"Enthrall" as a verb also mean "enslave"--while missionaries have often paved the way for colonists who enslaved the natives, the example sentence does not connect to that definition. "Enthralled" as an emotion of wonder and delight contrasts with "derisive laughter"--both of which emphasize Achebe's view that outsiders who bring new ideas can face opposition as well as touch hearts, minds, and souls. This largely depends on whether they are more like Mr. Smith or Mr. Brown.
The interpreter explained each verse to the audience, some of whom now stood enthralled.
The hymn about brothers who sat in darkness and in fear seemed to answer a vague and persistent question that haunted his young soul—the question of the twins crying in the bush and the question of Ikemefuna who was killed.
Another definition of "impudent" is "marked by casual disrespect"--this would also fit the villagers' view of the missionaries for referring to the Ibo gods as wood and stone. But the example sentence is focused on the missionaries being so bold as to first ask for land and then to build on the Evil Forest, which the Ibos believe would be the missionaries' doom at the hands of the gods, ancestors, sinister forces, powers of darkness, and diseases.
And so excitement mounted in the village as the seventh week approached since the impudent missionaries built their church in the Evil Forest.
Suppose when he died all his male children decided to follow Nwoye's steps and abandon their ancestors? Okonkwo felt a cold shudder run through him at the terrible prospect, like the prospect of annihilation.
the act of atoning for sin or wrongdoing (especially appeasing a deity)
If a clansman killed a royal python accidentally, he made sacrifices of atonement and performed an expensive burial ceremony such as was done for a great man. No punishment was prescribed for a man who killed the python knowingly. Nobody thought that such a thing could ever happen.
(anthropology) relatedness or connection by blood or marriage or adoption
Another definition of "kinship" is "a close connection marked by community of interests"--this fits the example sentence's mention of "one voice." However, for the Ibos, kinship needs both definitions, while the Christians are challenging that idea by only requiring the second.
But I fear for you young people because you do not understand how strong is the bond of kinship. You do not know what it is to speak with one voice.
