229. Why are the sacraments efficacious?
1127-1128
1131
The sacraments are efficacious ex opere operato (“by the very fact that the sacramental action is performed”) because it is Christ who acts in the sacraments and communicates the grace they signify. The efficacy of the sacraments does not depend upon the personal holiness of the minister. However, the fruits of the sacraments do depend on the dispositions of the one who receives them.
