After a Theology Congress organized in 2015 by the Theology Faculty of the Regina Apostolorum Pontifical Athenaeum in Rome, a group of Regnum Christi Members including Fr. Pedro Barrajón, LC; Fr. Nicolas Bossu, LC; Fr. Andrew Dalton, LC; Fr. Nikola Derpich, LC; Mauro Gagliardi; Fr. David Koonce, LC; Emilio Martínez Albesa; Matteo Monfrinotti; Fr. José Enrique Oyarzún, LC; Fr. Devin Roza, LC; Angela Tagliafico; Laurent Touze; Fr. Cristobal Vilarroig, LC; and George Woodall came together to contribute to this work which explores the Kingdom of Christ in a deep and well-rounded way. The goal of the congress was a more profound understanding, biblically, theologically, and historically, of the Kingdom of Christ, to prepare for the Jubilee year of the 75th anniversary of the Legionaries of Christ in 2016, a religious congregation that forms part of the Regnum Christi Federation.
