Indeed, many who are drawn towards lines of thinking more in common with the Abrahamic traditions see The Beast of the Sea and Cthulhu as one and the same, Nyarlathotep the false prophet, Dagon the Leviathan, etc. (Though the name of Dagon itself is a loan from the philistines of old).It is not the names or actual appearances that matter, but rather what they symbolize and represent. 

Though of course in workings of ritual magick names do have meaning as words are to the spirits and gods as physical force is to us. Spirits and deities are shaped by their names and their inherent meaning within their respective traditions. Though these entities at the same time are not gods, persay. The King in yellow for instance is both entity and force. Entropy, spiritual decay, ruin, all of these are his domain, civilizations fall and crumble. All nations become Carcosa, all serve the King in Yellow in the end.
