The Problem of Wineskins foresaw many of the issues the church would to face. It highlighted the critical issues relating to the church's primary expressions and forms (wineskins). It gently questioned our understanding of discipleship, ecclesiology, Trinitarian theology, and the social implications of the gospel of Jesus Christ. This 40th Anniversary edition of The Problem of Wineskins offers the opportunity for Snyder's simple message to be read again at a time when it is even more needed than before. May we listen afresh and discern a birthing of new faithfulness for the church in mission for the twenty-first century.
