But he could not bring himself to throw over the narrative of his party pamphlet (Book II.), and it remains much as it was originally written, though new touches were added.
The point to be made in public and in the apologetic tract was that the Reformers contemplated no alteration of "Authority." This was untrue.
Writing later (probably in 1565-66) in his Third Book, Knox boasts of his own initiation of the appeal to England, which included a scheme for the marriage of the Earl of Arran, son of the Hamilton chief, Chatelherault, to Queen Elizabeth.

Failing issue of Queen Mary, Arran was heir to the Scottish throne, and if he married the Queen of England, the rightful Queen of Scotland would not be likely to wear her crown.

The contemplated match was apt to involve a change of dynasty.

The lure of the crown for his descendants was likely to bring Chatelherault, and perhaps even his brother the Archbishop, over to the side of the Congregation: in short it was an excellent plot.

Probably the idea occurred to the leaders of the Congregation at or shortly after the time when Argyll and Lord James threw in their lot definitely with the brethren on May 31.
