I thought I'd take a look at the PDF about Lewis...and right away I saw that this wasn't Lewis "in his own words" but rather a series of quotes of Lewis', lifted out of their contexts and then skewered by the authors, as well as a number of quotes of what others had to say about Lewis.
Since I've read many of Lewis' works, I'm familiar with some of the quotes that were listed. For instance this particular quote from the Screwtape Letters:
God "often makes prizes of humans who have given their lives for causes He thinks bad on the monstrously sophistical ground that the humans thought them good and were following the best they knew"....
The fuller context of the quote is WWII and how many in the war took up the "cause", these would be both English and German, Christians on both sides of the fence...we can compare this to those Christians who fought in the Civil War for both the North and the South...each side thought their "cause" was right...at least one side (if not both sometimes) can be wrong...and yet God will make "prizes" of them anyway because in their own mind they were not willfully sinning against Him, in their error they thought they were doing the "right" thing. God is not going to deny a believer eternal life just because he fought for Germany in WWII or the South in the Civil war....
There is also this quote that the PDF points out as Lewis' "false teaching"
"There are three things that spread the Christ-life to us: baptism, belief, and that mysterious action which different Christians call by different names -- Holy Communion, the Mass, the Lord's Supper" (From Mere Christianity)
The authors of the PDF point to this as "proof" that Lewis taught a "salvation by works".
But again, the fuller context of the quote is this:
Now the God who arranged that process is the same God who arranges how the new kind of life—the Christ life—is to be spread. We must be prepared for it being odd too. He did not consult us when He invented sex: He has not consulted us either when He invented this.
There are three things that spread the Christ life to us: baptism, belief, and that mysterious action which different Christians call by different names—Holy Communion, the Mass, the Lord's Supper. At least, those are the three ordinary methods. I am not saying there may not be special cases where it is spread without one or more of these. I have not time to go into special cases, and I do not know enough. If you are trying in a few minutes to tell a man how to get to Edinburgh you will tell him the trains: he can, it is true, get there by boat or by a plane, but you will hardly bring that in. And I am not saying anything about which of these three things is the most essential. My Methodist friend would like me to say more about belief and less (in proportion) about the other two. But I am not going into that. Anyone who professes to teach you Christian doctrine will, in fact, tell you to use all three, and that is enough for our present purpose. (Mere Christianity)
What Lewis is getting at in this passage of Mere Christianity is that the new life we have in Christ is "spread" or grows in us via belief, baptism and communion. These three things are what all Christians have in common and he is entirely correct in this. If I know of a believer who constantly refuses baptism or communion, I would question his "belief". If I know of someone who is baptised, and yet believes that Jesus is in no way God, then I would question the baptism...
Lewis goes on to say:
I cannot myself see why these things should be the conductors of the new kind of life. But then, if one did not happen to know, I should never have seen any connection between a particular physical pleasure and the appearance of a new human being in the world. We have to take reality as it comes to us: there is no good jabbering about what it ought to be like or what we should have expected it to be like. But though I cannot see why it should be so, I can tell you why I believe it is so. I have explained why I have to believe that Jesus was (and is) God. And it seems plain as a matter of history that He taught His followers that the new life was communicated in this way.
In other words, I believe it on His authority. (Mere Christianity)
Again, Lewis wasn't defining the "exact moment of salvation" or anything like it...he was explaining essentials of Christian life and growth...and baptism and communion are most definitely part of essential life and growth, every bit as much as belief is. Demons believe, they are not baptized nor take communion.
I was reading through the PDF further and was just so overwhelmed by the misquotes, the taking things out of context and the innuendos in it...then I got to the part about Lewis promoting pedophilia (yes, pedophilia, child sexual abuse) in the scenes in Narnia between Lucy and Mr. Tumnus.
That's when I stopped reading. There is only so much gossip and lies I'm willing to stomach about a fellow brother in Christ.
I took a look at the others on the "Wolf List" ...I believe some are false teachers, I believe some are solid biblical teachers. But I do believe that the true "wolf" here may very well be Stewart himself.
