I went on a retreat last January sponsored by the Newark Archdiocese. I am going again this coming weekend, in a slightly larger capacity (leading a Bible study) but still primarily for growth. I'll be sure to take notes so I can provide an outline and recap. I won't be there on Sunday; I'm leaving late Saturday night because I have obligations to my own parish on Sunday.
I am looking forward very much to the evenings: overnight adoration of the Blessed Sacrament on Friday, and a Eucharistic Procession on Saturday. I'm bringing a booklet of Gregorian Chant appropriate for adoration, a Bible, and a rosary. It's been a while since I gave the Lord an hour of my time in front of the Blessed Sacrament.
