Irrationalism crept into the pentecostals camp which in turn crept back into Rome

"By the end of [... World War 1] fundamentalism had moved from its scholarly form as defended by eminent theologians in the famous The Fundamentals and had become a very non-scholarly movement making progress among the less affluent population. My father was certainly among the less affluent population, as were his people; but there was only one member who took up with the new movement. That the Pentecostals accepted the five points of the original fundamentals, namely, the inerrancy of Scripture, the virgin birth, Jesus' miracles, his vicarious atonement and resurrection, admits of no doubt.
But let us remember that the Galatian Judaizers, whom Paul so vigoriously condemned, believed these five points too. What they did not believe was justification by faith alone. Did the early Pentecostals believe it? Do they believe and teach it now? Or is their developed view of tongues inconsistent with the evangelicals' historic position? However it may have been in the 1920's, more recently, beginning at the University of Notre Dame, the Pentecostals have penetrated Romanism and have welcomed numerous Catholics, if not into their assembly halls, certainly into their spiritual fellowship." - Gordon H.
