What was their textual or scriptural justification for this "Catholic-Lite" approach? Then we can move on to the Lutherans and Calvinists.
Hi
So I can understand the perception that Anglicanism is 'Catholicism-Lite' but this isn't quite the reality. Anglicanism is the result of what folks at the time actually wanted to happen: a reformation within the Catholic Church. It's important to understand here how the Anglican Church views itself: it sees itself as
the holy, catholic, apostolic Church. The Catholic Church as the Catholic Church is meant to be. So, in short, they took out the bits of Catholicism they found problematic or in their view lacking authority, and kept the rest. So they needed no justification for this, they already believed the Catholic Church was the true Church, but it needed taking back to how it should have been, i.e., reforming. They weren't trying to form a totally separate, breakaway Church that saw itself as kind of restarting.
I also would like to interject here that the Anglican Church is not a
Sola Scriptura Church; this is a mistaken understanding; the AC is
Prima Scriptura, i.e., scriptural primacy, but without neglecting other avenues as well. The Anglican approach to this is commonly pictured as a 3 legged stool: Scripture, Tradition and Reason:
“Properly interpreted and subordinated to Scripture and reason, therefore, tradition takes its rightful place as the consensus based upon long usage or acceptance within the Christian community.”
It's also important to note that the English were not Protestants, by and large, they just wanted to see changes
within the CC. The Protestant movement in England was an elite movement, from the top-down, a political movement not a grassroots religious one. Even history scholars such as David Starkey will tell you that the English were not Protestants and never had any huge revolution or demand for a Protestant church, and many of them were in fact hardcore Catholics, which led to things such as this
Pilgrimage of Grace - Wikipedia. There were small pockets of Protestants, but nothing like what one would have seen in Germany. This being the case, when Queen Elizabeth finally settled the religious question it's called 'The English Religious Settlement', as there were far too many Catholics for the kinds of things one was seeing on the continent. During this Settlement, changes were actually made to accommodate Catholics, such as within the Book of Common Prayer, and freedom of belief for things like Holy Communion (Real Presence) etc.
"The settlement of 1559 had given Protestants control of the Church of England, but matters were different at the parish level, where Catholic priests and traditional laity held large majorities. The bishops struggled for decades to impose the Prayer Book and Injunctions on reluctant parishes. "For a while, it was possible to sustain an attenuated Catholicism within the parish framework, by counterfeiting the mass, teaching the seven sacraments, preserving images of saints, reciting the rosary, observing feasts, fasts, and customs."
So the short of it is, the AC sees itself as the true Catholic Church, and the RCC as having bastardised itself with superstition, which the Anglicans have righted.
