The CBGM: Only Increasing Uncertainty
“In all, there were in the Catholic Letters thirty-two uses of brackets compared to forty-three uses of the diamond and in Acts seventy-eight cases of brackets compared to 155 diamonds. This means that there has been an increase in both the number of places marked as uncertain and an increase in the level of uncertainty being marked. Overall, then, this reflects a slightly greater uncertainty about the earliest text on the part of the editors.”
