As I understand it, when the WT temporarily softened their stance on DF'ing back in the 70's, the article came from Ray. Here's the relevant part:
WT 8-1-74:
9 What, then, if a congregation elder were to meet up with a person who had been disfellowshiped, perhaps in the elder’s daily routine, on the street, in his secular work or similar activity? Would the elder be acting out of harmony with the congregation’s disfellowshiping action if he spoke to this one, urging him or her to ‘turn around’ and seek reconciliation again with his heavenly Father? Circumstances would govern. Of course, if the disfellowshiped one were following a course like those false teachers and propagandists described at 2 John 7-11, deliberately trying to influence others into false beliefs or immoral practices, the elder would want nothing to do with such a one. But not all who slip into a sinful way become ‘deceivers and antichrists.’ So, if that one is not of that class, would not Jehovah God’s own example allow for the elder to speak words exhorting the disfellowshiped one to seek to regain a good standing with God? Rather than being out of harmony with the disfellowshiping, by his words of exhortation the elder actually would show his support of such disfellowshiping action as having been right and needed.
10 We may note, too, that at 1 Corinthians 5:11 the apostle warns against mixing in company with one who “is” a fornicator or practicer of some other kind of serious wrongdoing. What, however, of the one who has been disfellowshiped for being that kind of person but who thereafter, either at an early point or at a later point in time, gives consistent evidence of discontinuing such wrong practice, stopping it? Can it be said that he or she still “is” a fornicator or whatever type of wrongdoer such a one was that caused him or her to be as “leaven” toward the congregation?
11 For example, a young person disfellowshiped for fornication may thereafter marry, raise a family and live a respectable life. Or one who was disfellowshiped for drunkenness may abandon such practice and, if drinking at all, may do so in moderation only. By such changes these individuals may now regain the respect of the community. Such ones may not yet have come and formally sought reinstatement by the congregation. Is there, however, not an evident difference between these and others who continue right on in the wrongdoing that brought their disfellowshiping? Those giving up the wrong practice may still manifest some appreciation for Christian truth, perhaps even defending the true Christian congregation when someone speaks evil against it. Should not such circumstances be given due weight and have an effect on our attitude as a congregation toward such ones?
