Appendix I. Cyprian’s idea of the Church and the actual circumstances.
Addendum I. The great confederation of Churches which Cyprian presupposes and which he terms the Church was in truth not complete, for it cannot be proved that it extended to any regions beyond the confines of the Roman Empire or that it even embraced all orthodox and episcopally organised communities within those bounds. But, further, the conditions of the confederation, which only began to be realised in the full sense in the days of Constantine, were never definitely formulated — before the fourth century at least. Accordingly, the idea of the one exclusive Church, embracing all Christians and founded on the bishops, was always a mere theory. But, in so far as it is not the idea, but its realisation to which Cyprian here attaches sole importance, his dogmatic conception appears to be refuted by actual circumstances.
