Book excerpt: After the excitement of the Easter Vigil, the period of mystagogy can often be overlooked by the initiation team and the neophytes. However, it is an essential part of the Christian initiation process because it helps the neophytes deepen their relationship with Christ and with the Church. Mystagogical reflection is an important part of the spiritual growth of all parishioners—from neophytes to lifelong Catholics—because it invites the faithful to reflect on their encounters with Christ in the sacraments and then consider the transformative effects those encounters have on their daily lives. A Guide to the Period of Mystagogy encourages members of the initiation team to make the most of this period and provides practical support to do so. It includes: An overview of six foundational principles of initiation ministry and how they are applied to the period of mystagogy Theological insights from the early Church’s practice of mystagogy Practical advice for implementing mystagogical reflection in your parish Nine mystagogical reflection sessions that can be used during Easter Time Fifteen mystagogical reflection sessions that can be used during the first year following initiation Encouragement to celebrate the first anniversary of baptism and to incorporate mystagogical reflection into the ongoing faith formation of the whole parish community
