Final answer:
According to the narrator, the Scylding hold heathen sacrifices instead of praying to the 'Almighty' because they believe in paganism, which involves the worship of multiple gods or nature spirits.
Step-by-step explanation:
The answer to the question is a) They believe in paganism.
The narrator indicates that the Scylding hold heathen sacrifices instead of praying to the 'Almighty' because they believe in paganism. Paganism refers to the worship of multiple gods or nature spirits, which is different from the monotheistic belief in one almighty deity. The Scylding's preference for heathen sacrifices suggests that they adhere to their traditional polytheistic faith rather than embracing Christianity.
For example, in the context provided, Christians regarded worshipers of other gods as 'pagans' and condemned their beliefs as ignorant and foolish. This demonstrates that there was a clear distinction between pagan and Christian beliefs during the time mentioned in the text.
