These Bands were illegal.

A Band, says Knox, was now signed by Argyll, Lorne, Glencairn, Morton, and Erskine of Dun, and many others unknown, on December 3, 1557.

It is alleged that "Satan cruelly doth rage." Now, how was Satan raging in December 1557?
Myln, the last martyr, was not pursued till April 1558, by Knox's account.
The first godly Band being of December 1557, {80b} and drawn up, perhaps, on the impulse of Knox's severe letter from Dieppe of October 27, in that year; just after they signed the Band, what were the demands of the Banders?
They asked, apparently, that the Second Prayer Book of Edward VI.

should be read in all parish churches, with the Lessons: _if the curates are able to read_: if not, then by any qualified parishioner.
Secondly, preaching must be permitted in private houses, "without great conventions of the people." {81a} Whether the Catholic service was to be concurrently permitted does not appear; it is not very probable, for that service is idolatrous, and the Band itself denounces the Church as "the Congregation of Satan." Dr.M'Crie thinks that the Banders, or Congregation of God, did not ask for the universal adoption of the English Prayer Book, but only requested that they themselves might bring it in "in places to which their authority and influence extended." They took that liberty, certainly, without waiting for leave, but their demand appears to apply to all parish churches.

War, in fact, was denounced against Satan's Congregation; {81b} if it troubles the Lords' Congregation, there could therefore be little idea of tolerating their nefarious creed and ritual.
Probably Knox, at Dieppe in 1557 and early in 1558, did not know about the promising Band made in Scotland.
