My name is Stefen Choo. I am married to Zephyr, and we have two children, Nathanael and Nathalia.
I am a cradle Catholic, baptised as an infant and raised in a Catholic family. Growing up, I attended Mass in Mandarin and studied in Catholic schools — St. Anthony's Boys' School and St. Patrick's School.
My deeper devotion to God began during my secondary school years under the guidance of the late Brother Nicholas Seet. He helped me discover a love for Jesus in the Eucharist — something that would quietly shape my faith for many years.
Like many Catholics, my journey of faith has had its seasons.
There were periods when I stopped going to church completely. There were also years when I attended Mass mainly because I was scheduled to serve as a lector. Looking back, I now see that as a kind of grace. Even when my heart was distant, that responsibility kept me connected to God in some small way.
Eventually, I returned to regular Mass attendance, though for some time I was what many might call a “Sunday Catholic”.
At various points in my life, I encountered Protestant friends who asked questions about my Catholic faith. Their questions pushed me to start learning about Christian apologetics — how to understand and explain what the Church teaches. Through this learning, I gradually realised that the Catholic faith has deep biblical and historical foundations.
At the same time, I also noticed something else.
Many Catholics drift away from the Church not because they reject Christ, but because they were never fully taught the richness of the Catholic faith. When they encounter challenges or misunderstandings — sometimes from well-meaning but misinformed Christians — they simply do not have the tools to respond.
Recently, my own faith experienced a new period of growth.
In January 2026, I met the father of my son’s classmate. During a casual conversation, we began discussing the differences between Protestant and Catholic beliefs, as well as the history of Christianity. That conversation reignited my curiosity and my search for deeper understanding.
Around the same time, my current work as a ride-hailing driver unexpectedly became a blessing for my learning. Spending many hours on the road allowed me to listen to podcasts and talks about Scripture, Church history, and Catholic theology.
Through these teachings, many things that once seemed complicated began to make sense. The practices of the Church became clearer. The Mass became more meaningful. My prayer life became more intentional. Even the way I teach my children about the faith began to change.
After some time, I realised that I wanted to organise what I had been learning — initially just for my own reference.
But as I continued learning, another thought kept returning to me.
As a father, I realised that one day I may not always be around to answer my children's questions. Nathanael and Nathalia will continue growing, facing challenges to their faith, and searching for answers of their own. I wanted to leave behind something that could continue guiding them long after a conversation with Dad has ended.
That desire eventually became Catholic Dad SG.
Catholic Dad SG is my attempt to record what I am learning about the Catholic faith — not as a theologian or academic, but as an ordinary Catholic husband and father trying to understand God's truth more deeply and pass it on to the next generation.
What began as personal notes slowly became a library of faith: a place where I could organise what I have learned, share it with my children, and hopefully help other Catholics searching for answers as well.
So this website was born.
If you are a Catholic searching for a clearer understanding of the faith, I hope this can be one more helpful resource for you. My aim is to present the teachings of the Church in a clear, systematic and accessible way, rooted in Sacred Scripture and supported by the wisdom of the Church.
This is not a website for debates. There are already many places on the internet dedicated to arguing about religion.
Instead, imagine that we are having a relaxed conversation on my Punggol HDB balcony — enjoying a cool breeze, looking out at the trees, perhaps sharing a beer — while talking about the mysteries of the Catholic faith and the beauty of the Church.
Whether you are a lifelong Catholic, a parent trying to teach your children, someone returning to the faith, or simply a person searching for answers, you are most welcome here.
And if you have questions, feel free to reach out.
