What makes Spirit of Truth unique?

Spirit of Truth is a refreshing resource that lightens your burdens while helping you lead your students to a profound encounter with Christ. Here is what makes Spirit of Truth unique:

You’re in Control

Our teacher’s guides are designed to give you complete control over how you teach. You can use the modular lessons and activities our team of high school teachers have developed, or you can substitute your own lessons whenever and however you want.

Student Texts are Challenging Yet Accessible

We carefully crafted our student textbooks to be both readable and academically-challenging. Our textbooks help students see that the Catholic Faith not only makes sense but leads them to live a virtuous life in service to God and one another.

You’ll Save Time

We provide a fully-developed, interactive lesson for each day of the school year, which includes readings, critical thinking questions, discussion points, sacred art reflections, saint stories, primary source excerpts, answer keys, and much more.

You’ll Lead Your Students on a Spiritual Journey

While it’s important for your students to understand the principles of the Faith, Spirit of Truth is designed to help them internalize the Faith and apply it to their own lives. The results are students with strong foundations and tools for their current and future spiritual growth.
