Again in the year 1648, when Cromwel came to Edinburgh, the commission of the kirk sent Mr. Blair and Messrs. David Dickson and James Guthrie to deal with him, for an uniformity in England. When they came, he entertained them with smooth speeches and solemn appeals to God as to the sincerity of his intentions. Mr. Blair being best acquaint with him, spoke for all the rest; and among other things, begged an answer to these three questions: (1.) What was his opinion of monarchical government? He answered, He was for monarchical government, &c. (2.) What was his opinion anent toleration? He answered confidently, That he was altogether against toleration. (3.) What was his opinion concerning the government of the church? O now, said Cromwel, Mr. Blair, you article me too severely; you must pardon me, that I give you not a present answer to this, &c. This he shifted, because he had before, in conversation with Mr. Blair, confessed he was for independency. When they came out, Mr. Dickson said, I am glad to hear this man speak no worse; whereunto Mr. Blair replied, If you knew him as well as I, you would not believe one word he says, for he is an egregious dissembler and a great liar. When the differences fell out betwixt the protestors and resolutioners, Mr. Blair was at London, and afterward for the most part remained neuter in that affair; for which he was subjected to some hardships; yet he never omitted any proper place or occasion for the uniting and cementing these differences, none now in Scotland being more earnest in this than he and the learned and pious Mr. James Durham minister at Glasgow. These two, meeting at St. Andrews, had the influence to draw a meeting of the two sides to Edinburgh, where harmony was like to prevail; but the Lord's anger, being still drawn out for the prevailing sins of that time, all promising beginnings were blasted, and all hopes of agreement did vanish. Thus affairs continued until the year 1660, that the kingdom, being quite sick of distractions, restored again Charles II.; the woeful consequences are otherwise too well known; And, on this last occasion, Mr. Blair again began to bestir himself to procure union betwixt the two foresaid parties, and for that end obtained a meeting; but his endeavours were frustrated, and no reconciliation could be made, till both sides were cast into the furnace of a sore and long persecution. For in Sept. 1661, Mr. Sharp came to St. Andrews, and the presbytery, having had assurance of his deceitful carriage at court, and of the probability of his being made arch-bishop of St. Andrews, sent Mr. Blair, and another, to him, to discharge their duty, which they did so faithfully, that Sharp was never at ease till Mr. Blair was rooted out.
