Hi Proudfather - I'm proud too!
I don't agree with your statement about "why are we suddenly confused" about the uncut hair issue. I noticed that the quote you shared from the NLT didn't even mention uncut hair.
Historically, this is really a "new issue" among Apostolics. The farthest back I've been able to even trace the teaching is a 1937 article by S.G. Norris. My own family, which traces Apostolic roots back to GT Haywood and Howard Goss' ministries didn't stop trimming their hair until the social upheavals of the 1960s' were taking place.
Holiness not only "matters," it is essential. Adding the "uncut hair" doctrine to the apostle's doctrine however, is not "holiness" - IMHO. It's a bit profane.
The Word of God and the teachings of the First Century apostles are something that is very HOLY to me. This is sacred ground. Let's not bring in the "sacred cows" and others beasts from the world to trammel the Holy Place.
