Who We Are
Mosaic is a transformational two-year program for congregations and their leaders to embrace peacemaking as core to Christian discipleship.
What is Mosaic?
Mosaic is a program designed for church leaders and congregations looking to move beyond toxic polarization and division and form a community of peacemakers equipped to transform conflict and injustice in their neighborhood.
This two year program will fundamentally transform how participating congregations understand themselves and their communities, and they will be empowered to be countercultural places of reconciliation and healing, communities seeking to live out Jesus’ calling to be embodied peacemakers.


Our Mission
Mosaic exists to form communities of Christian leaders who pursue justice and reconciliation as central to their discipleship. We believe that when churches embrace their prophetic role in society—to speak truth, foster healing, and model love across lines of division—whole communities can flourish. Our mission is to support and equip churches to live into this calling, with courage and clarity.
Our Approach
The Mosaic Peacemaking Journey is intentionally designed to incorporate regular learning opportunities in the work of peacemaking in a variety of modes and mediums, all housed within a supportive learning cohort of peer ministry leaders.
Monthly Peacemaking Seminars
Learning from scholars-practitioners in monthly virtual seminars, we will become equipped to lead our communities through divisions into flourishing.
Immersive Learning Experiences
Cohort participants take part in our two immersive learning experiences—the US South and Ireland/Northern Ireland—offering unparalleled insights into historic and contemporary sources of conflict and what transformation requires.
Supportive Cohort Community
Alongside other clergy and congregational leaders navigating corrosive divisions, you’ll find space for honest reflection, encouragement, collaboration, and rest—united by an active, embodied hope in God’s promised Beloved Community.
Six Principles of Peacemaking
Growth
Change is always possible
Human hearts, as well as cultures and systems of power, can change. Each of us impacts our reality—for ourselves and for others. It’s not a question of whether we change our world, but how. So we practice hope: We strive for positive change, in ourselves and for others. “Hope is what you do.”—Rev. Mitri Raheb
Equity
Ownership is the Bedrock of Equality
Equality asks: Who has a seat at the table? But equity first asks: Whose table is it? We are all stakeholders in our own communities and societies. Yet many of us are treated as guests in our own homes. We build the foundations of just communities when we recognize our neighbors as shared stakeholders and protect their equal voice in shaping our communities. We can then further address ongoing inequalities by securing equally accessible opportunities for all.
Justice
Peace and Justice are Intertwined
Working for peace without justice is unserious, empty and dangerous. Working for justice without concern for healing and reconciliation can degenerate into violence and revenge. “Justice” is expansive and contested. Yet true justice enables the possibility of mutual flourishing: dignity, security, and freedom for all in equal measure. “True peace is not the absence of tension: it is the presence of justice”–Rev. Martin Luther King, Jr.
Relationship
Authentic Relationships Across Lines of Difference Fuel Transformation
Authentic relationships form the core of peacemaking. Intentionally cultivating non-transactional relationships across lines of difference provides space for individual transformation, nurtures empathy and humility, and emphasizes the humanity of those different from us. Diverse, reciprocal relationships ground our ideologies, theologies and politics in the humanity and lived experience of others. They awaken the possibility for communal, societal and systemic change.
Nonviolence
“Nonviolence Is a Way of Life for Courageous People” –Rev. Martin Luther King, Jr.
Active nonviolence promotes freedom and justice and is grounded in a spirit of love and hope. Creative and clear resistance against all forms of violence—direct, structural, and cultural—heals our world and paves the path to reconciliation. Just peacemaking is a courageous, countercultural and purpose-driven way of life.
Mutual Flourishing
The End Goal, or Telos, Is Beloved Community
Our telos is not the defeat of “enemies,” but the personal and systemic transformation that allows for mutual flourishing, reconciliation and the creation of the “Beloved Community.” We form communities that in composition and practice model the world we strive towards. Joyous, intentional, reflective, action-oriented communities replace unjust systems with just peace. “We belong to each other” – Mother Teresa
Six Practices of Peacemaking
Listen to Understand
Before we can hope to heal our world, we must first learn to see it as it actually is. We listen to understand before seeking to be understood. Deep listening cultivates curiosity while surfacing the motivations and views that underlie the issues that divide us. As we are heard and understood, opportunity opens to explore and heal. So we begin by meeting the other, and ourselves, where we are. “Love’s first act is to listen.” – Paul Tillich.
Hold competing perspectives in tension
Peacemaking recognizes that my story is not the only story. As humans, we experience our shared reality differently. Engaging the views and experiences of others, even when they do not reconcile with our own, unlocks the ability to better identify causes of and solutions to otherwise intractable conflict. “The opposite of a fact is falsehood, but the opposite of one profound truth may very well be another profound truth.” – Niels Bohr
Own our agency and responsibility
We own our duty to leave this world better than we found it. We embrace discomfort and uncertainty, which often signify and catalyze growth. We recognize that we and our communities–often unwittingly–do both good and harm. So we claim our agency and responsibility to repair harm and work for good. Yet we act with humility. We’re not here to be heroes, but servants. “To seek peace and pursue it, that is always the right thing to do. Especially when it seems impossible.” – Issa J. Khalil
Center the Leadership of the Marginalized
Being near—or proximate—to those most vulnerable is the foundation of effective, ethical movements. Those closest to a problem are best equipped to define the problem–which is the most important step in finding a just solution. And those who pay the greatest price of unjust systems often develop essential perspectives on how to transform those systems. We honor their resilience and expertise by using our platforms to amplify their voices and leadership, not imposing our own.
Self-Interrogate
Peacemaking is both an internal and an external practice. We access our power to drive change when we first allow our own hearts and minds to transform. We can then invite our families, communities, institutions and countries on similar journeys. We identify our biases, question our assumptions, and continually assess whether we unknowingly contribute to or benefit from injustice. While we never neglect to call out the unjust behaviors of our adversaries, we leverage our power within our own families and communities to urgently promote just peace. “Let there be peace and let it begin with me.” – Ainka Sanders Jackson
Advocate
We align our actions with our values. As we grow internally, we learn to lovingly challenge our families, friends, communities and institutions to address systemic injustice and work towards mutual flourishing. We amplify voices of companions, steward our limited resources, and exercise our sacred political rights in ways that transform conflict and promote just peace. Together, our actions weave the fabric of Beloved Community.
The Story Behind the Name
The mosaic art form captures the essential nature of our interconnectedness. We are interdependent. We need each other’s contributions. Others need the contributions only we can give. This is the beauty and mystery of shalom: when our relationships are in right order with God, each other, and the created order, something new emerges—something we might call flourishing and joy.
Our work in the Mosaic program is to help build the movement within the church that gives breath to this flourishing and enables shalom for all of us.
Our Staff
Mosaic is led by a team of committed peacemakers across the U.S., who oversee each facet of the program's components with expertise, care, organization, and vision. Your involvement in Mosaic will offer you and your church an immediate community of support.
