The controversy in Germany has turned chiefly on this.

The critics have set themselves to show that the variations in Marcion's Gospel either could or could not be explained as omissions dictated by the exigencies of his dogmatic system.

This was a task which suited well the subtlety and inventiveness of the German mind, and it has been handled with all the usual minuteness and elaboration.

The result has been that not only have Volkmar and Hilgenfeld proved their point to their own satisfaction, but they also convinced Ritschl and partially Baur; and generally we may say that in Germany it seems to be agreed at the present time that the hypothesis of a mutilated Luke suits the dogmatic argument better than that of later Judaising interpolations.
I have no wish to disparage the results of these labours, which are carried out with the splendid thoroughness that one so much admires.

Looking at the subject as impartially as I can, I am inclined to think that the case is made out in the main.
