Historically, the church's ministry of grounding new believers in the essentials of the faith has been known as ''catechesis''--systematic instruction in faith foundations, including what we believe, how we pray and worship, and how we conduct our lives. For most evangelicals today, however, this very idea is an alien concept. Packer and Parrett, concerned for the state of the church, seek to inspire a much needed evangelical course correction. This new book makes the case for a recovery of significant catechesis as a nonnegotiable practice of churches, showing the practice to be complementary to, and of no less value than, Bible study, expository preaching, and other formational ministries, and urging evangelical churches to find room for this biblical ministry for the sake of their spiritual health and vitality.
