Fair enough, though i find it can be helpful to identify where doctrine originate and how they trace through the history of the church by the men who present them. Satan may be the originator of the lie, but sometimes it's easier to recognize that it is a lie when we know who first proposed it and what their background is. I certainly don't fault Augustine, and think he was a truly devout man. But even devout men fall victim to falsehoods from time to time.
Not wanting to disagree with you, but...
I came to recognize lies, only after I studied the Bible.
For example, I came to realize that hellfire did not exist; the soul is not immortal; all good people do not go to heaven... and many other thing, and I did not know where they originated, or whom from, until after I appreciated that the Bible is truly God's word, and the source of truth.
It was then I realized how dangerous religion is, and why it's so important to consider what religious people teach, and match it with against the Bible.
To this day, I don't know half the teachings that are not scriptural, and who promotes them, but I know the truth, because it's easier to identify that from scripture.
It is true that some things are worth knowing, so as to avoid them, but these are mostly rituals, and customs.
Many people wear a cross on a chain, without knowing the origin, and how God views it.
I would agree it's helpful... in some cases, to know the background.
However, for the most part, I don't want to know who teaches falsehood, and where they originated, because when I talk to people about the Bible, I don't want to be focused on comparing religion, or religious people. I just want people to see what the Bible says. Then they will see for themselves who is teaching otherwise.
To give an example, I may be talking to someone about what the Bible says about, say, idols.
I don't know who I am talking to, but then I mention some religion by name, that promoted this teaching.
Lo and behold, without realizing it, I just put a wall between that person and the scriptures, because they are fervent worshippers of that religion, and so, rather than hear, or see what I am showing them, their emotions kick in, and they only hear "Your religion is wrong."
It's better they come to see that for themselves, by examining what the Bible says, than me telling them.
You get what I'm saying?
No pearl clutching from me, bud.
