Brideshead Revisited
Sebastian's family is Catholic.  His father, Lord Marchmain, had been an Anglican, but he had converted to Roman Catholicism, his wife's religion.  The family talk a lot about religion which surprises Charles, who had always thought that Christianity was not an important subject.  Lady Marchmain, Sebastian's mother, is a very strict Catholic.  She tries to control others by making them feel guilty. Sebastian finds comfort by drinking  alcohol.  He often gets drunk, and over a period of two years he has less and less to do with the Flyte family.
