About Saints Light
Saints Light is an independent Catholic teaching app and website made by Aquarius Mobile Studios. It teaches the Catholic faith step by step in 182 short lessons across 16 courses, with a Prayer Book of 93 prayers and a guided Rosary. Every lesson gives its Catechism paragraph numbers and Scripture references so that anyone can check it.

What it is not
Saints Light is an independent app. It is not an official publication of the Catholic Church, the Vatican or any diocese. It carries no imprimatur and makes no claim of Church endorsement. It does not replace your parish, your priest or the sacraments. If anything here differs from what the Church teaches, the Church is right and we want to know: write to Support@meetamsai.com.
Who it is for
Anyone who wants to learn the faith in order: people who are curious, adults preparing for Baptism or becoming Catholic through OCIA, Catholics coming home after years away, parents teaching their children, and parish catechists who need a lesson and a class plan.
How the lessons are written
Each lesson is written for Saints Light in plain words, in the voice of a parish catechist. A lesson has the teaching in a few short paragraphs, three or four key points, one to three Scripture quotations, the Catechism paragraphs it rests on, a one sentence summary, one thing to do that week, and three questions that explain the right answer.
Where it matters, a lesson says how firmly the Church teaches something: dogma, Church teaching, common pious belief or theological opinion. Approved apparitions are treated as private revelation, which no one is required to believe.

- Scripture in the lessons and the Rosary is quoted from the Douay-Rheims Bible, Challoner revision (1749 to 1752), which is in the public domain.
