WCF 27.3
The grace which is exhibited in or by the sacraments, rightly used, is not conferred by any power in them; neither doth the efficacy of a sacrament depend upon the piety or intention of him that doth administer it,1 but upon the work of the Spirit,2 and the word of institution, which contains, together with a precept authorizing the use thereof, a promise of benefit to worthy receivers.3
