Archibald Alexander Hodge - The Day Changed and the Sabbath Preserved (1877) . . . In this short tract, published the year he arrived at Princeton Seminary to assist his father Charles Hodge in teaching systematic theology, A. A. Hodge sets forth a clear biblical, theological, and historical case that the Lord's Day is the Christian Sabbath day, in spite of the change from the seventh day of the week to the first day.
