A Religious Experience was a First Doctor comic story.
The First Doctor and Ian are enjoying an evening stroll along the beach on the planet Seetar in the Malachi System, when they are approached by a group of savages. A giant worm-like creature emerges from the sand and the savages begin to worship it. The worm appears ready to eat one of the natives but Ian intervenes distracting it with his torch and blinding the creature by throwing a cricket ball into its eyestalk.
Following their defeat of the creature the natives begin a celebration in the travellers honour. They are offered fruit and the savages prepare a human sacrifice. Ian prevents this sacrifice and they quickly return to the TARDIS where Barbara and Vicki are waiting. They wonder whether they will have had any lasting influence on the culture.
Many years later the Seventh Doctor arrives on the planet to find that human sacrifice has continued and they worship images of his former self, Ian and the TARDIS. The Doctor makes clear that it is time for these sacrifices to finally come to an end.
