Blessing with St. Jude Oil, or if you will oil blessed with the Arm Relic of St. Jude, is a common practice among the Friends of St. Jude. Since it is NOT the Sacramental of the Anointing of The Sick, any baptized Catholic can impart this blessing. Blessings with oil touched to a relic or the tomb of one our great Saints has been a practice in the Church for over 14 centuries. The formula we recommend for use with St. Jude Oil is:
“Through the powerful intercession of St. Jude, apostle and martyr, may you be delivered for all hopelessness and despair and may God grant you every healing of body and soul, in the name of the Father+, and of the Son, and of the Holy Spirit.”
The proper gesture for making the sign of the Cross for lay people during a blessing like is to make a small Cross on the forehead of the person being blessed.
