Pretty interesting catalogue of resources. It took me a long time to find out which movement he was coming from. His book on the Restoration Movement (i.e. Campbellism) makes it clear he is in the Campbell/Stone camp.
While I admire the ideal of the Restoration movement, they too make some of the same mistakes in projecting 2nd. century thought into the NT. They may be on my side rearding communion, but with Baptism, they are clearly on the Catholic side, and then there's the ridiculous instruments philosophy, which has been used a lot lately on the Music forum by the traditional-only side (ven though they use instruments).

Jesse Lyman Hurlbut The Story of the Christian Church p.41
We would like to read of the later work of such helpers of St. Paul as Timothy, Apollos, and Titus., but all these...drop out of record at his death. For 50 years after St. Paul's life a curtain hangs over the church through which we strive vainly to look; and when at last it arises, about AD 120, with the writings of the earliest church fathers [Justin], we find a church in many aspects different from that in the days of Peter and Paul
William Fitzgerald, Lectures on Ecclesiastical History:
...over this period of transition, which immediately succeeds upon the era properly called apostolic, great obscurity hangs...
Philip Schaff, History of the Christian Church
The remaining 30 years of the first century are involved in mysterious darkness, illuminated only by the writings of John. This is a period of church history about which we know least and would like to know most.
William J. McGothlin, The Course Of Christian History
But Christianity itself had been in [the] process of transformation as it progressed and at the close of the period was in many respects quite different from the apostolic Christianity -
Samuel G. Green, A Handbook of Christian History:
The 30 years which followed the close of the New Testament Canon and the destruction of Jerusalem are in truth, the most obscure in the history of the Church. When we emerge in the second century, we are, to a great extent, in a changed world
