Campbell published his four-part series on the biblical Tabernacle in the Millennial Harbinger 1861, the year he turned seventy-three. By that point in his life, Campbell was not nearly as sharp or focused as he had been when he was younger.
Perhaps his disappointments and heartaches, not to mention the distress of the unfolding war, were taking their toll. Whatever the causes, the articles in the series are rambling and disjointed. Lauding the glories of Creation, at other times chiding skeptics, Campbell sometimes writes several paragraphs that never mention his subject. At other points, he includes long quotes from other sources. In the second installment, Campbell quotes almost all of Psalm 72, again, without an obvious need or a necessary connection to his subject.
Nevertheless, the series contains a few particulars about Campbell's understanding of the Tabernacle. For example, regarding the three sections of the Tabernacle and its precincts, Campbell wrote:
"The outer court, at the proper angle of vision, represents the world, dead in trespasses and in sins; the holy place, the church; and the holiest of all, heaven itself." (No. 2, p. 151)
On the great significance of the Tabernacle and the rituals that took place there, Campbell said:
"Were we to enter into all the details of the Tabernacle and its worship, we should need a small volume rather than a short essay. We generally, in our college duties, deliver annually a series of lectures on this institution, and our opinion is, that the Tabernacle and its worship, thoroughly developed, is the best system of theology, properly so called, known to us in all the theologies of our country." (No. 2, p. 156)
