Unitas - Evangelization Model

We are living through a true epoch of change—an era in which long-recognized shifts are now fully unfolding across every dimension of life, including education. Such moments naturally bring both uncertainty and opportunity. While change can unsettle what is familiar, it also calls us forward, inviting growth, deeper reflection, and renewed commitment to mission.

In this spirit, the Unitas Evangelization Model offers a clear and faithful expression of how the Company of Mary lives and shares the Good News of Jesus today. Rooted in our charism and responsive to the needs of the present time, it guides us in forming communities of unity, purpose, and hope, where faith and learning come together in service of God’s transforming love.

We live and share the Good News of Jesus Christ through unity, purpose, and love in action

All for the Greater Glory of God

At the heart of our community is a shared call to evangelize, rooted in the charism of the Company of Mary and guided by a clear mission, a hope-filled vision, and Gospel-centered values that shape who we are and inspire all we do in service of forming hearts and transforming lives.

Evangelizing Through Education

At the heart of Unitas is the conviction that education and evangelization are inseparable. This model ensures that faith is not simply taught, but lived through every aspect of school life. Classrooms, relationships, and programs all become spaces where the Gospel is encountered. In this way, your mission is fully realized as students are formed not only intellectually, but spiritually—growing in their relationship with God while developing the knowledge and skills needed to live with purpose.

Forming Global, Faith-Filled Leaders

Unitas brings your vision to life by forming students who are prepared to respond to the needs of the world with faith, courage, and compassion. It calls young people to recognize their role in addressing real challenges—social, cultural, and environmental—through a Gospel-centered lens. This reflects the Ignatian call to form individuals who are committed to serving others, empowering students to become thoughtful leaders who act with integrity and work toward a more just and loving world.

Lived, Not Taught

The model translates your school’s core values into daily lived experiences. Through a deep personal relationship with Jesus, a commitment to finding God in all things, and a focus on care, discernment, and service, students learn to embody the values they are taught. Inspired by Mary as a model of humility and faithful response, these values move beyond words and become visible in the way students treat others, approach challenges, and grow in character.

A Culture, Not an Event

In the Unitas model, evangelization is woven into the fabric of the entire school environment. Every interaction, experience, and opportunity contributes to a culture where the presence of God is recognized and celebrated. This creates a community where students are consistently invited to discover their God-given gifts and respond to their unique calling, making evangelization an ongoing and shared mission.
