Why was Okonkwo provoked to such great anger that he threatened to kill his son, Nwoye? How was Nwoye saved?

Part of the reason Okonkwo is so angry about Nwoye's new religion is that he considers Christianity weak and effeminate, He also happens to think that his son Nwoye is also weak and effeminate. Nwoye goes to the Christian church because of Okonkwo's abuse. This enrages Okonkwo. The church protects his son.
