Senior Leadership

91ºÚÁÏÍø / ACSI / About ACSI / Senior Leadership

Larry TaylorI am inspired by the faith, courage, and reverence for God by Christian educators around the world! It reminds me of the story recounted in I Samuel 17 about David defeating Goliath. In verse 29, David’s response to the inaction of his elder brothers and the Israelites especially encourages me. He boldly and nobly answers the call to action by asking, "Is there not a cause?”

I can think of no greater cause than to partner with you as you advance Kingdom education. We fully believe that authentic devotion to the Christian faith and academic excellence are mutually reinforcing. There are not two or three forms of excellence, but rather an ethos that is cultivated throughout every facet of our schools. Faith is not separated from learning but rather integrated intentionally, resulting in a distinctive Christian worldview.

Scholarship and learning become an integral component to the maturation process known as discipleship. Thus, becoming a disciple of Jesus Christ, the ultimate objective of the Great Commission (Matt. 28:16-20), is the prize for which we strive; it is the highest form of excellence! It is certainly conceivable that we could produce students with the spiritual depth needed to enter our pluralistic society and not fall prey to empty philosophies. Rather, they would be equipped to saturate the marketplace to which God has called them with confidence, purpose, and an eternal perspective.

ACSI’s ongoing mission is to strengthen Christian schools and equip Christian educators worldwide as they prepare students academically and inspire them to become devoted followers of Jesus Christ. We want to serve you as you continue to cultivate and sustain a flourishing school. Please let us know if there is anything we can do for you—thank you for your obedience to God’s call on your life—you are indeed making a difference.

In the Era of School Choice, ACSI Releases ‘Teaching Christianly’ to Equip Faith-Based Educators

Mar 17, 2026, 10:29 by Brittany Steward

 

 

The 91ºÚÁÏÍø (ACSI) is pleased to announce the release of “Teaching Christianly” by Dr. Mark T. Witwer, a concise and practical guide designed to help educators thoughtfully integrate faith into both what they teach and how they teach it.

In a time when school choice is growing nation-wide, more students are attending Christian schools. Witwer’s book helps to equip teachers to integrate faith in the classroom, ultimately advancing the mission of Christ-centered education.

Witwer has more than four decades of experience in Christian education, primarily as a middle and high school math teacher. He is currently the adjunct professor of Christian education at Knox Theological Seminary in Fort Lauderdale, Florida.

“I had to bring my faith into conversation with both what and how I taught,” Witwer shared.

Written as a foundational resource for Christian educators, “Teaching Christianly” offers a clear framework for both new and veteran teachers. New educators gain a clear framework for faith-informed instruction, while experienced teachers are invited to reflect on and refine their practice.

ACSI has also developed an accompanying online course in partnership with Witwer and Dr. Kerri Miner, Head of School at Christ Classical Academy of Charlotte. The course features short videos from Witwer, classroom demonstrations from master teachers, interviews, reflection prompts, and interactive activities. Available in both group and individual formats, the book-and-course bundle is designed to renew educators in their calling and equip them to teach Christianly at every grade level and subject area.
