Why is the Catholic Church cannibalising the Book of Common Prayer?

From The Telegraph-

I’ve always felt sympathetic to foreigners on holiday in England who come across a church advertising Mass and displaying crucifixes and statues inside. When they discover later that they have been at a service of the Church of England, not of the Roman Catholic Church, they are puzzled and confused.

So what would you think if you went into a church and heard the clergyman begin: “God, unto whom all hearts be open, all desires known, and from whom no secrets are hid; cleanse the thoughts of our hearts by the inspiration of thy Holy Spirit…”?

If you said it was an early part of the Anglican service of Holy Communion, you’d be right. But I’ve just been looking at a new service booklet with the Order of Mass according to the Use of the Ordinariate. It begins with that prayer, yet it is a Roman Catholic liturgy. Instead of bells-and-smells Anglicans stealing the Catholics’ clothes, as it were, we have Catholics (Roman Catholics) cannibalising the Book of Common Prayer.
