Over years of living, working and travelling in many countries, I have sometimes encountered the sacred in forms very different from my own Christian tradition. A few experiences remain especially vivid: staying on the White Earth Reservation in Minnesota, where I attended Chippewa powwows; staying with Indigenous communities in northwestern Washington State, where I attended a Makah potlatch; visiting Shinto shrines in Japan; and, later, while living and working in Pakistan, spending time at Sufi sites and attending many gatherings of Sufi devotional music. These are simply a few of the encounters that come most readily to mind, and each belongs to a distinct tradition that I would not pretend to understand fully from within. Yet for all their differences, I saw, heard and felt something deeply resonant in the ways that place, rhythm, repetition, music, silence and shared ritual can carry meaning beyond ordinary speech and make the sacred feel close. Those experiences have stayed with me, shaping how I approach the Christian mystics—not as remote historical figures, but as people who found, within their own tradition, ways of becoming more attentive to God.
The word mystic can sound mysterious. It may bring to mind extraordinary visions, voices from heaven or spiritual experiences far removed from ordinary life. Yet many of the great Christian mystics wrote about questions that remain deeply familiar: How do we begin to pray? What do we do when God feels distant? Can prayer continue when we are distracted, tired or uncertain? How do we trust in mercy? And how might prayer change the way we live?
Christian mysticism is not primarily about seeking unusual experiences. At its heart is a longing for a deeper relationship with God—a relationship shaped by prayer, love, trust and a growing awareness of God’s presence. The mystic saints did not all pray in the same way. Their personalities, circumstances and spiritual journeys were remarkably different. Some experienced vivid visions. Some found God in silence. Some wrote poetry. Some served the poor, advised rulers or founded religious communities. Their lives remind us that there is no single personality suited to prayer. Here are five mystic saints and five gentle lessons they offer to anyone seeking a deeper life of faith.
Saint Teresa of Ávila: Prayer Is Friendship with God
Saint Teresa of Ávila was born in Spain in 1515. A Carmelite nun, reformer and writer, she became one of the great teachers of Christian prayer. Teresa was intelligent, warm, practical and often humorous. Although her writings describe profound mystical experiences, she also wrote openly about distraction, tiredness and the difficulty of remaining attentive during prayer.
She did not pretend that prayer was always easy. For Teresa, prayer was fundamentally a relationship. She described it as spending time with a friend—being alone with the One whom we know loves us. This makes prayer feel less like a performance. We do not need perfect words. We do not need to arrive in the right mood. We do not need to hide our worries, frustrations or uncertainty. Friendship grows through presence. Sometimes conversation flows. Sometimes there is silence. Sometimes we arrive distracted and need time to settle. What matters is the willingness to return.
The Interior Castle
Teresa imagined the soul as a beautiful crystal castle containing many rooms. At the centre of this castle is the presence of God. Her spiritual classic, The Interior Castle, describes prayer as a gradual journey inward. We move through the rooms not by escaping ordinary life, but by growing in humility, self-knowledge, trust and love. Many people remain near the outer walls, surrounded by noise and distraction. Yet the door remains open. Prayer is the way in. Teresa’s image reminds us that God may be closer than we imagine. The spiritual journey is not always a search for something distant. It may also be a journey towards the sacred centre already waiting within us.
What Saint Teresa teaches us
Prayer does not have to be impressive. Begin by being present. Speak honestly. Sit quietly. Return when distracted. Trust that time spent with God is never wasted.
Saint John of the Cross: Prayer Can Continue in Darkness
Saint John of the Cross was born in Spain in 1542 and became a Carmelite friar, priest, poet and spiritual teacher. He worked closely with Teresa of Ávila in reforming the Carmelite order. His path was not easy. He experienced opposition, imprisonment, loneliness and suffering. During one of the darkest periods of his life, he wrote poetry of extraordinary beauty. John is most closely associated with the phrase the dark night of the soul.
Today, those words are often used to describe sadness, depression or a difficult period in life. In John’s writings, however, the dark night has a more particular spiritual meaning.
