In speaking of his own preaching in 1556, Knox tells that, at that time, most of the gentlemen of the Mearns “refuissed all societie with idolatrie, and _band thame selfis_, to the uttermost of thare poweris, to manteane the trew preaching of the Evangell of Jesus Christ, as God should offer unto thame preachearis and oportunitie.” Dr M‘Crie understood this to mean that these gentlemen “entered into a solemn and mutual bond, in which they renounced the Popish communion, and engaged to maintain and promote the pure preaching of the Gospel, as Providence should favour them with opportunities.” In David Laing’s opinion, Knox’s words do not necessarily imply that the mutual agreement or resolution referred to actually assumed the form of a written “band” or covenant. If it did, Knox has not embodied it in his “History,” nor is any copy known to exist. [Sidenote: Band of 1557] But as to the reality, the nature, and the precise date of the band of 1557, there is no room for dubiety. Knox was on the Continent when it was entered into; but he relates the circumstances which called it forth, explains the object it was meant to serve, and gives a copy of the document itself, as well as the names of the principal men who signed it. The leaders of the Reforming party resolved to persist in their purpose, to commit themselves and their all into God’s hands, rather than allow idolatry manifestly to reign, rather than suffer the subjects of the realm to be defrauded as they had been of the preaching of Christ’s Evangel. “And that everie ane should be the more assured of other, a commoun band was maid, and by some subscrived.” Calderwood derived his copy of the document, and his account of the circumstances which called it forth, from Knox. Fully forty years ago an original copy of the band was found, and is now in the National Museum of Antiquities, Edinburgh. It only bears five signatures, those of Argyll, Glencairn, Morton, Lorne, and John Erskine. The day of the month is left blank; but the one which Knox followed is dated “the thrid day of December.” Knox also says that it was subscribed by many others. The explanation probably is that (as in 1638) a number of original copies were made, and signed by the leaders before being sent out for additional names.
