Grace and peace! Did the Magisterial Reformers (Calvin, Luther, Bucer, ...) know of 1 Clement? Are there any quotiations or references of this Church Father in their writings? I suspect that they knew of Clement from Eusebius’ Historia Ecclesiastica or from Jerome’s De Viris Illustribus, but I don’t have any evidence that they read his letter. He would have been a great witness for them in their polemics with the Church of Rome.
