Archibald Alexander Hodge first published his book, A Commentary on the Confession of Faith: With Questions for Theological Students and Bible Classes, in 1869 (Presbyterian Board of Publication). His Outlines of Theology preceded it by nearly a decade, having been published in 1860. In it he writes of the covenant of works, “It was also essentially a gracious covenant, because although every creature is, as such, bound to serve the Creator to the full extent of his powers, the Creator cannot be bound as a mere matter of justice to grace the creature fellowship with himself.” In his posthumously published Evangelical Theology: A Course of Popular Lectures (1890), Hodge similarly states, “God offered to man in this gracious Covenant of Works the opportunity of accepting his grace and receiving his covenant gift of a confirmed holy character” (167).

So A. A. Hodge sounds just like John Calvin.
