Faith in Jesus should produce in His followers a natural love toward others and a desire for unity within the body of Christ. Sadly, heated debate over the baptism of the Holy Spirit has often threatened that unity, resulting in unloving dismissals and accusations on differing sides. Situating the conversation within the context of brothers and sisters in dialogue, One Lord, One Faith, One Baptism offers a historical theology of the doctrine of Baptism in the Holy Spirit via a critical analysis of the history of denominationalism. Additionally, the volume constructs a biblical theology of "Spirit Baptism," that paves the way forward for healing the legacy of a divided church-healing enveloped by love, generosity, and unity within the family of God.
