We often think our children have to “grow up” before they can pursue a career, choose a vocation, or “do something” with their lives. The truth is that many great saints have done great things for God even as children. This is a list of 100 cool saints for young Catholics—girls and boys who have served God in remarkable ways before their 35th birthdays.
Some of these young people were martyrs who stood up for their faith. Others felt God’s call on their life at an early age, and responded to it. Some had visions of angels, Jesus, or His Blessed Mother. Others gave themselves to fasting, prayer or penances. These children, teens, and young adults knew God’s love in a real way and responded with their whole hearts.
