My understanding is that St Paul also advocated this practice in the NT, and hence the arguments about it being an OT law that was no longer required in the new covenant should be moot (for Paul would not advocate a law that did not still apply - I would think).
Paul was advocating a law that he believed still needed to be applied to the women of the 1st century church.
When you read 1 Corinthians 11, several things come to light. First and foremost, that Paul is not talking culturally, because he is talking to the church at Corinth, a church that was comprised of a variety of different cultures, and religious beliefs prior to conversion. the members of Corinth are coming from all walks of life, and from all different backgrounds.
Next, you find that Paul advocates a head covering, but then later explains that nature has provided a head covering in the form of long hair. Women who wear their hair long do not need to wear a covering, but women with short hair, scripturally, still should.
The OT law does not prescribe hair length as an option. In the OT, they wore veils.
and hence the arguments about it being an OT law that was no longer required in the new covenant should be moot
Even if you ignore the abrogation of the old law in the New Testament, the disregard for Jewish law and custom was immediate in the church. The struggle resulted in the Ebionite heresy. The movement however, never reflected a large portion of Christianity and was not long lived. From then on, I can think of no theologian who has ever suggested that Christians are still bound by the old law. The confusion now is not among theologians, but among adherents who are unaware of the theological stands of the bodies of which they are apart.
Again, no modern Christian body that I know of still holds that the Law is binding on Christians.As for a consensus among theologians there has never been one. There wasn\'t a perfect consensus between Peter and Paul, Paul and Barnabas, and on and on. There have however been consistent themes and stances of the church that have not faltered either at all or not until these modern times. So while perfect consensus may not exist, the official stance of the church (by that I mean every movement of any popular force) was, for nearly 1,600 years that all Christians must be baptized. The unbroken stance of the church has been that Christians do not get abortions. And so on...
No perfect consensus exists, but there are long standing, biblically supported stances which may be considered to have the general consensus of Christians now and in history.
This actually dates back to the compilation of the Bible with the Arian controversy - just look up Arianism and you will find Arius had a following before and after the compilation of the Bible and that his views were part of Christianity (until some sections decided to outlaw them).
Your first statement, that biblical scholars began disputing with Arius is seriously flawed. Theologians began disputing with Paul and Peter. The Bible itself records disputes between the two great apostles. Furthermore, you need to lose the idea that Arianism was some new shockwave to hit the church. Many more serious heresies preceded it. In the middle and late second century, two critical heresies would arise, Montanism and Marcionism. It should be noted that Montanism lasted longer than Arianism did as a major movement in the world. Biblical theologians debated over that. They debated over Sabellianism, which is the opposite of Arianism (though to be accurate, Arianism is the opposite of Sabellianism since the later predates the former by some 150 years). They debated over Monarchianism, Gnosticism, Adoptionism, and Dontaism (which also greatly outlasted Arianism) all before Arius was even a twinkle in his parents eye.
Second, your view of the development of the Bible is sadly two dimensional. It wasn\'t Arianism, but the aforementioned Marcionism that led to the development of the canon. Marcion is the first theologian we know of to declare what constituted the Bible. His bible had a \"butchered\" (to steal Tertullian\'s word) version of Luke and a selection of Pauline epistles in it. It was this rejection of documents key in traditional Christianity that led to \"orthodox\" Christians beginning to formulate the canon. Beginning with Justin Martyr and his disciple Tatian we see the orthodox acceptance of the four gospels and their theological defense of them. As early as 170, there are attempts at Christians to formulate a counter creed to correct Marcion. By the time of Origen, there is a basic consensus on the 27 books of the New Testament. He not only lists them but commentates on authorship and the validity of their general acceptance. You have the same books being used in Rome, North Africa, Alexandria, Antioch, and Gaul with the only exceptions being Revelation and Hebrews which were still contested in places (one or the other, depending on the region). Again, all of this is long before Arius.
Finally, the idea that some sections of Christianity outlawed Arius is ludicrous. The largest of the ecumenical councils of bishops gathered together to outlaw him not very long after his ideas appeared. While Arianism persisted, it wasn\'t because it found great acceptance until the ruthless Nicenes forced them out. You\'ll find that bishops and episcopal legates are deposed, tortured, brought up on false charges, and even murdered by the Arians trying to secure their position. Sozomenus, an ancient church historian, records an incident where the Arian emperor burned a boat in the harbor with 40 Nicenes aboard rather than hear their case.
That is one interpretation.
Jesus also said \'Faith without works is dead\' - which my Christian colleagues tell me means that if one has faith one obeys the laws of God. Therefore Christians still follow the laws of God, and Jesus said he did not come to change the law.
It is actually the only interpretation offered by theologians. You are simply proof texting and real theology requires more than that.
