Book excerpt: This book deals with the problem of Pentecostal 'traditioning'. Traditioning has been ineffective thus far because the richness of Pentecostal faith and experience has been inadequately captured in the classical Pentecostal doctrines of Spirit-baptism and glossolalia. A more adequate understanding of the key theological symbol of Pentecostalism, glossolalia, emerges when it is interpreted in the light of Christian spiritual tradition. Within this larger tradition glossolalia can be seen as bringing together both the ascetical and contemplative dimensions of the Christian life. Chan thus explores the shape of Pentecostal ecclesiology as 'traditioning community'.
