Given that the change was made by some of the same men who wrote your New Testament, it seems rather silly to defer to them in print and not defer to their authority in person.
Then again your New Testament was canonized by a church which had been celebrating Easter and worshipping on Sunday for about three centuries, and that doesn't seem to bother you.
I seriously doubt any writers of the NT were alive when this change was made. It can't be proved one way or another. The scriptures are Gods Word to us. They don't belong to any one church. Yes God used your church to keep His Word "safe". Does that make you happy?
