It was the last time that the Rabbi ever spoke in public, and it is now agreed that the deliverance was a fit memorial of the most learned scholar that has been ever known in those parts. He began by showing that Christian doctrine has taken various shapes, some more and some less in accordance with the deposit of truth given by Christ and the holy Apostles, and especially that the doctrine of Grace had been differently conceived by two eminent theologians, Calvin and Arminius, and his exposition was so lucid that the clerk gave it as his opinion afterwards that the two systems were understood by certain members of the court for the first time that day. Afterwards the Rabbi vindicated and glorified Calvinism from the Scriptures of the Old and New Testament, from the Fathers, from the Reformation Divines, from the later creeds, till the brain of the Presbytery reeled through the wealth of allusion and quotation, all in the tongues of the learned. Then he dealt with the theology of Mr. Erskine of Linlathen, and showed how it was undermining the very foundations of Calvinism; yet the Rabbi spake so tenderly of our Scottish Maurice that the Presbytery knew not whether it ought to condemn Erskine as a heretic or love him as a saint. Having thus brought the court face to face with the issues involved, the Rabbi gave a sketch of a certain sermon he had heard while assisting "a learned and much-beloved brother at the Sacrament," and Carmichael was amazed at the transfiguration of this very youthful performance, which now figured as a profound and edifying discourse, for whose excellent qualities the speaker had not adequate words. This fine discourse was, however, to a certain degree marred, the Rabbi suggested, by an unfortunate, although no doubt temporary, leaning to the teaching of Mr. Erskine, whose beautiful piety had exercised its just fascination upon his spiritually-minded brother. Finally the Rabbi left the matter in the hands of the Presbytery, declaring that he had cleared his conscience, and that the minister in question was one--here he was painfully overcome--dear to him as a son, and one to whose many labours and singular graces he could bear full testimony, the Rev. John Carmichael, of Drumtochty. The Presbytery was slow and pedantic, but was not insensible to a spiritual situation, and there was a murmur of sympathy when the Rabbi sat down--much exhausted, and never having allowed himself to look once at Carmichael.
