Please find guidelines for your use of social media here. These are straightforward and are taken from the national church website. They are not meant to discourage you from using social media but rather to remind you to be sensitive in how you use it. Too often things that a person has thought restricted to a small number of friends ends up in the public domain. Similarly I often get notice of things that have been posted supposedly privately. It is safest to assume that anything you post (on any of the platforms) is public and act accordingly.
In all that we say and do we need to be aware of our responsibilities to Christ and to his Church.
Be safe and be kind,
