I’ve been thinking about Lent and the early Christian practice of preparing catechumens for baptism at Easter. The word “catechumen” itself implies that teaching and learning were part of the process of preparation. The church taught the faith it had received and the catechumens learned. Catechesis is instruction.
Catechumens were also expected to put what they learned into practice. The so-called Apostolic Tradition once attributed to Hippolytus sets out this requirement.
When they are chosen who are to receive baptism, let their lives be examined, whether they have lived honorably while catechumens, whether they honored the widows, whether they visited the sick, and whether they have done every good work. (20:1)
Along with instruction, the church practiced prayer and fasting as a means of preparation. Circa 155 AD, Justin (called “The Martyr”) wrote this in his First Apology or defense of the Christian faith.
As many as are persuaded and believe that what we teach and say is true, and undertake to be able to live accordingly, are instructed to pray and to entreat God with fasting, for the remission of their sins that are past, we praying and fasting with them. Then they are brought by us where there is water, and are regenerated in the same manner in which we were ourselves regenerated.
The catechumens fasted and prayed for the remission of their sins, as did the church.
