From the pen of Barth...

This is what Barth says concerning the Scriptures:

The prophets and apostles, even in their office, even in their function as witnesses, even in the act of writing down their witness, were, as we are, capable and actually guilty of error in their spoken and written word. (Dogmatics, I, 528-9)

If God was not ashamed of the fallibility of all the human words of the Bible, of their historical and scientific inaccuracies, their theolgical contradictions, the uncertainty of their tradition, and, above all, their Judaism, but adopted and made use of these expressions in all their fallibility, we do not need to be ashamed when He wills to renew it to us in all its fallibility as witness; and it is mere self-will and disobedience to try and find some infallible elements in the Bible (Dogmatics, I, 531).

The men whom we hear as witnesses speak as fallible, erring men like ourselves. . . . We can read and try to assess their word as a purely human word. It can be subjected to all kinds of immanent criticism, not only in respect of its philosophical, historical, and ethical content, but even of its religious and theological. . . . Each in his own way and degree, they shared the culture of their age and environment. . . . The vulnerability of the Bible, i.i., its capacity for error, also extends to its religious or theological content. There are obvious overlappings and contradictions. . . . Therefore, whether we like it or not, they did not speak a special language of revelation radically different from that of their time. . . . It seems to be weakened, and therefore robbed of its character as witness ot revelation, by the fact that it has so many "parallels" (Dogmatics, I, 507-9). Emphasis Added
