Children are in a different situation than adults. Children can’t choose their parents or determine their parents’ actions.
For adults, these are the signs that someone is ready to move from the period of inquiry to the catechumenate (from RCIA 42):
An initial conversion and intention to change their lives and to enter into a relationship with God in Christ; there must be evidence of the first stirrings of repentance, a start to the practice of calling upon God in prayer, a sense of the Church, and some experience of the company and spirit of Christians through contact with a priest or with members of the community.
The catechumenate, which is to last at least a year, then prepares the adults so that they show these signs that they are ready for baptism (from RCIA 75):
- A suitable catechesis is provided.
- The catechumens learn to turn more readily to God in prayer, bear witness to the faith, keep their hopes set on Christ, follow supernatural inspiration in their deeds, and practice love of neighbor, even at the cost of self-renunciation.
- Through liturgical rites they are strengthened by God’s blessing.
- Catechumens learn how to work actively with others to spread the Gospel and build up the Church by the witness of their lives and by professing their faith.
The Church holds adults to a pretty high standard before she considers them ready for baptism.
