Pope Francis' Apostolic Exhortation Gaudete et Exsultate focuses on instilling holiness in children from a young age. It emphasizes that children's faith formation should involve immersive learning through stories from the Bible and Catechism, taught in a child-centric way by families, schools, and communities working together. Forming children in holiness early helps develop good character and leads to harmony in families, order in communities, and ultimately peace in society.
