By focusing on the work, I am referring to discerning the true nature of Jesus’ teaching, how we can align with it, and what we can do and think to be in harmony with it.
As for the corrections, I count virtually everything and anything that dilutes, weakens, adulterates, laces, misinterprets, denatures, taints, or corrupts the work and its essence.
Detecting the corrections and distinguishing it from the work is not always easy, but it is always worth the effort.
