What did 19th century Presbyterians think about the canon of Scripture? Here are two sources.

The topic of the canon of Scripture is always interesting and difficult for Christians. We must remember, however, that we are not the first to ask questions about the canon. In the 19th century, Archibald Alexander and Francis Smith Sampson each wrote on the topic of canon. Alexander wrote a book entitled The Canon of the Old and New Testaments Ascertained, or The Bible Complete without the Apocrypha and Unwritten Traditions (1851), and Sampson gave two lectures on "The Authority of the Sacred Canon and the Integrity of the Sacred Text."  Undoubtedly, the way we approach this question has changed since the mid-1800s. But there is bound to be wisdom and insight we can glean from these fathers in the faith.