It describes a time when familiar feelings of comfort or certainty fall away. Prayer may feel empty. God may seem distant. Practices that once brought peace may no longer feel helpful. Yet John did not believe that this silence necessarily meant God had disappeared. Sometimes faith is being deepened beyond feelings.
When prayer feels empty
Many people quietly assume that they are failing when prayer becomes dry. They may wonder whether they have lost faith or done something wrong. John offers another possibility. A person may be learning to love God without depending entirely upon consolation, emotion or certainty. Beneath the silence, something may still be changing. This does not mean that every experience of suffering has a hidden spiritual explanation. Nor does it mean that pain should simply be endured without seeking help. John’s lesson is gentler: The absence of a feeling is not always the absence of God.
What Saint John teaches us
Prayer does not become meaningless simply because it feels quiet. During difficult seasons, prayer may be as small as remaining open:
“I am here.”
“Stay with me.”
“Help me through today.”
Faith can continue even when we cannot see the road ahead.
Saint Hildegard of Bingen: Prayer Helps Us See Creation Differently
Saint Hildegard of Bingen was born in Germany in 1098. She became a Benedictine abbess, visionary, writer, composer and student of the natural world. She wrote about theology, music, plants, healing and the relationship between humanity and creation. Hildegard experienced visions from childhood. She described perceiving them while awake, within what she called the reflection of the living Light. Her spirituality was filled with colour and movement. Stars, flames, flowing water, music, trees and living creatures appear throughout her writings. For Hildegard, creation was not separate from the life of faith. The natural world revealed something of the beauty, generosity and creative power of God. One of the ideas most closely associated with her is the Latin word viriditas. It is often translated as “greenness,” “green vitality” or “the greening power of God.” Hildegard saw the energy that causes seeds to grow, leaves to unfold and the earth to renew itself as a sign of divine life. She also applied this image to the human soul. We can experience seasons of spiritual dryness, but new growth remains possible.
Prayer as attention
Hildegard invites us to notice. A bee moving among flowers. Rain darkening dry soil. The first green shoot after winter. Birdsong returning in spring. Prayer does not always require withdrawing from the world. Sometimes it begins by looking more closely at what is already around us. Creation can teach gratitude, patience and wonder.
What Saint Hildegard teaches us
Make room for attentiveness. Walk slowly. Notice what is growing. Allow beauty to become gratitude. Prayer may begin in a church or beside a candle—but it may also begin in a garden.
Saint Faustina Kowalska: Prayer Begins with Trust in Mercy
Saint Faustina Kowalska was born in Poland in 1905. She entered the Congregation of the Sisters of Our Lady of Mercy and lived a relatively hidden life, working as a cook, gardener and porter. Yet within that ordinary life, Faustina experienced a profound spirituality centred upon the mercy of Jesus. Her diary records visions, prayers, struggles and reflections that helped inspire the Divine Mercy devotion. The words most closely associated with her are simple:
Jesus, I trust in You.
Trust can sound easy when written in a short sentence. Living it is often more difficult. Many people carry regret, shame or a fear that they are somehow beyond forgiveness. Others believe that they must first become better before approaching God. Faustina’s message moves in the opposite direction. Mercy is not a reward for people who have already made themselves perfect. It is a gift.
Prayer when we feel unworthy
Faustina’s spirituality encourages honesty. We do not need to disguise our mistakes or pretend that we have everything together. Prayer can begin with the truth:
“I need mercy.”
“I am struggling to trust.”
“Help me begin again.”
Her message is not that our choices do not matter. Mercy invites change, reconciliation and a more compassionate way of living. But transformation begins with being loved—not with earning the right to be loved.
What Saint Faustina teaches us
Bring your whole life to prayer, including the parts you would rather hide. Trust does not always mean feeling certain. Sometimes trust is simply choosing to return.
Saint Catherine of Siena: Prayer Should Lead Us Towards Love in Action
Saint Catherine of Siena was born in Italy in 1347. From an early age, she felt drawn towards a life of prayer. She later became a Dominican tertiary, serving people who were poor and sick while remaining deeply involved in the religious and political struggles of her time. Catherine was not a quiet figure standing at the edge of history. She wrote letters to rulers, church leaders and ordinary people. She urged peace, challenged corruption and called for reform. Her mystical life did not remove her from the world. It sent her more deeply into it. Catherine experienced prayer as an encounter with the immense love of God. Yet that love demanded a response. If prayer makes us more aware of God but less compassionate towards other people, something has gone wrong.
