Insane for the Light: A Spirituality for Our Wisdom Years is Ronald Rolheiser’s 2025 book on the spiritual work of getting old. Image published it.
It completes a trilogy, so know where to start
This is the third and final volume of a sequence Rolheiser has been writing for decades:
- The Holy Longing, on the essentials of Christian spirituality
- Sacred Fire, on the long middle stretch of adult discipleship
- Insane for the Light, on the final years
You can read this one alone. But if you are in your forties and picked it up because the title appealed, you probably want Sacred Fire instead, and if you are new to Rolheiser entirely, start with The Holy Longing.
Related fix: the search description attached to this page was actually a summary of The Holy Longing, a different book. Anyone finding this page through Google was reading about the wrong volume. Corrected.
Who it is written for
Older men and women, and specifically people in what Rolheiser calls the wisdom years. This is not a general-audience book on spiritual growth and it was misleading of this page to present it as one.
If you are in your sixties or beyond, or you are watching a parent enter that stretch, it is aimed squarely at you. If you are thirty-five, it will read as a report from a country you have not reached.
What it argues
Rolheiser’s claim is that the last phase of life has its own spiritual assignment, and that the assignment is not to keep doing what you did before, more slowly. It is to let go, and to do it well.
He is direct about what that means. Bitterness is the standing temptation of age, and forgiveness is the work that answers it. Giving up control is not defeat but the actual task. He distinguishes real hope from optimism, and argues that only the first survives a body that is failing.
The most useful thing in it is his refusal to treat later life as decline to be managed. He treats it as a stage with its own proper work, which is a genuinely different frame from most of what gets written about aging, Christian or otherwise.
A note on tradition
Rolheiser is a Roman Catholic priest, a member of the Oblates of Mary Immaculate, and served as president of the Oblate School of Theology in San Antonio. His writing draws on the Catholic contemplative tradition throughout.
Stating that plainly, and proportionately. He writes ecumenically and is widely read by Protestants, and nothing here undermines the gospel or the authority of Scripture. A Protestant reader will meet some assumptions he does not share, mostly around the sacraments and the saints, and will find the substance on aging, forgiveness, and letting go entirely usable.
What we removed
A sentence in quotation marks presented as being from the book, a customer review quote, and a paragraph describing how men “in our community” responded and felt equipped to mentor younger men. None could be verified and all are gone.
The page was also displaying a leftover template heading reading “Final CTA Block,” which was never meant to be visible, and claimed the book poses reflective questions, which we could not confirm.
Worth your time if
You are in the second half and starting to notice that the strategies which got you here are not going to carry you the rest of the way. Rolheiser is a good companion for that, unsentimental and unhurried.
It is also worth reading a decade early. Knowing what the work of that stage actually is beats arriving at it unprepared, and men in particular tend to reach it with no plan beyond continuing.
