The Initial Conversion is the “initial” turning away from sin and turning towards God. The Church uses the term “initial” because conversion is truly a lifelong process. When a youth experiences an initial conversion, it is because they are developing a personal interest and trust in God or possibly in someone in the Church. In short, they are beginning to have a special interest in a personal relationship with Jesus Christ and are beginning to make changes in their lives in order to begin this process.
In Forming Intentional Disciples, Sherry Weddell discusses five thresholds of conversions that one must go through before they are a conscious and intentional Disciple. With youth, no matter where they are at in these thresholds our goal is to continue feeding them what they need. So when a youth has an “initial conversion” we want to be ready to continue drawing them in and at some point asking them to make a commitment to enter into Discipleship, which means “dropping their nets” and following Christ with their whole lives.

Catechesis is that particular form of the ministry of the word which matures initial conversion to make it into a living, explicit and fruitful confession of faith. (GDC 82)
