First - if you hope to become an elder, in the UK you will also become a charitable trustee. You will not be given any training for this part of your role. Your details will be sent to the Charity Commission. As an elder and charitable trustee, you might at some time be unable to agree with the BoE on a matter. Nevertheless, the WTBTS expects you to acquiesce with the majority. Yet you will be legally held responsible for your individual decision as a trustee.

What if you can't become a trustee*, would that also prevent you from ever becoming an elder?
