There’s an awkward phrase inserted to make sure readers know that even when visiting the sick, the lay minister who provides this service is indeed a stopgap solution until the ordinary minister is available.
[133.] A Priest or Deacon, or an extraordinary minister who takes the Most Holy Eucharist when an ordained minister is absent or impeded in order to administer it as Communion for a sick person, should go insofar as possible directly from the place where the Sacrament is reserved to the sick person’s home, leaving aside any profane business so that any danger of profanation may be avoided and the greatest reverence for the Body of Christ may be ensured. Furthermore the Rite for the administration of Communion to the sick, as prescribed in the Roman Ritual, is always to be used. [Cf. HCWEOM 26-78]
We covered this point yesterday. But it probably bears repeating, and it’s a point I emphasize whenever I train those who are bringing the Eucharist to the sick.
