I don’t see it the way the priest narrating the video sees it’s either.
I see it the way you do and I didn’t see any immodest or inappropriate dancing or clothing and I don’t think her hugging a male judge was immodest.
The hug was not ‘sexual’ or done as man-woman romantic way- it was just natural human hug of joy and excitement.
Unfortunately some people will see immodesty and sexualness even in innocent things.
In a world at the height of singers with “boobs and bums” out,I think Sister Christina is being a beautiful witness to the world of Jesus and Christianity.
Her Like a Virgin version is about a nun being “touched” by the love of Jesus/God for the first time not by a man in a sexual way.
I think it’s meant to be very counterculture-ie:Madonnas ‘way’ leads to one path,and the Nuns way leads to another.
That’s how I see it anyway.
