are better than a lot of people, so will surely get to heaven!
- Yet, we are all flawed and sinful, needing to grow in multiple ways.
- Recognizing that reality and our lack of progress can be disappointing—like Michelson and Morley searching for the ether.
- But what looks to us like a “null” result is often God’s undiscovered mercy and grace.
Good news:
- Jesus redeemed us from our sinfulness, revealing divine mercy and inviting us grow in holiness!
- There is no spiritual contraption to measure whether or not we have crossed that special threshold of “good enough.”
- Holiness is a lifelong relationship with the living God,
- alternately admitting our fault
- opening ourselves to new opportunities for receiving mercy
- and reentering the race with Paul toward that crown of righteousness.
- Mass can be a tax collector moment for us:
- we acknowledge our sins and weakness
- Lord, have mercy
- Forgive us our trespasses
- Lamb of God have mercy on us
- Lord I am not worthy.
- we acknowledge our sins and weakness
- The Father’s response?
- “Take and eat; receive my Son, crucified for you; become like Him: holy, filled with grace.”
- Presuming that we are good enough negatively impacts our individual and communal encounters with God’s mercy.
- We bow low, acknowledging our need for mercy.
- But we do not do this alone
- We are all in this race together
- urging each other on through word and example in this kingdom marathon.
- Just like Michelson and Morley needed the scientific community to open their eyes to their contribution
- We too need faith communities to open our eyes to new possibilities in grace.
- No matter what our effort, it is always outstripped by God’s lavish mercy and love,
- evealed in God’s abiding Spirit, who sets the pace for us to run this holy race.
