From a reader…
Can a Bishop give a permanent Deacon (Military Ordinariate) the authority to administer the Sacrament of the Sick?
NO! One hundred times… NO!
Deacons are not able to administer Anointing of the Sick.
Only the sacerdos (which term includes both priest and bishop) can anoint. Deacons cannot anoint. Period.
If a deacon attempts to anoint he simulates a sacrament, which is a grave abuse and, if he knows this, a grave sin. However, he should know this, since it pertains to what he must know for his ministry in the Church. Furthermore, every bishop should know this too.
If this is going on, the bishop, the local diocesan bishop or the Congregation for the Doctrine of the Faith must be informed.
For questions about how the rite is to be conducted, one can have recourse always to the Congregation for Divine Worship and Discipline of the Sacraments. In the case of the question about validity of a sacrament in a concrete case you must have recourse to the Congregation for the Doctrine of the Faith.
