Merciful Heavens, God of Justice

October 5-7, 2018
An Ignatian, Silent Weekend Retreat for Men

Retreat Title: Merciful Heavens, God of Justice

In this retreat we will contemplate two interrelated themes. First, the glory of God’s Creation: exploring and giving thanks and praise for the beauty and majesty of God’s creation, on the earth and in the heavens.  Second, God’s justice and mercy: facing the challenge and consolation of God’s justice, in light of Pope Francis’ frequent emphasis on God’s mercy.

Groups Attending: Individuals, St. Anne (Barrington), Sacred Heart (Winnetka), Holy Family (Inverness), Joe Bussone Group, Newspaper Group

Retreat Master:


Fr. Paul Mueller, SJ

Fr. Mueller attended the Jesuits’ St. Xavier High School in Cincinnati, OH. After earning a BA in Physics at Boston University, in 1982 he entered the Society of Jesus. While preparing for ordination, he taught physics and algebra for several years at St. Ignatius College Prep in Chicago and also earned MA degrees in Philosophy, Theology, and Divinity. After being ordained a priest in 1993, he earned an MS in Physics and a PhD in History & Philosophy of Science at the University of Chicago. He served as professor of philosophy at Loyola University Chicago from 2004 to 2009, and at the same time served as Academic Dean for two programs of priestly formation at Loyola, the Jesuit First Studies Program and St. Joseph College Seminary. Since 2010 Fr. Mueller has lived and worked at the Vatican Observatory, the astronomical research institute of the Popes: initially just as religious Superior of the Observatory’s resident Jesuit community and as a member of the Observatory’s research staff, but since 2015 also as the Observatory’s Vice Director. Fr. Mueller also teaches philosophy part-time at the Pontifical Gregorian University in Rome. For most of the year he can be found at the Vatican Observatory headquarters, located in the hills southeast of Rome at Castel Gandolfo. But he spends two or three months of the year at Tucson, where the Vatican Observatory maintains its own modern telescope in affiliation with the University of Arizona.
