Baur and Ritschl professed themselves convinced by the arguments brought forward, and retracted or greatly modified their views.

So far as I am aware, Schwegler is the only writer whose opinion still stands as it was at first expressed; but for some years before his death, which occurred in 1857, he had left the theological field.
Without at all prejudging the question on this score, it is difficult not to feel a certain presumption in favour of a conclusion which has been reached after such elaborate argument, especially where, as here, there could be no suspicion of a merely apologetic tendency on either side.

Are we, then, to think that our English critic has shown cause for reopening the discussion?
There is room to doubt whether he would quite maintain as much as this himself.

He has gone over the old ground, and reproduced the old arguments; but these arguments already lay before Hilgenfeld and Volkmar in their elaborate researches, and simply as a matter of scale the chapter in 'Supernatural Religion' can hardly profess to compete with these.
Supposing, for the moment, that the author has proved the points that he sets himself to prove, to what will this amount?
He will have shown (a) that the patristic statement that Marcion mutilated St.Luke is not to be accepted at once without further question; (b) that we cannot depend with perfect accuracy upon the details of his Gospel, as reconstructed from the statements of Tertullian and Epiphanius; (c) that it is difficult to explain the whole of Marcion's alleged omissions, on purely, dogmatic grounds--assuming the consistency of his method.
With the exception of the first, I do not think these points are proved to any important extent; but, even if they were, it would still, I believe, be possible to show that Marcion's Gospel was based upon our third Synoptic by arguments which hardly cross or touch them at all.
But, before we proceed further, it is well that we should have some idea as to the contents of the Marcionitic Gospel.

And here we are brought into collision with the second of the propositions just enunciated.
