Elizabeth II has never been known as much of a Christian in terms of deep faith. She likes the pomp and circumstance of some Anglican ceremonies and is still officially the head of the Anglican Church - which in itself shows she’s not serious about Christianity. She pays lip service but refuses to stand up for Christian morals in any serious way.
She, and her family, are some of the greatest reasons for the failure of Anglican Christianity in the U.K. Millions of souls have been lost and she is partly responsible.
Given that she can never speak of these matters in public, save in the one Christmas message described in the article, I wonder how you (or anyone else) can know that?
but refuses to stand up for Christian morals in any serious way.
Again, how do you know, given that the only means constitutionally available to her to do so is in private advice to her ministers?
There is little she could do against the powerful tide of socialism after the devastation of WWI and WWII in her homeland, and the constraints placed on the monarch by Parliament since the time of Charles II. If she had fought vigorously, she risked ending the monarchy altogether.
I personally hope she had inveighed against her sons' disgusting episodes and abuses; my guess is that she did that privately, but they did as they pleased. Due to her duties as queen, her children were raised by nannies, and when the worldwide, so-called "sexual revolution" fueled by development of The Pill came along, her two oldest sons, her sister and to a certain extent her daughter were swept up in it. I see her as having steadfastly held the line in her example, in spite of the lock Parliament has on her actions.
As for "liking" the pomp and circumstance, who wouldn't? But to see her as superficially narcissistic, like Obama, with regard to ceremony, is a great misunderstanding. A flightier woman would have stepped down long ago and lived an alcoholic existence attended by gay courtiers like her mother and sister. Instead, she is continuing to perform public duties such as visiting the victims of disasters, attending church publicly with the press in attendance as she enters and leaves, reviewing the troops, and cutting ribbons at hospitals and schools—at age 91—and still does not let anyone touch her in public even to help her down a flight of stairs or into a car. She is keeping a vow she made at age 24. Few human beings possess her stamina.
