It is true, and important to note, that the scriptural meaning of the word "perfect" may be different than the way we use it, just as the scriptural meaning of the word "pride" is different than the way we use it. If so, we need to seek out what the scriptural meaning is, so we can understand the text placed before us for our salvation.
But of this we can be sure: when our language disagrees with the scriptures than we must correct our language, not correct the scriptures.
If the scriptures say "nobody is perfect and God doesn't expect us to be" then let us stand by that statement even if we have to die for it. Let us resound that statement to the heavens if that be the case. And if the scriptures say something else, then let us stand by that with our very lives instead. And let us boldly declare that instead.
I will not comment further. I am simply going to quote, and quote, and quote. And you can decide for yourselves, and I will decide for myself, what to think of this matter.

33 And again, if ye by the grace of God are perfect in Christ, and deny not his power, then are ye sanctified in Christ by the grace of God, through the shedding of the blood of Christ, which is in the covenant of the father unto the remission of your sins, that ye become holy, without spot.

I quote here, as well, uses of a peculiar phrase used repeatedly in the scriptures. It is the phrase "just men made perfect". They are possibly similar in meaning to the quotation "for Noah was a just men, and perfect in his generation". Certainly they are "made perfect through Jesus the mediator of the new covenant", but I don't think that means that they are either twinkled into better men than they were or that they are merely made perfect in the sense that their wrong actions are excused, like a teacher giving someone 100% by intentionally skipping the questions he answered wrongly.
