@Walter Hinteler,
It was the established church, Walter. One could not hold public office unless one was a communicant of the Anglican Church. If you were to dig a little deeper, you'd find that the Restoration Parliament also took steps to exclude those professing any other religion from public office. There were a series of Test Acts, beginning in 1673, and the first was intended specifically to target James, Duke of York, who was (correctly) believed to be a secret Catholic. The RC Church later gave dispensation for Catholics to take Anglican communion to get around the Test Acts, so in the reign of Queen Anne, the Parliament passed the Occasional Conformity Act. I do have to wonder how you would define "state religion."
