give in their names as Candidates for Baptism.  This invitation, described by Cyril as a call to military service (κλῆσις στρατείας)97, appears to have been often repeated on the approach of Lent.  Thus S. Ambrose, in his Commentary on S. Luke, v. 5; We have toiled all night and have taken nothing, complains, “I too, Lord, know that for me it is night, when I have not Thy command.  No one yet has given his name:  with my voice I have cast the net throughout Epiphany, and as yet I have taken nothing.” This preliminary “call to service” must be distinguished from the actual enlistment in the Christian army at Baptism, in anticipation of which Cyril prays for his hearers that God “may enlist them in His service, and put on them the armour of righteousness98.”  The same metaphorical language in reference to the Christian warfare recurs in many passages99. The next step for those who responded to the call was the registration of names (ὀνοματογραφία )100.  It appears from passages of Dionysius Pseudo-Areopagites, quoted by Bingham101, that the Bishop, after laying his hand on each Catechumen’s head, com- manded his Presbyters and Deacons to register his name, together with that of his sponsor (ἀνάδοχος) in the Diptychs of the living.  This ceremony took place at Jerusalem at the be- ginning of Lent, as we learn from Procat. § 1:  “Thou hast entered, been approved; thy name inscribed.…A long notice is allowed thee; thou hast forty days for repentance.”  Those who had been admitted as candidates for Baptism were in most Churches still reckoned among the Catechumens, being distinguished as συναιτοῦντες , “competentes.”  But from Cyril’s language in several passages it appears that in the Church of Jerusalem they ceased to be regarded as Catechumens, and were reckoned among the Faithful.  “Thou wert called a Catechumen, while the word echoed round thee from without.  Think not that thou receivest a small thing:  though a miserable man, thou receivest one of God’s titles.  Hear S. Paul saying, God is faithful.  But beware, lest thou have the title of ‘faithful,’ but the will of the faithless102.”  “Thou receivest a new name which thou hadst not before.  Heretofore thou wast a Catechumen, but now thou wilt be called a Believer (Πιστός)103.” Again, “How great a dignity the Lord bestows on you in transferring you from the order of Catechumens to that of the Faithful, the Apostle Paul shews, when he affirms, God is faithful104.” 97 Procat. § 1. 98 Ib. § 17. 99 See Cat. i. 3; iii. 3, 13; iv. 36, xvii. 36; xxi. 4. 100 Procat. § 1. 101 Antiq.
