We’ve heard mention of the gods since season one. Does anyone else think that the gods in question are indeed the gods of Ancient Greece? It would seem so to me, especially with this half season’s arc of Hades being god of the UW and his brother Zeus being head god of Mount Olympus.
Merlin and his friend also mentioned “Gods”, when they found the Holy Grail.
Man: That’s a gift from the Gods.
Merlin: We are hardly worth notice of the Gods.
Man: The Gods could do worse. But if you don’t want any…
Notice how the didn’t say “God”, but the plural “Gods.” If by chance they were to further explain the Holy Grail, I could see the twist being that the Grail is connected to the Greek God Dionysus rather than Jesus. There have been many comparisons between Jesus and Dionysus, with the connection to wine being one of them. Here’s an example of this from Wikipedia:
Parallels have been drawn between Greek myths and the life of Jesus. An early example was Friedrich Hölderlin, who in his Brot und Wein (1800–1801) suggested similarities between the Greek god Dionysus and Jesus.
Modern scholars such as Martin Hengel, Barry Powell, and Peter Wick, among others, argue that Dionysian religion and Christianity have notable parallels. They point to the symbolism of wine and the importance it held in the mythology surrounding both Dionysus and Jesus Christ; although, Wick argues that the use of wine symbolism in the Gospel of John, including the story of the Marriage at Cana at which Jesus turns water into wine, was intended to show Jesus as superior to Dionysus.
Additionally, some scholars of comparative mythology argue that both Dionysus and Jesus represent the “dying-and-returning god” mythological archetype. Other parallels, such as the celebration by a ritual meal of bread and wine, have also been suggested and Powell, in particular, argues that precursors to the Christian notion of transubstantiation can be found in Dionysian religion. Another parallel has been drawn to how in the Bacchae Dionysus appears before King Pentheus on charges of claiming divinity and is compared to the New Testament scene of Jesus being interrogated by Pontius Pilate.
E. Kessler has argued that the Dionysian cult developed into strict monotheism by the 4th century CE; and together with Mithraism and other sects the cult formed an instance of “pagan monotheism” in direct competition with Early Christianity during Late Antiquity.

Not that I seriously expect OUAT to explore this, but I guess it is food for though regardless.
