ACC ~ Mark 6 v13

THOSE RIGHTLY PREPARED TO ANOINT

CYPRIAN: One who is anointing should be baptized, so that having received the chrism [the anointing], he may be anointed of God, and have in him the grace of Christ. Those to be baptized and anointed with the oil of chrismation, receive the oil sanctified on the altar of the eucharist. But one who has neither an altar nor a church cannot duly consecrate the creature of oil. EPISTLE 69, TO JANUARIUS 2. [1]

[1] COG 2:201; ANF 5:376*. Not just anyone is fit to sanctify the oil, but only those duly called.
