Who asked the question? And was it the PM's answer you want to know? All I can tell you is that Mrs May is a Christian who regularly attends church and her father was an Anglican vicar.
The link below is for PMQ's Wednesday 16 November 2016.
Not clear from your question whether the Prime Minister, Theresa May, was asked why Christians don't RECEIVE the same respect (as they used to) or don't GIVE the same respect (to government?)
I don't follow the Question Time on the BBC but they do catch-up systems for that, so if you go on to the BBC Parliament Today channel and do catch-up for that, you should get it. Sorry I can't help, as I didn't hear it.
