Prayers for healing are offered at SMM, usually on the first Sunday of the month after each of the masses (and at other times upon request). The healing desired might be of body, or mind, or spirit.
The priest will put his or her hands on the head of the person asking for healing and then will make the sign of the cross on their forehead using holy oil blessed by the bishop for this purpose.
Different priests will use different prayers. One used frequently at SMM is this:
Spirit of the Living God, present with us now,
Fill you in body, mind and spirit,
And heal you of all that harms you,
In Jesus's name. Amen.
