Fides
Deposit of Faith · Apologetics · Support
Hard questions. Real comfort.
Grounded in the Deposit of Faith.
Whether you are defending the Catholic faith in a live conversation, preparing for Confession after years away, or carrying grief and anxiety at 2 AM — Fides answers from Sacred Scripture, the Catechism, the Church Fathers, and St. Thomas Aquinas.
Built for 1 Billion Catholics — $1 / Month
Other Catholic apps charge $70/year, locking out 95% of the global Church. Fides is $1/month — and every Evangelist Pass sponsors 10 seekers, students, or Catholics in developing nations.
