cf. note on p. 42. St. Cyprian (Ep. lxx.) says that heretics who have no true altar cannot have oil sanctified by the altar. “Gregory of Nazianzus, Orat. (xlviii in Jul.) speaks of oil sanctified or consecrated on the spiritual or divine table; Optatus of Milevis (c. Don. vii. 102) says that this ointment is compounded (conditur) in the name of Christ; and the Pseudo-Dionysius (De Hierarch. Eccles. c. 4) mentions the use of the sign of the cross in the consecration of it.” D.C.A. i. 355.
