Personally I struggle with this too.
If the point of not lying is just for its own sake (ie:lying in itself is always wrong) then doesn’t this lead to like a fundamentalist mentality or even potentially neurosises with people playing “word games” to avoid telling a lie?
To me it would make more sense that lying should be wrong when or because it hurts someone or will affect them negatively.
Eg:a real estate agent who lied or withheld the truth to a potential house buyer that the place needed repairs and then “sealed the deal” while withholding that there were some repair issues.
That to me would be wrong because it would affect the person who bought the house negatively and under false premises.
I lie though sometimes about things that don’t affect negatively/hurt others though.
For example,when my elderly mother gives me a top or dress etc of hers and she will ask if I like it.
Sometimes I will lie and say yes,when it may not really be my style,because I know how much it means to her,I feel greatful that she cares about me,I know that she’s always liked fashion and wants to pass on something that means a lot to her/that she likes to me as her daughter,and I know that she isn’t the type of person that you can say to “thanks for thinking of me,but it’s not my style”.
Her feelings would be hurt,so is it really such a sin if I lie this way?
