 It should also be remembered, where matters of detailed wording are concerned, that there is some uncertainty in the Gospel texts themselves, as textual criticism of the gospels is still an active field, which cannot even decide, for example, on Mark's original ending.Such issues often intersect with the synoptic problem; for example, Streeter famously dismissed many of the "minor agreements" so troublesome for the two-source theory by appealing to textual corruption driven typically by harmonization.Mark's style of Greek is unique among the Gospels.
