Equipping Leaders for Ministry


Ministry in the 21st Century

For more than half a century, Alliance Theological Seminary has been committed to preparing the next generation of servant-leaders for mission and ministry. This focus requires us to know the past and our traditions well. Future-focused education also requires many traditional disciplines to be taught within the context of ministry in the 21st century. While we have an eternal, timeless message, our methods of presenting and proclaiming that message must adjust accordingly.

To prepare leaders for ministry in today’s world, ATS is focused on three key areas of formation. Each of these formational areas are featured prominently throughout our curriculum:

  1. Spiritual Formation – ATS provides a curriculum that fosters life-changing spiritual formation. With more than 60 denominations represented, leaders are profoundly enriched in this uniquely diverse faith community.
  2. Biblical and Theological Formation –It is important now more than ever to raise up leaders with solid biblical and theological understanding who are personally transformed. Integrating this knowledge with spiritual formation will allow our students to know God deeply through the Holy Scriptures.
  3. Missional Formation – As a multicultural, evangelical seminary, ATS is committed to developing in men and women a personal knowledge of God and his work in the world in order to equip them for the ministry of the gospel of Jesus Christ and the expansion of His Church.
