Religious communities have an obvious interest in passing on their beliefs and practices to future generations. Many traditional churches, however, report major difficulties in retaining the interest and involvement of adolescents. This study seeks to explore attitudes to a key indicator of traditional practice, church attendance, amongst Australian core Catholic youth (14-15 years of age). Fifty-eight semi-structured interviews were conducted with adolescents with a pre-existing connection with parish communities. Most adolescents interviewed expressed either strong or weak familial pattern of church attendance and predicted a likely decrease in their future participation. This, coupled with the experience of older siblings' reported views about the significance of the Eucharist and a lack of supportive social networks either at school or in the wider community, suggests that many core Catholic adolescents are likely to become less involved in church life in the future.
