My first thought was: that's never a prayer from the 17th century; it's much too modern. But then I realised that it's only the words and style that have changed over the centuries; the sentiments and attitudes described are probably just as applicable to women in every century. And men come to that.
I can relate to some of her words and I can certainly think of at least one person who would benefit from being kept from 'the fatal habit of thinking I must say something on every subject and on every occasion.' And who could do with learning 'the glorious lesson that occasionally I may be mistaken.'
And who would probably think the same about me.
