At Antioch, the Catechizing preceded the Exorcism, as we learn from S. Chrysostom:  “After you have heard our instruction, they take off your sandals, and unclothe you, and send you on naked and barefoot, with your tunic only, to the utterances of the Exorcists Ad Illuminandos, Cat. i. § 2..”  Cyril says nothing of this unclothing, but mentions another ceremony as practised at Jerusalem:  “Thy face has been veiled, that thy mind may henceforward be free, lest the eye by roving make the heart rove also.  But when thine eyes are veiled, thine ears are not hindered from receiving the means of salvation Procat. § 9..”  The veil may also have been a symbol of the slavery and darkness of sin, as S. Augustine regards the removal of the veil on the octave of Easter as symbolising the spiritual liberty of the baptized S. Aug. Serm. 376.  “Hodie octavæ dicuntur Infantium; revelanda sunt capita eorum, quod est indicium libertatis.  Habet enim libertatem ista spiritualis nativitas, propriæ autem carnis nativitas servitutem.”.  Of this meaning Cyril makes no express mention.
