The seven sacraments are the main expressions of the Church's life, and in the lives of the saints, we see the concrete effects of their power. This brief booklet accompanying Bishop Barron's Sacraments study program was created to help you to come to a deeper understanding of these channels of grace through some of the great holy men and women of the Church, including Pope St. John Paul II and Sts. Louis and Zélie Martin, and to seek out the sacraments--and the holiness of life they produce--with renewed clarity and energy.