The cell within
Catherine spent long periods in solitude during the early part of her spiritual life. Later, as her responsibilities grew, physical solitude became less possible. She wrote about carrying an inner place of prayer with her—a quiet interior space to which she could return even while active in the world. This is a helpful image for busy lives. Many people cannot spend hours in silence. Work, family, caring responsibilities and daily demands fill the day. Yet brief moments of recollection remain possible. A prayer while washing dishes. A pause before answering a difficult message. A moment of gratitude while travelling. A silent request for patience. The inner room of prayer can travel with us.
What Saint Catherine teaches us
Prayer and action belong together. Let prayer make you more attentive to the needs of others. Carry a small place of stillness within you—and allow the love found there to shape what you do next.
Five Different Doorways into Prayer
These five saints offer very different images of the spiritual life.
Saint Teresa invites us into friendship.
Saint John remains faithful through darkness.
Saint Hildegard notices divine life within creation.
Saint Faustina trusts in mercy.
Saint Catherine carries prayer into compassionate action.
We may feel naturally drawn towards one of these approaches. Perhaps prayer feels most real during a quiet conversation with God. Perhaps we are passing through a season in which prayer feels dry. Perhaps the garden, hills or changing seasons awaken gratitude. Perhaps we need to hear that mercy is still available. Perhaps our prayer needs to become practical love. There is room for all of these paths. The mystic saints do not ask us to imitate every extraordinary experience recorded in their lives. They invite us to become more attentive to God. To return. To trust. To remain open. And to allow prayer, slowly and quietly, to change the way we see ourselves, one another and the world around us.
A Prayer Inspired by the Mystic Saints
God of friendship, light and mercy,
teach us to pray.
When we are distracted,
help us return.
When the way feels dark,
remain close to us.
When the world becomes hurried,
teach us to notice beauty,
growth and the quiet signs of your presence.
When we carry regret,
help us trust in mercy.
When we encounter suffering,
let our prayers become compassion and our compassion become action.
Through the example of Teresa, John, Hildegard, Faustina and Catherine,
draw us towards a deeper life of faith,
not through extraordinary experiences,
but through ordinary acts of trust,
attention,
courage and love.
Amen.
Frequently Asked Questions
What is a Christian mystic?
A Christian mystic is someone whose spiritual life is marked by a deep awareness of, and longing for, union with God. Some mystics experienced visions or other extraordinary events, but Christian mysticism is fundamentally centred upon prayer, love of God and spiritual transformation.
Do you need to have visions to practise contemplative prayer?
No. Visions are not the purpose of prayer and are not necessary for a deep spiritual life. Silence, Scripture, honest conversation with God, gratitude and simple attention can all become forms of prayer.
Which mystic saint is associated with the Interior Castle?
Saint Teresa of Ávila used the image of the soul as an interior castle containing many rooms. At its centre is the presence of God. Her book The Interior Castle describes the gradual journey towards deeper prayer and relationship with God.
What is the dark night of the soul?
The phrase comes from the writings of Saint John of the Cross. It describes a period of spiritual purification in which familiar feelings of comfort or closeness to God may disappear. It is not simply another name for sadness or depression, although difficult emotional experiences may sometimes accompany spiritual struggle.
What does Saint Hildegard’s word viriditas mean?
Viriditas is often translated as “greenness,” “green vitality” or “the greening power of God.” It expresses the life-giving energy visible in creation and the possibility of renewal within the human soul.
What is the central message of Saint Faustina?
Saint Faustina’s spirituality centres upon the mercy of God and an invitation to trust in Jesus. The words “Jesus, I trust in You” are closely associated with the Divine Mercy devotion inspired by her writings.
How can I begin a simple daily prayer practice?
Begin with a small amount of time that feels sustainable. Sit quietly, speak honestly to God, read a short passage from Scripture or simply give thanks for something you have noticed. Prayer does not need to be long or eloquent. The important thing is to begin—and to return.
