“Why, therefore, is the Head itself, whence that ointment of unity descended, that is, the spiritual fragrance of brotherly love,—why, I say, is the Head itself exposed to your resistance, while it testifies and declares that ‘repentance and remission of sins should be preached in His name among all nations, beginning at Jerusalem’? And by this ointment you wish the sacrament of chrism [confirmation] to be understood, which is indeed holy as among the class of visible signs, like baptism itself.” St. Augustine  (Letters of Petilian the Donatist, 2,104:239 [A.D. 403], in NPNF 1, IV:592)
