Doing the Social Media for Church

I've been asked to assist with social media posting for my church, to take some of the burden off the PCC and reach people who may not know we exist. So far, this involves a Facebook page, although may branch out into other platforms. We're a traditional Anglo-Catholic church in Yorkshire.

Any tips? Pitfalls to avoid? (I get the feel we're going for dignified and respectful, so I'll keep my spicy memes and theological hot takes to myself)
