''Pat told me how God made you rich in character. You’re the mighty oak that holds the household together.''
1) You may think that the expression ''in character'' can only have the meaning of ''consistent with the traits or characteristics assigned to the character that one plays'', as in ''Dad is just in character - he is pretending to be a bad man for his movie!''. HOWEVER, in the sentence ''Pat told me how God made you rich in character'', the expression 'in character' is used to convey another different meaning, which is 'typical of one's behaviour' / 'consistent with someone's general personality or behaviour.' For example:
- ''Her failure to answer the invitation was completely in character.''
- ''For him to shout that way wasn't at all in character. He's usually quite pleasant.''
So, it means that the person has such a strong personality (maybe they are ''selfish'' or ''demanding'' or even ''extremely polite'') that their wealthiness befits them quite perfectly.
* [This usage dates from the mid-1700s, as does the antonym, 'out of character', as in ''It was out of character for him to refuse the assignment''.]
2) ''Mighty oak'': Firstly you should know that if you break down this expression, you shall have 'mighty' which means 'powerful/strong', and 'oak', which refers to 'any of numerous trees that bear acorns and often have leaves that are irregularly notched or lobed'. HOWEVER, in this case, the expression 'mighty oak' is being used figuratively to convey the idea that 'you are the pillar/power/strength that keeps your family together.'
Hope that helps!!!
