Is the Xt Canonical?

The story of a woman accused of sins before jesus is said to be from the second century. The themes of judgment in chapters seven and eight seem to fit it thematically. If this is an authentic gospel witness that has, by god's providence, come down to us treating it as quasi canonical may not be inappropriate. But we should beware of resting any doctrine too heavily upon this passage by itself. We should bracket it from the material that surrounds it, too,. And also be alert to the ways in which, if such practing is not handled carefully, it interrupts the flow of john's own account.
