This prayer could be used for baptisms or for a blessing. It is found in a paper by Fr. Sean O'Duinn.
May the yoke of the Law of God be on this shoulder;
May the intelligence of the Holy Spirit be in this head;
May the sign of Christ be on this forehead;
May the hearing of the Holy Spirit be in these ears;
May the scenting of the Holy Spirit be in this nose;
May the vision of the People of Heaven be in these eyes;
May the conversation of the People of Heaven be in this mouth;
May the work of the Church of God be in these hands;
May the welfare of God and neighbor be in these feet;
May this heart be a dwelling place for God;
May this complete person belong to God the Father.
