one-step doctrine

[Dedicated Mind]

speaking of moving beyond "the principles of the doctrine", I'm all for that seeing I get bored with some the the redundancy of the forum, but I can't get this one-step doctrine out of my mind. I have never heard of apostolics teaching this doctrine until I came to this forum. I was always of the notion that apostolics believed in 3 steps, repentance, water and sprit baptism. If one-step doctrine is true, does that mean that many people from protestant and catholic denominations are saved?? I sympatize with one-step because many of my family members are trinitarian pentecostals and I hope for their salvation, but my mind still believes that Jesus-name baptism is still needed. I don't mean to rehash salvation doctrine, but I do wish that one-step were true and that many more would be saved.
