The retreats are held at Featherock Conference Center in Schulenberg, Texas.
The retreats are run by a lay director and a priest of Opus Dei
Yes, the retreats are silent retreats aimed primarily at fostering an intimate dialogue between the participant and God.
There are a number of events every day including guided times of prayer by the priest, a talk, stations of the cross, and a chance for spiritual guidence though talking one on one with the priest which facilitate this dialogue with our Lord.
