Christopher Ruff has authored a Discipleship Series of compact
small-group resources “for busy people with busy lives but open hearts,” which
has been used and well received in multiple US and Canadian dioceses and
parishes.
One of these is The Greatest of These is Love (2008)
which “features 6 engaging sessions, each reflecting on passages from the
writings of St. Paul on love and illustrating the themes through brief stories
of men and women touched by grace: Blessed Mother Teresa of Calcutta, St. Damien
of Molokai, St. Maria Goretti, Blessed Bartolo Longo, Irishman Matt
Talbot and Immaculee Ilibagiza. It also includes prayer and discussion
questions integral to growth as a disciple of Jesus Christ.” (This paperback has declarations of "Nihil Obstat" and "Imprimatur.")
