A Catholic seminarian building technology in service of preaching.
Giuseppe Njualem is a Catholic seminarian for the Diocese of St. Thomas in the US Virgin Islands. By the grace of God, and with inspiration from preacher friends and professors, he first built HomilyWriterAI for Catholic clergy. Requests from pastors in other Christian traditions then led him to build Sermon Writer AI as a denomination-aware platform without losing the human, prayerful heart of preaching.
His work sits at the meeting point of faith, pastoral care, and technology: not technology for its own sake, but technology shaped by the real demands of priestly ministry.
The Story Behind Sermon Writer AI
During his seminary studies in Canada, Giuseppe was commissioned as part of his parish practice to write Sunday homilies for his pastor, who was himself an excellent homilist. Giuseppe loved the task, but he quickly saw how demanding faithful preparation can be.
A single homily could require more than three hours of reading Scripture, biblical commentaries, magisterial documents, and the writings of the Church Fathers. That experience led to HomilyWriterAI and then to a broader question: could the same research-first approach serve preachers in other Christian traditions using the sources and convictions appropriate to each denomination?
A Providential Combination
Giuseppe had coding experience before entering seminary. As AI tools became more accessible, he used seminary vacation time to build a system that could reduce preparation time, especially research time, while keeping the preacher's own tradition, trusted sources, and pastoral judgment at the center.
The Vision: Co-Creator, Not Replacement
From the beginning, Giuseppe's primary concern was that Sermon Writer AI should never replace the preacher's insight, prayer, or personal voice. The platform is designed to make room for those things by saving time that can be given back to prayer, reflection, church life, and other essential parts of ministry.
That is why the sermon creation process is structured around what a preacher would naturally consider: Scripture, denominational tradition, theological convictions, audience, tone, occasion, and pastoral purpose. Sermon Writer AI is meant to be a faithful assistant in the work of preparation, not a substitute for the preacher.
Pope Leo XIV, AI, and the heart of preaching
Giuseppe has written a full, respectful response to Pope Leo XIV's warning about AI sermons, explaining why Sermon Writer AI is designed as a research and co-creation assistant rather than a replacement for the priest's prayer, faith, or pastoral voice.

"This project is dear to my heart because I know I will be needing a tool like this in my own future ministry, at least on those days when other aspects of priestly ministry leave no time for homily preparation. I guess we could content ourselves with saying the Spirit will guide on such occasions, but it is probably negligence on our part if a few clicks could help us be more ready and potentially even more receptive to the Spirit's promptings."
A Tool Built with Priestly Feedback
Since launching Sermon Writer AI, Giuseppe has heard from Christian preachers across traditions who use the tool in the pressure of ordinary ministry. Their feedback has helped shape improvements to the platform and has reinforced the original goal: serve preachers by making careful preparation more manageable.
Giuseppe remains committed to improving Sermon Writer AI around preachers. real needs and suggestions, so the platform can continue to support the Church's mission of preaching the Gospel clearly, faithfully, and powerfully.
