Yes, Scottish Presbyterianism has its own genealogy, but English Presbyterianism (which was the entire context of my video) is in a real sense a daughter of Anglicanism. Anglicanism did not merely coexist with English Presbyterianism—it helped give birth to it. That is, Presbyterianism is not simply something that existed outside Anglicanism; historically, English Presbyterianism largely came out of the Church of England. Most of the Puritan Presbyterians were already ordained Church of England ministers. Westminster itself was largely an assembly of Church of England clergy, originally called to pursue a “further and more perfect Reformation” of the English church and, in the context of the Solemn League and Covenant, to bring greater unity and uniformity with the other Reformed churches of Britain. They were not initially trying to found a completely separate denomination—they were trying to reform the Church of England itself. Then, when the episcopal and Prayer Book settlement was restored in 1662, when, as you know, 2,000 Anglican ministers were ejected, it helped turn what had been an internal Anglican movement within the English church into Puritan and Presbyterian movement of non-conformity.
