- The Marian Medal - Mary, the First Disciple program is written for young Catholics Girl Scouts in 7th through 10th grades (ages 13-16), to grow in appreciation of Mary and in understanding themselves. They will meet Mary in Scripture as a young teenager and follow her journey, as she becomes a woman and the Mother of God. Through various projects, discussions, and liturgical celebrations over a period of months, the participants are provided with a unique opportunity to develop new insights into their personalities, friends, parents, and the world around them. The Marian Medal program book demonstrates the importance of Mary for all generations and cultures. A separate leader’s guide for adults is available.
