A Saint John Bosco (aka St. Don Bosco) stained glass window would be a beautiful and meaningful addition to the church for several reasons: Symbolism: St. John Bosco was a Catholic priest who dedicated his life to helping young people, especially those from poor backgrounds. 
Bosco founded the Salesian order, which is still active today, and is known as the patron saint of apprentices, editors, and publishers.
A stained glass window featuring St. John Bosco would be a powerful symbol of the church's commitment to helping young people and serving the community.
Beauty: Stained glass windows are often admired for their beauty and can add a sense of the sacred to a church. The vibrant colors and intricate designs of a St. John Bosco stained glass window would be sure to capture the attention of worshippers and visitors alike.
Historical significance: St. John Bosco lived in the 19th century, and his work with young people was groundbreaking at the time. A stained glass window featuring him would be a nod to this history and a reminder of the important role that the church has played in serving the community throughout the centuries.
Fundraising: A St. John Bosco stained glass window could also be a fundraising opportunity for the church. Members of the congregation may be interested in donating money to sponsor the window or purchasing a smaller replica to take home as a memento.
Overall, a St. John Bosco stained glass window would be a meaningful and beautiful addition to any church, and could help to demonstrate the church's commitment to serving the community, while also serving as a powerful symbol of faith and inspiration for all who see it.
