As a transitional deacon I collaborated with Christina at MIT’s Catholic chaplaincy. One of the year’s highlights was an extended catechesis we offered on the structure and meaning of the Mass. Despite years of studying the Mass in preparation for the priesthood, I learned so much from Christina’s portion of our presentation! For example, she unpacked the Jewish roots of Penitential Act of the Mass in a way I still remember when I celebrate the Liturgy in my parish. Christina approaches topics with extensive knowledge of the Church’s Tradition and deep faith.— Fr. John Peck, SJ
