5.7.1 Sacramentals, Including Blessing and the Minister of Sacramentals
1. Only the rites and formulas approved by the Church are to be used in the administration of sacramentals and in the conferral of blessings, consecrations and dedications.  (They are chiefly contained in the Book of Blessings but also in the other liturgical books of the Roman Missal. The Office of Worship may be contacted regarding their proper use.)
2. No one may administer a sacramental or confer a blessing, consecration or dedication without the authorization provided according to the approved liturgical books or canon law.  The distinctions in the formularies and gestures for clergy and lay ministers are to be observed.
3. The removal of holy water from fonts during the season of Lent is not permitted, apart from its removal during the Triduum in preparation of the blessing of the water at the Easter Vigil. 
 c. 1167 §2.
 cc. 1168-1169. See the Book of Blessings, General Introduction, n. 18 for the distinctions made among those authorized to bless. Other individual liturgical texts indicate who is competent to confer particular blessings, dedications or consecrations.
