You know your retreat is Catholic when it offers life-giving, empowering Catholic faith formation for a broad range of participants. In this article, I will discuss three overarching hallmarks of the Catholic ethos of faith formation, “Catholic Theological Anthropology”, “Whole-Person Engagement” and “Formation Capacities” and how faith formation retreats can be developed and evaluated accordingly by either internal or external facilitators. By the way, this article serves to inform and develop me as much as those I am hoping to encourage as I am still learning the art of faith formation facilitation.
