Catechism of the Catholic Church
" . . . let him call for the presbyters of the Church"
1516 Only priests (bishops and presbyters) are ministers of the Anointing of the Sick. 131 It is the duty of pastors to instruct the faithful on the benefits of this sacrament. The faithful should encourage the sick to call for a priest to receive this sacrament. The sick should prepare themselves to receive it with good dispositions, assisted by their pastor and the whole ecclesial community, which is invited to surround the sick in a special way through their prayers and fraternal attention.
