§ 1.  The Creed.  The ancient Creed which was used by the Church of Jerusalem in the middle of the fourth Century, and which Cyril expounded in his Catechetical Lectures, was recited by him to the Catechumens at the end of the fifth Lecture, to be committed to memory, but not to be written out on paper (§ 12).  Accordingly it is not found in any of the MSS., but instead of it the Nicene Creed with the Anathema is there inserted in Codd. Roe, Casaub.  This could only have been added after Cyril’s time, when the motives for secrecy had ceased.
