About Me

A life lived at the crossroads of law, faith, and ideas.

I came to the United States for college at Brigham Young University (BYU) in Provo, Utah in 1989 from Peru, built a career as a general practice attorney spanning three decades, raised a family, and somewhere along the way — wrote two books.

My journey of faith has been anything but straight. I served as a Mormon missionary, spent years inside the church, and eventually found my way out — not into atheism, but into something older and, to me, truer: Christian Deism. A faith closer to that of John Locke, Gotthold Lessing, or some of the Founding Fathers, like Washington, Jefferson, and also Abraham Lincoln later on. A belief in a Creator knowable through reason and nature, and in the moral and spiritual teachings of Jesus as the highest expression of what it means to be human.

DEOLOGY is the fruit of that journey — years of reading, writing, and thinking on weekends, early mornings, and stolen hours between client calls. It is a work of love.

My first book, Disyuntivas Esenciales (Essential Disjunctions), explores Latin American and US politics and culture — a subject I care deeply about as a Peruvian-American watching two worlds navigate their futures.

Outside of law and writing, I am a weekend warrior — always chasing a new project, indoors or out. I have very smart and artistic wife and children, and I love following and supporting their interests and activities.

Faith & Thought

What I believe — and why it matters

On God

I believe in a Creator who can be known through reason, nature, and the moral conscience — not only through scripture or institutional authority. This is the foundation of Christian Deism.

On Jesus

He is the supreme revelation of God on Earth and incarnated, personified divinity. The moral teachings of Jesus represent the highest expression of the Divine will accessible to humanity. The Sermon on the Mount alone is a sufficient guide for a good life, although he opened a window to the sacred and divine that we continue to explore.

On Religion

World religions are human approximations to God — born of a universal longing inherent in the human heart. Christianity, at its best, captures the truest essence of the Divine.

On Reason

Faith and reason are not enemies. "Fides quaerens intellectum" — faith seeking understanding — is not a threat to belief but its deepest expression. God intended for us to use his gift of reason as far as it can take us, and we can gradually, incrementally and progressively learn and discover more and obtain greater light on God and His nature and designs.

On America

The American founding was shaped by Christian Deist thought. Washington, Jefferson, Franklin, and Lincoln represent a spiritual tradition worth recovering and understanding. In a world that appears culturally, socially and politically rudderless, a jolt of rational Christian belief could do much to  revitalize the West and help it regain its cultural, intellectual and spiritual confidence and identity. 

On Writing

A busy lawyer and father doesn't write a 750-page theology unless he has to. DEOLOGY is a work of love — and of necessity. These ideas needed to exist in the world. I also felt that my departure from my Mormon spiritual religious roots caused a rift in my mind, heart and soul that I had to address and resolve, not just for myself but for the greater good. To contribute my "two-cents" worth to reassure others confronting a similar spiritual crisis. 

On Substack

Essays on faith, reason, and life

I write on Substack about Christian Deism, theology, law, politics, and the examined life. It's where I think out loud — between client calls and weekend projects.

If you're curious about the ideas behind DEOLOGY, Substack is where I explore them in a more conversational register.
