This is my first year as an RCIA instructor. The folks I work with are seniors who are free for the first time in their lives to pursue their desire to join the Church.
SuscipeMeDomine hit the nail on the head when they said,
The very first thing I would steer you away from is the idea of “teaching” RCIA. It’s not a class.
In Youth Formation, the teacher asks the children questions about things they haven’t thought about yet. But adults, particularly older adults have their own questions, many stemming from a relationship with Christ that has already begun with a call to Him. We facilitate and enable them to find their answers in Scripture and Church teaching, but most of in prayer.
That doesn’t mean there is no place for a curriculum. You just can’t approach older people from a didactic stance like you would a child who has limited life experience. What a curriculum can do is prepare you to address the questions catechumens and candidates have when they ask them. It also gives you topics of discussion to bring up so you can make sure they get everything they need.
The Catechism of the Church is a compendium. It is a well constructed curriculum itself, but it was designed for a lifetime. (To make an 81 or 93 year old wait 3-7yrs to complete a course of study in order to receive the Sacraments of initiation is obscene.) The content of this journey must give them what they need to receive the Lord, yet show them how to use prayer, sacraments, Revelation to keep growing in His love.
The priest will be playing a crucial role in RCIA than Youth formation. Children receive an introduction to prayer but these adults,
must developed a solid spiritual life. Effective Catechisis must be part study group and part spiritual direction/pastoral care. Otherwise, there’s a risk that they are going to become the statistic that 1 out of 3 catechumens will no longer practice after 3 years in the Church.
Finally, don’t neglect your own spiritual life. Teaching prayer is not praying. It’s too easy to get lost in everything that has to be done, especially around Easter Vigil when the most important thing is to join the Church in rejoicing in the Resurrection.
