Stanley Fish: Gladly Mixing

At the end of my edition of Paradise Lost, there are criticisms. Stanley Fish's criticism in the book (p. 498) falls under the category of christian ideology. His article is about Abdiel, "the zealous loyalist", a character Milton creates "more or less out of whole cloth that he can even imagine what it would be like not to feel the stirrings he describes as 'that last infirmity of Noble mind'." Stanley Fish goes on to explain how Abdiel is seen as visibly heroic because he was the only fallen angel who decided to remain faithful to God and drop Satan. Stanley Fish goes on to describe the way in which Abdiel takes flight from Satan: "All night the dreadless Angel unpursu'd / Through Heav'n's wide Champaign held his way, till Morn, / Wak't by the circling Hours, with rosy hand / Unbarr'd the gates of Light (PL, VI, 1-4). Staney goes on to say that the effect of this image is "to further undercut the urgency and point of Abdiel's linear flight." Stanley goes on to say how God is basically telling him "Good job at being Abdiel, Abdiel." He says that Abidel is what he is, does what he does, and is the servant of God. Staney Fish goes on to talk about Milton and questions what Miltn conceives of himself--his idenity, faith, etc. Stanley Fish ends his criticism with a long question having to do with what Milton' goal is and questions whether or not Milton wants to fail/fall and wander.
Stanley Fishs' criticism kind of confused me. From the introduction, i thought that his criticism was going to be on Abdiel. Most of it was with quotes reflecting Abdiel's flight from Hell to Heaven and God congradulatin him for choosing the good side and remaining faithful to him. The part that confused me was the title of this article is "gladly mixing" and the only thing Fish says that attains to this is: "Abdiel would have been glad to report and he just as gladly mixes--that is, loses himself in a host already composed without his reportorial aid." Maybe this means Abdiel did not report the informaion Satan wanted him to? Or Abdiel is mixed up between Satan and God? Whatever it may mean, I am glad that Stanley Fish recognizes Abdiel because Abdiel was the only one to remain faithful to God. Althought Stanley's article was a bit confusing, overall it was interesting to read.
