"[H]e was a great admirer of Calvin, whose writings he regarded as one of the three pillars of the faith and worship of the reformed English Church, along with the Thirty-nine Articles and the Book of Common Prayer. All leaders of the Church, from John Jewel to John Whitgift, were in Calvin's debt, in Hooker's opinion. His quarrel was only with the Calvinist discipline and with the biblical extremism that some Puritans were trying to impose in England. The presbyterian polity might or might not be suitable for Geneva and other principalities, but here in England, Hooker believed, there was an existing ecclesiastical polity which conformed to the traditions and laws of his country."
