§ 4.  Candidates for Baptism.  Bingham, who himself makes four classes or degrees of Catechumens, acknowledges that “the Greek expositors of the ancient Canons,” and other writers, “usually make but two sorts Ant. X. ii. 1–5.  The Council of Nicæa, Canon xiv., seems to speak only of two classes..”  These were (1) the imperfect (ἀτελέστεροι), called also hearers (ἀκροώμενοι , audientes), because in Church they were only allowed to remain till the Holy Scriptures had been read, the Sermon preached, the special prayers of the Catechumens said, and the blessing given to each by the Bishop in the words of the “prayer of the imposition of hands Const. Apost. viii. § 6..”  After this the Deacon says, “Go out, ye catechumens, in peace.”  (2)  After the Energumens also have been dismissed, the more perfect (τελειότεροι, φωτιζόμενοι) remain on their knees in prayer (γονυκλίνοντες, εὐχόμενοι).  Then the Deacon is to cry aloud, “Ye that are to be illuminated, pray.  Let us the faithful all pray for them.  And being sealed to God through His Christ, let them bow down their heads, and receive the blessing from the Bishop.”  The “Prayer of the Imposition of hands” is then pronounced over them by the Bishop.
