Any thoughts?
I was thinking maybe a less stringent Act of Uniformity (1558). IOTL it fined everybody who didn't attend an Anglican service; ITTL maybe she could decide that this risks inciting rebellion, and instead the provisions only apply to the gentry (under the assumption that, if the gentry are all on-side, the peasants will follow, or at least be unable to cause any trouble). This might result in a situation a bit like Ireland IOTL, where the upper class are mostly Protestants and the lower classes are mostly Catholic.
