The Public or Thursday Lecture, dating from the ordination of the Rev. John Cotton, in 1633, continued with occasional interruptions till the siege of 1775, later revived and existing, it is claimed, still, or until recently (see Dr. Samuel A. Eliot's Preface to _Pioneers of Religious Liberty in America_, Boston, 1903), was famous among the social and religious institutions of colonial Boston. At one time the General Court regularly adjourned for it; that the Governor should keep Christmas and neglect it, was regarded by old Judge Sewall as a matter of grave reproach. The preachers were selected from the most eminent divines, not only of Boston, but throughout the colony. It is recorded, for instance, of Solomon Stoddard, Edwards's grandfather and predecessor in the Northampton pastorate, that he annually attended the Harvard Commencement and the day after preached the Public Lecture. It was a great honor, therefore, for Edwards, a young man of twenty-seven, to be invited to preach on this foundation. He himself seems to have fully appreciated both the honor and the opportunity. The original manuscript shows the most careful preparation. In the statement of the Doctrine, for example, there are several erasures and corrections before the right formula is hit upon. The printed sermon shows still more elaboration. Edwards chose as his subject one aspect of a theme which was central and controlling in his thought--God's sovereignty. His mind had dwelt on this subject in all its bearings from childhood. He had especially meditated upon it as it related to the doctrine of decrees, a doctrine which he found at first revolting, but in the end "exceedingly pleasant, bright, and sweet." No one since Augustine has emphasized as he has done the absolute sovereignty of God and the corresponding dependence of man. This conception of God's arbitrary will--arbitrary, not as irrational or unrelated to the divine justice and benevolence, but as being "without restraint, or constraint, or obligation"--was not only the backbone of his system, but its heart, the principle which animates and pulses through the whole of it. It is the ultimate basis alike of his philosophy and of his religious faith. In this his first publication as in the great theological treatises which were his last, he is everywhere the prophet-like champion of this supreme idea in opposition to all those schemes of divinity, generally denominated Arminian, which implied in his view a degree of independence in man inconsistent with the absolute sovereignty he regarded as the distinguishing glory of God.
