The modern practice of disfellowshipping, and the shunning that accompanies it, started with the March 1, 1952 Watchtower magazine. Here are the articles.
(Watchtower Magazine, March 1, 1952) Keeping the Organization Clean, p 131
Propriety of Disfellowshiping, p137
Sin Making Reinstatement Impossible, p145
Just 5 years earlier, in the January 8, 1947 Awake Magazine, p27 & 28, the Organization strongly condemned the practice of 'excommunication,' which is acknowledged by Watchtower to be the same as disfellowshipping. That article said the following regarding (mainly) the Catholic Church's practice of excommunication (df'ing).
How many of the things listed below are now a part of Watchtower practice?
- You are looked upon with the "blackest contempt."
- You are cursed with the Devil and his demons.
- Abandoning the Church's faith, or joining an offshoot of it, are reasons for excommunication.
- It is a part of canon [organization] law which the Heirarchy presents as "God's law."
- the 1947 article says that excommunication is unscriptural because it is not based on the teachings of Christ and the apostles.
- Excommunication should not be a "punishment" nor a "medical remedy" for sins committed.
- It is "foreign to Bible teachings."
- Excommunication has "pagan influence" and "superstitious" beliefs behind it.
- The practice was adopted by Catholics only after 325 A.D.
- It accompanies the growing "pretentions" of a heirarchy.
- It is used as a "weapon."
- It is used to gain "ecclesiastical power" through "secular tyrrany."
- Excommunicated people are viewer as "executed" and opposers are "impaled."
- It was used to control and punish those who "opposed the dictates" of the heirarchy.
- Excommunicated people lead a "doomed existence."
- Excommunicated people are "plotted against." Attacking their lives is "accounted virtuous."
As a side point here is a remark from the article Keeping the Organization Clean, saying that Miriam (Moses' sister) was disfellowshipped for 7 days for being 'high-minded, proud and foolish' by being stricken with leprosy. Have you ever heard of anybody being df'd for just 7 days? Watchtower must have been reaching for any Biblical example it could find to support it's new teaching of disfellowshipping.
