A Christian Witness to the (Original) Negative Interpretation of the 'Fisher of Souls'

I have been developing an understanding of what the original Marcionite context of the gospel narrative was. I showed that the identification of many of the disciples as 'fishermen' would have had a negative association - i.e. with Satan, the original 'hunter of souls' (there is no separate Aramaic word for 'fisherman'). Here is an example of this understanding from within Christianity - the Nag Hammadi text the Authoritative Teaching:

For this reason, then, we do not sleep, nor do we forget the nets that are spread out in hiding, lying in wait for us to catch us. For if we are caught in a single net, it will suck us down into its mouth, while the water flows over us, striking our face. And we will be taken down into the dragnet, and we will not be able to come up from it, because the waters are high over us, flowing from above downward, submerging our heart down in the filthy mud. And we will not be able to escape from them. For man-eaters will seize us and swallow us, rejoicing like a fisherman casting a hook into the water. For he casts many kinds of food into the water because each one of the fish has his own food. He smells it and pursues its odor. But when he eats it, the hook hidden within the food seizes him and brings him up by force out of the deep waters. No man is able, then, to catch that fish down in the deep waters, except for the trap that the fisherman sets. By the ruse of food he brought the fish up on the hook.

In this very way we exist in this world, like fish. The adversary spies on us, lying in wait for us like a fisherman, wishing to seize us, rejoicing that he might swallow us. For he places many foods before our eyes (things) which belong to this world. He wishes to make us desire one of them and to taste only a little, so that he may seize us with his hidden poison and bring us out of freedom and take us into slavery. For whenever he catches us with a single food, it is indeed necessary for us to desire the rest. Finally, then, such things become the food of death.

Now these are the foods with which the devil lies in wait for us. First he injects a pain into your heart until you have heartache on account of a small thing of this life, and he seizes (you) with his poisons. And afterward (he injects) the desire of a tunic, so that you will pride yourself in it, and love of money, pride, vanity, envy that rivals another envy, beauty of body, fraudulence. The greatest of all these are ignorance and ease.

Now all such things the adversary prepares beautifully and spreads out before the body, wishing to make the mind of the soul incline her toward one of them and overwhelm her, like a hook, drawing her by force in ignorance, deceiving her until she conceives evil, and bears fruit of matter, and conducts herself in uncleanness, pursuing many desires, covetousnesses, while fleshly pleasure draws her in ignorance.
