A friend of mine who divorced for reasons other than porneia and subsequently started dating was disfellowshipped "not on grounds of sexual misconduct, but because of your wilful violation of [Bible] principles ... The principles of God's law do not allow for partial disregard of his requirements, as long as we do not go all the way in disobedience. The fruit of the forbidden tree in Eden was not only not to be eaten, but the act of touching it, in order to decide whether to put it into the mouth, was in itself punishable by death. (Gen. 3:3.) Eve's transgression was complete the moment she put her hand to the tree."
That was "brazen conduct" nearly 40 years ago.
