Hippolytus II v. Rom: RAC 15, 524-526, in which the catechumen audiens hears catechesis for three years cathecumeni per tres annos audiant, given by lay teachers didascali or clergy ch. 17, ed. Botte; V. Saxer, 221-232; prayer follows the catechesis. The context seems to be that of the morning liturgy of the Word, before work, with the faithful, but in a special room A.G. Martimort, TA: DS, fasc. 99101 1991 1136-1146. IV. Fourth and fifth centuries. With the Constantinian change and the peace of the church, the new Christian regime brought new pastoral problems. Catechumens, even children, were considered Christians by civil law H. Karpp, Christennamen: RAC 2, 1135; A. Stenzel, art. Kindertaufe: LTK2 160. Despite the urging of bishops, not a few, even those in Christian families, delayed baptism, not infrequently to the end of life clinical baptism: One desires not so much to be a Christian, as to feign being one Aug., De cat. rud. 5,9; It is not enough to be conceived, one must be born to reach eternal life Aug., Ad Simplic. 1,2,29. The ancient catechumenate disappears as a pastoral structure, yielding its place to a catechumenal status’ more or less definitive G. Groppo, Catecumenato antico: J. Gevaert ed., 135. Preparation for baptism was concentrated in a mini catechumenate of competentes = photizomenoi; at Rome: electi, or adult candidates, during Lent. The same external forms now hid different realities yet it is the golden age of catechesis M. Sachot, 161-163. Within the unity of the catechumenal way, a threefold catechesis developed: dogmatic, with commentary on the creed A. Sabugal, Io credo, passim and the Our Father Id., Il Padrenostro, passim; moral catechesis, the oldest one’s behavior is confronted with the Christian faith; mystagogical catechesis in Easter week, with explanation of the rites of the three sacraments received: baptism with laying on of hands, anointing or confirmation, Eucharist J. Danilou, La catechesi, 168- 184; Ch. Jacob, Arkandisziplin, Allegorese, Mystagogie. Ein neuer Zugang zur Theologie des A. v. Mailand: Theophaneia 32 1990 119-280. Rites multiplied, offering richer material to typology and mystagogy. A relation was established between mystagogical catechesis and the novelty of the creed: what mystagogy unveils in the rites, the creed expresses in words; typology predominates.
