Studies show that children attending Sunday Schools and youth programs are less likely to continue church involvement, compared to those who attended worship with parents, and are integrated into a community (e.g., Mark de Vries "Family-Based Youth Ministry", 2004). Those children who continue church involvement as adults often have a ‘nominal faith’ (e.g. George Barna "Transforming children into Spiritual Champions", 2003). Proponents of this mode of ministry claim it is a Biblical model - particularly when the ministry is located within the family in accordance with the 'relational' Hebrew model described in Deuteronomy 6.
