The Grammar of the Heart - Introduction

How Prayer, Repentance, and Grace Teach Us to See

“Blessed are the pure in heart, for they shall see God.”

— Matthew 5:8

The Grammar of the Heart is a nine-part series exploring how prayer, repentance, suffering, and the ascetical tradition gradually form not only what we believe about God, but the way the heart learns to see Him. This is the Introduction.

_______

There comes a point in the spiritual life when the question is no longer simply what we believe.

The question becomes what our believing has made of us.

We may spend years learning the language of faith. We read Scripture. We study theology. We learn the teachings of the Church. We acquire words for grace, repentance, mercy, prayer, communion, judgment, salvation. We learn what Christians are supposed to believe about God and about the human person.

All of this matters. Truth matters.

But there is another knowledge that comes only slowly.

It is the knowledge that forms within us through years of standing before God.

Prayer teaches it. Repentance teaches it. Suffering teaches it. Failure teaches it. Forgiveness teaches it. Silence teaches it. The liturgy teaches it. The repeated invocation of the Holy Name teaches it. And sometimes the things we would never have chosen become its most severe and faithful teachers.

Eventually something begins to happen that is difficult to describe.

The truths we have confessed begin to descend into the heart.

And when they reach the heart, they do not remain unchanged.

Neither do we.

The Heart Learns a Language

For many years I thought of spiritual formation primarily in terms of learning: reading the Fathers, acquiring theological understanding, developing a rule of prayer, struggling against the passions, learning watchfulness, returning again and again to repentance.

I still believe all of these things are necessary.

But looking back over the years, I have begun to see that something quieter was taking place beneath them.

The heart was learning a language.

Not a vocabulary.

A grammar.

There is a difference.

A vocabulary gives us words. A grammar determines how those words relate to one another and, eventually, how we understand what is being said.

The spiritual life possesses such a grammar.

Mercy means something different after we have needed mercy.

Providence means something different when the future we carefully constructed disappears.

Repentance means something different when we discover that it is not primarily punishment but return.

Silence means something different when every explanation has failed us.

Obedience means something different when there is nothing left to accomplish and someone simply needs us to remain beside them.

The Cross means something different when it ceases to be an idea and becomes the shape of the life we have actually been given.

And God Himself is known differently when we have exhausted our attempts to manage Him.

The words may remain the same.

The heart hearing them has changed.

Newman at the Threshold

There is a Western voice who helps illuminate the beginning of this movement.

St. John Henry Newman, in An Essay in Aid of a Grammar of Assent, distinguished between notional and real assent. We can apprehend a truth notionally - we can understand a proposition and affirm that it is true - without that truth yet possessing the immediacy and concreteness of something personally known.

Real assent is different. Reality has drawn near. What was once held principally as an idea takes hold of the concrete person.

Newman’s concern was profound: How does a human being actually come to certitude? How do the accumulated experiences, probabilities, judgments, movements of conscience, and perceptions of a lifetime converge in the living act of assent?

His question has accompanied me for many years.

But the desert seems to ask another question beyond it.

What happens after assent?

What happens when a truth that has become real to us passes through decades of prayer, repentance, ascetic struggle, worship, suffering, failure, forgiveness, and grace?

What happens when truth does not simply convince the person but begins to transform the person who knows it?

Here, I think, we approach what I mean by the grammar of the heart.

God Is Merciful

Take perhaps the simplest example.

God is merciful.

At one level, this is a proposition.

I believe that God is merciful.

The words may be completely sincere. I may defend them theologically. I may find them throughout Scripture. I may preach them to others.

Yet another movement is possible.

I entrust myself to the mercy of God.

The proposition has become personal. I no longer merely affirm mercy; I stake my life upon it.

But the ascetical tradition carries us further.

I repent before the God whose mercy I have come to know.

Repentance itself begins to change. It is no longer principally the frightened movement of a servant attempting to escape punishment. It becomes the movement of the prodigal who remembers the Father’s house. Mercy makes repentance possible.

And perhaps, after many years, something deeper happens still.

I begin to see everything through mercy.

I see my sins through mercy.

I see my weakness through mercy.

I see another person’s failure through mercy.

I see suffering through mercy.

I see judgment through mercy.

I even begin, however imperfectly, to see those who have wounded me through mercy.

Mercy has ceased to be merely something I believe about God.

It has become part of the grammar by which my heart perceives reality.

From Assent to Transformation

We might describe this movement in a simple way:

notional assent → real assent → ascetical embodiment → phronema

It is not a ladder. It is certainly not a technique. Human beings do not progress neatly through spiritual stages.

Grace refuses our diagrams.

But the movement tells us something important.

Newman helps us understand how truth moves from proposition toward personal assent.

The desert asks what happens when assent itself enters the furnace.

The Fathers are interested not merely in whether we believe the truth but whether the truth has purified the nous, softened the heart, reordered the passions, and changed the way we behold God and our neighbor.

They are concerned with phronema.

This word is difficult to translate adequately. It means more than mentality and more than worldview. It suggests a disposition of mind and heart, an orientation of the whole person—a way of perceiving reality formed by participation in a particular life.

This is why the Fathers cannot finally be understood simply by reading them.

They must be inhabited.

The Philokalia is not merely a collection of texts. The sayings of the Desert Fathers are not spiritual aphorisms. St. Isaac the Syrian is not presenting an interesting theory about divine mercy. St. Silouan is not offering a psychological technique when he tells us to keep our mind in hell and despair not. St. Sophrony is not constructing an intellectual system when he speaks of standing before God with the whole Adam in one’s heart.

They are describing a world perceived by hearts that have been purified through repentance.

