Blood policy - Announce 'new light' that since blood transfusions do not involve the loss of a life or 'soul' then they are not scripturally prohibited, since all scriptural injunctions against blood involve the loss of a life. But is totally up to one's conscience and applicable to baptised, mature members of the congregation only (not babies and children). Announce that it is sin to shun or ostracise persons who in good conscience have a blood transfusion.
Child abuse policy - Announce that the 'two witness' rule no longer applies, and the elders will immediately report all allegations of child abuse to the secular authorities, whether or not state law requires them too (God's ways should be higher than mans), and no paedophile is to ever have any privilege in the congregation again, ever!
Shunning/disfellowshipping policy - announce that the pre-Knorr policy is to be reinstated, ie, that persons who simply disagree with some teaching or policy are not to be shunned. And all other shunning is for social interaction only, not absolutely and total shunning (ie, marking, not shunning). You can still say hello and be generally polite and spiritually encouraging but shouldn't eat or socialise with willfully immoral, unrepentant persons (mark them, but don't shun).
1914 - announce that it is a matter of personal choice whether one wishes to believe it or not, and that it's no longer a mandatory requirement of belief to remain in good standing or to preach it.
Door to door work - announce that it is no longer required or expected of everyone, but only those who voluntarily wish to devote themselves to Jehovah's service in this special way (as is the case with any other congregational privilege).
