Only one thing that really counts- the unwillingness of the Reformed/Protestant to abandon Scripture (rightly interpreted via the agency of the Holy Spirit) for the sake of mysticism (a la Catholicism) / spiritualism (a la Pentecostalism) and individualism (a la the emergent heresy).
In other words, what makes one a Reformed Christian or a Protestant Christian is one’s adherence to Sola Scriptura as the one central and abiding characteristic of Christian faith and practice. Catholics abandon sola scriptura in favor of tradition; Pentecostals abandon sola scriptura in favor of the ‘inner light’; and emergents abandon sola scriptura in favor of their own self interests and selfish motives.
One cannot be either Reformed or Protestant (in their various manifestations: Baptist, Methodist, Presbyterian, etc) without clinging to Scripture as the ONLY source of doctrine and the only wellspring of practice and devotion. The abandonment of Scripture is the open door to error in both faith and practice. And this is precisely why those who are truly Reformed and truly Protestant cannot become, even in small measure, Catholic, Pentecostal, or Emergent. Such would be a betrayal of the faith.
