In All in the Name, Mark tells his story first of trading his conventional Baptist upbringing for the emotional buzz and fiery preaching of Oneness Pentecostal worship, and for the thrill of thinking that he was among an elite group of believers who followed the true faith where so many others had strayed. His experience echoes that of many other Christians who are leaving orthodox Christianity for a growing movement that claims:
-Speaking in tongues is a necessary sign of receiving the Holy Spirit and thus a condition for salvation;
-Only those baptized "in the name of Jesus"not "in the name of the Father, and of the Son, and of the Holy Spirit" are true Christians;
-Jesus is not the eternal Son of God but rather the Father manifested on earth
But an inquisitive mind, careful study, and the action of the Holy Spirit finally led Mark out of Oneness Pentecostalism and into the Catholic Church. A faith-strengthener for Catholics and an intriguing challenge to those who reject the Trinity.
