There are more than 260 direct quotations of the Old Testament in the 27 books of the New testament meaning the average Gospel or Epistle (Revelation included) cites the OT more than nine times each. Since some books are really short, the average is actually quite a bit higher. Jesus cites the OT as the ultimate authority even saying that not even the smallest little mark made in the OT would cease until heaven and earth pass away. So, I'm not sure why quoting the OT is out of bounds for a Christian. I am staring to think you might be confused by what it means to be a Christian however. Paul definitively states that there is not one righteous person - not even one and all fall short of God's perfect expectations. A Christian is one who abandons any sense or hope that he can attain to the righteousness of God of his own doing but instead accepts that 100% of the righteousness needed to be accepted by God will come from what Christ did on the cross. Not 50%/50%, not 1%/99%, not .000000001%/99.99999999%, but 0.00%/100% of His righteousness and not mine. That's what it means to be a "Christian".
Now a windfall is defined a sudden and unexpected gain without merit. There is no west pilot who suddenly and unexpectedly gained as a result of the SLI produced by the NIC. If it had been adopted in 2007 when it was released there would have been little to no movement at all. The east, and you in particular, want to look at 6 or more years of delay and say this if the NIC took effect now that there would be more movement than there would have been six years ago. That may well be true, but it would not be sudden (award issued in 2007) or unexpected (west pilots just like east pilots had an expectation to be able to move to the left seat when their relative position on the seniority list allowed for it). So there is no windfall. The both pilot groups were slotted in to a larger, integrated list and that was a direct result, good or bad, of the merger that was initiated on 9/27/2005; an event that created benefits and costs to both east and west pilots. Now which group is unwilling to accept the costs that come with the merger?
