Liz Rogers, Pastoral Associate for Parish Faith Formation, Ext. 125, This email address is being protected from spambots. You need JavaScript enabled to view it.

Liz has been active in faith formation since 1993. Her first foray into religious instruction came when she volunteered to teach a fourth-grade faith formation class at St. Francis of Assisi Church. Coming from a family of teachers, she enjoyed helping others learn and the ability to pair that with her passion for faith made catechetical formation a win-win. Her first official appointment was as Adult Faith Formation Coordinator at St. Francis of Assisi where she taught Infant Baptism, RCIA and Adult Confirmation and eventually became the Director of Religious Education.

At St. Francis, Liz and her family were nurtured and supported by other families actively living their faith. It was through her daily encounters with these families that she came to see the importance of family-based faith formation and began to explore intergenerational catechesis. That led Liz to enroll in a master’s program at the Franciscan School of Theology at The Graduate Theological Union in Berkeley in 2007. Her Master’s thesis, Intergenerational Catechesis as the Primary Model of Faith Formation for the Post-Modern Catholic Church, outlined the importance of all ages sharing faith together as the most effective way to grow in faith. Much of her research came from her family’s experience of growing up around other faith-filled families.

In 2008, Liz had the opportunity to test out her theories on family-based faith formation as the Intergenerational Ministries Coordinator at The Catholic Community of Pleasanton (CCOP) where she worked until 2016. In May 2016 she returned to work in her neighborhood, taking the position of Pastoral Associate of Parish Faith Formation at St. John Vianney Church. Liz is particularly excited that this parish community has embraced family-faith formation. It is her hope that all the families of St. John Vianney will have the same loving and nurturing faith experience that were so important to her family.
