13 We have declared, then, why it was at the tenth hour. Let us see what follows: “One of the two which heard John speak, and followed Him, was Andrew, Simon Peter's brother. He finds his own brother Simon, and says unto him, We have found the Messias, which is, being interpreted, the Christ.” Messias, in Hebrew; Christ, in Greek; in Latin, Anointed. Χρῖσμα is anointing in Greek; Christ, therefore, is the Anointed. He is peculiarly anointed, pre-eminently anointed; wherewith all Christians are anointed, He is pre-eminently anointed. Hear how He speaks in the psalm: “Wherefore God, Your God, has anointed You with the oil of gladness above Your fellows.” For all the holy ones are His fellows, but He in a peculiar sense is the Holy of Holies, peculiarly anointed, peculiarly Christ.
