I agree that it would be
interesting for the OP to provide some citations for this, however, apart from that I am 99% sure that one could find examples where something has been defined as a “sin” in one era, and not another, and the some good people have advanced civilization by obeying God first, and done something regarded as “sinful” at the time.
It’s not something I can readily support, apart from the example I provided in my first post of St Mary McKillop, who disobeyed her bishop (a “sin” of disobedience) and was excommunicated. Someone else mentioned that his or her parents were told that it would be a “mortal sin” to not send the child to a Catholic school - but did anyway. In times past, Catholics read and used books which were on The Index of Forbidden Books and scientific progress was made.
These were (apparent) “sins” of disobedience, rather than against the God’s law. Whether we can find more fundamental “sins” (defined, not actual) - I don’t know.
Hopefully the OP will provide some citations for his claim about women in sport.
I find this an interesting topic.
We are in universal agreement that one may not commit an actual sin (mortal or venial) in order for good to come from it. However I argue that one can, in conscience, disobey Church authority. It’s a big call - but sometimes it’s valid, and may even be necessary.
Another one that’s just come to mind. I recall that in the time of Queen Elizabeth of England the Pope ordered English Catholics to disobey Elizabeth and rise against her - and most didn’t. I don’t think there was any subsequent censure from the Church for their disobedience. There are probably other examples from the times when the Church was more involved in politics.
On the other hand, it would be helpful, very helpful, for the OP to give more information about his own example.
