I too find some of these changes hard to believe, let me clarify why some are being "looked into".
JWs will in time, be allowed by conscience to wear tattoos or piercings, as long as they do not reflect "extremes" in the world or identify them with the LGBTQ community.
Smoking tobacco and marijuana as well as taking of drugs will still be strongly discouraged, however they will no longer be considered disfellowshipping offences and in most cases reproval will be the goal of judicial committees in these areas.
Again, this is due to the Governing Body's gradual changing of stance on what really is a decision by conscience and what really merits a disfellowshipping offence. Reportedly, many disfellowshippings take place because elders lack real discernment concerning whether a person is truly repentant or not. The GB are in panic mode, because this approach has created more "apostates" for them and they're now trying to crack down on the rise of apostasy, which is more common than sexual immorality within the org now. Speaking of which, the next point I certainly questioned:
Also, the Governing Body will issue a statement that different forms of sex within marriage (such as oral and anal) are now permissable, as long as a married couple does not openly talk about sex otherwise they will be counselled by the elders.
Additionally, private consensual intimacy and sex between adults of the opposite sex will be a conscience matter, as long as vaginal sex and pregnancy is not involved and as long as the activities are not broadcast openly to other members of the congregation. If a married person is involved, they must receive permission from their spouse and then respect their mate's decision if they refuse to permit it, otherwise a judicial committee will be formed and repeated attempts will be made to help that one gain "repentance".
The word porneia is being reexamined. The Governing Body feels that the current stance on it has actually contributed to more apostasy, more negative press against Jehovah's Witnesses. So a somewhat permissive compromise may help them escape further legal action, especially with the fact they plan on using the words "consent", "consensual" and specifically "adults", avoiding legal action with CSA cases in the Org. In fact, they may even relax on porn watching and encourage couples to enjoy it privately , but without mentioning it to the rest of the congregation. This I think is a complete deviation from Christianity in general anyway, so their attempts to use this as part of an effort to become more like "First Century Christianity" is pointless.
Regarding blood transfusions, there will be stronger statements issued regarding refusing blood. However, the mention of blood fractions will be removed altogether, and in time the Enjoy Life Forever book will be revised to reflect this change. HLCs will also have revised documents removing all mention of blood fractions, that doesn't mean JWs can stop using transfusion based alternatives with fractions of blood. The purpose of the proposed change is to again fight back against the criticisms of apostates and to "hide the evidence", so to speak, that transfusions are a conscience matter. Flip flopping around the issue, they plan on covering their own tracks.
Regarding the Memorial change, this adjustment has been a long time coming, considering JWs already loosely teach that if a member of the Great Crowd cannot attend the observance of the Memorial due to sickness then that's ok because the celebration is only in place for the remnant. Hope that makes sense.