To understand them fully, one must begin to breathe the same air.

When the Heart Begins to See

This helps explain something I have increasingly recognized in my own life.

For nearly forty years I have read the ascetical Fathers of the Christian East. At first I read them with fascination. Then I began to teach them. Later I wrote about them. I tried, however imperfectly, to order my prayer according to what they taught.

But only gradually did I recognize what all that reading and praying was doing.

The Fathers were not merely giving me ideas.

They were teaching my heart how to see.

St. Isaac taught me to look for mercy beneath judgment.

The desert taught me that repentance is not self-hatred but the return of the whole person to God.

The Jesus Prayer taught me that prayer can become simpler and simpler until almost everything disappears except the Name.

Silence taught me that not every question requires an answer.

Suffering taught me that Providence often looks nothing like the future we imagined.

Caregiving taught me that the one thing needful may sometimes be the person sitting immediately before us.

Loss taught me that God remains when the structures through which we once knew Him begin to fall away.

And the modern elders taught me that the Christian life ultimately concerns the enlargement of the heart until there is room within it for the suffering of another.

None of these things came quickly.

Some of them are still being learned.

Perhaps all of them are.

The Danger of Borrowed Language

There is also a danger here.

We can learn the vocabulary of the spiritual life without acquiring its grammar.

We can speak fluently about hesychia while remaining incapable of silence.

We can quote the Fathers on humility while defending ourselves at every wound.

We can speak about Providence while secretly demanding that God explain Himself.

We can praise obedience while obeying only when obedience confirms what we already desire.

We can speak about the Jesus Prayer while remaining almost entirely absent from the Jesus whose Name we invoke.

We can even acquire the language of the desert as another form of identity.

The Fathers are merciless toward this illusion.

They continually return us to fruits.

Does prayer make us gentler?

Does repentance make us less interested in the sins of others?

Does silence free us from the need to justify ourselves?

Does suffering enlarge the heart?

Does theology lead us to worship?

Does our knowledge of God’s mercy make us merciful?

If not, something has remained at the level of words.

The grammar has not yet become our own.

The School of Reality

This is why life itself becomes part of our spiritual formation.

We often imagine that the spiritual life occurs during the explicitly religious portions of the day: the Psalter, the Jesus Prayer, the Divine Liturgy, spiritual reading, fasting.

But these things prepare the heart to encounter reality.

And reality reveals whether the heart has learned what prayer was trying to teach it.

The interruption.

The person who needs us when we are tired.

The prayer that feels empty.

The body that begins to weaken.

The vocation that changes shape.

The community that disappoints us.

The future that refuses to arrive.

The unanswered letter.

The door that closes.

The long season in which God gives no explanation.

These are not interruptions of the spiritual life.

They are often where its grammar is learned.

The cell of the monk was never simply a room.

The cell is the place where escape becomes impossible and the heart is forced to become truthful.

Sometimes life itself becomes that cell.

Another Language

There are moments when we discover that this long formation has changed us more deeply than we realized.

We hear words that once satisfied us and discover that they no longer reach the deepest place.

We encounter another way of speaking about God and recognize something strangely familiar.

Not because it is novel.

Because the heart already knows its cadence.

This recognition can be unsettling.

We may discover that years of prayer have carried us somewhere our conscious plans never intended to go.

The mind may still be trying to understand what the heart has slowly learned through prayer.

This does not mean that every interior attraction is revelation. The heart can deceive itself. Desire requires discernment. Experience must be tested. No one becomes his own spiritual authority merely because something feels profound.

Indeed, the deeper the movement, the greater the need for humility.

But neither should we pretend that formation leaves us unchanged.

There comes a time when we must ask what kind of person our prayer has actually formed.

What do we instinctively believe about God when suffering comes?

Where does the heart turn when explanations fail?

What understanding of repentance has become natural to us?

What kind of holiness do we recognize when we encounter it?

What spiritual air allows us to breathe?

These questions may tell us more than we expect.

The Reflections That Follow

The reflections in this series will explore something of this interior grammar.

Mercy.

Repentance.

Providence.

Silence.

Suffering.

Obedience.

Prayer.

Conscience.

Freedom.

The passions.

The Jesus Prayer.

The remembrance of death.

The purification of the heart.

The enlargement of the heart.

And eventually phronema itself—the transformation by which Christianity becomes not merely what we believe but the reality from within which we see.

I do not approach these things as one who has mastered them.

Quite the opposite.

Increasingly, I find myself standing before mysteries that have become larger rather than smaller with time.

But perhaps that too belongs to the grammar of the heart.

In youth we imagine that knowledge will eventually allow us to possess the truth.

Later we discover that truth has been patiently dispossessing us.

Prayer strips away words.

Repentance strips away illusion.

Suffering strips away control.

Love strips away self-protection.

Silence strips away the need to be understood.

And somewhere beneath all that remains the simplest reality:

God is.

I am before Him.

And this is enough.

Perhaps the deepest transformation occurs when the heart no longer needs to possess God, explain God, defend God, or arrange the future in His name.

It simply turns toward Him.

Again.

And again.

And again.

Until turning toward God becomes something like breathing.

Until mercy becomes the way we see.

Until repentance becomes homecoming.

Until prayer becomes the Name.

Until the stranger becomes our brother.

Until suffering no longer proves that God has abandoned us.

Until silence is no longer empty.

Until the heart begins to recognize everywhere the One whom it has been seeking all along.

The doctrine has not changed.

God has not changed.

The heart has been changed enough to perceive what was always there.

We have not merely learned another vocabulary.

The heart has learned another language.

And perhaps the Christian life is, in the end, the long surrender by which that language becomes our own.
