Knox returned to Scotland for a brief visit of about ten months (Sept. 1555-July 1556). He exhorted those who visited him in his lodgings in Edinburgh, and made preaching tours, dispensing the Lord's Supper according to the Reformed rite on several occasions. He visited Dun, Calder House, Barr, Ayr, Ochiltree, and several other places, and was welcomed in the houses of many of the nobility. He left for Geneva in July, having found time to marry his first wife, Marjory Bowes,--_uxor suavissima_, and "a wife whose like is not to be found everywhere,"[294] Calvin calls her,--and having put some additional force into the growing Protestantism of his native land. He tells us that most part of the gentlemen of the Mearns "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 preacheris and opportunitie"--whether by word of mouth or in writing, is not certain.[295] In 1557 (Dec. 3rd) the Protestants of Scotland laid the foundations of a definite organisation. It took a form familiar enough in the civil history of the country, where the turbulent character of the Scottish barons and the weakness of the central authority led to constant confederations to carry out with safety enterprises sometimes legal and sometimes outside the law. The confederates promised to assist each other in the work proposed, and to defend each other from the consequences following. Such agreements were often drafted in legal fashion by public notaries, and made binding by all forms of legal security known. The _Lords of the Congregation_, as they came to be called, followed a prevailing custom when they promised-- "Befoir the Majestie of God and His congregatioun, that we (be His grace) shall with all diligence continually apply our hole power, substance, and our verray lyves, to manteane, sett fordward, and establish the most blessed word of God and His Congregatioun; and shall laubour at our possibilitie to have faythfull Ministeris purely and trewlie to minister Christis Evangell and Sacramentes to His people."[296] This "Band subscrived by the Lords" was the first (if the promise made by the gentlemen of the Mearns be excepted) of the many Covenants famous in the history of the Church of Scotland Reformed.[297] It was an old Scottish usage now impregnated with a new spiritual meaning, and become a public promise to God, after Old Testament fashion, to be faithful to His word and guidance. This important act had immediate consequences. The confederated Lords sent letters to Knox, then at Geneva, and to Calvin, urging the return of the Scottish Reformer to his native land. They also passed two notable resolutions:
