From an interview with the Catholic Herald, December 1978:
“Methodism isn’t just a religion for Sundays—no faith is only a faith for Sundays. There were a lot of things during the week which one attended. Methodism is a pretty practical faith; there were the mothers’ sewing meetings and the guilds for young people.” . . .
Although she was married to Denis Thatcher 27 years ago in Wesley’s own chapel in the City of London, she has since moved towards Anglicanism and I asked her about this shift.
“You know, John Wesley would of course say that he was a member of the Church of England, and the service he believed in was the Church of England service; but it was too high for the kind of evangelical work he was doing.
“Methodism is the most marvellous evangelical faith and there is the most marvellous love and feeling for music in the Methodist Church which I think is greater than in the Anglican Church. But you sometimes feel the need for a slightly more formal service and perhaps a little bit more formality in the underlying theology too.
“So throughout my life I have felt the need for both things, to some extent for the informality, for the works you do; but always I found myself groping out for more of the actual teaching of the religious basis. As I say, I went for something a little more formal. I suppose it’s first one’s belief and then one’s background.”
She denies that this move was in any way a rebellion. The need for the formal and the evangelical came to rest for her in the Church of England, “but not the real High Church”, she adds.
