Criticism in academic circles: Thomas Cartwright (a cambridge professor) introduced presbyterian teaching into England in 1570, through a series of speeches; contrasted Elizabethan Church against early Church, arguing it didn't reflect biblica, he concluded bishops' role in Elizabeth's Church didn't reflect biblical practice; increased resentment against bishops due to clampdown on dissenting ministers and failure to lead 'true' reformation - so his freedom of speech was quickly removed along with his professorship
