A feed your members follow, where people answer « I am praying for you » rather than a thumbs up. Every post picks its audience - members only, or the church's public page. With no algorithm deciding who sees what.

The roof fund concerns the members. Saturday's food parcels concern the neighbourhood. Two audiences, and it is a setting on the post - not two tools, not two entries.
An announcement in a chat group disappears under the next day's messages. Here it stays, it can be found again, and you know what it reached.
A product page that only says good things is a page nobody believes. Here is the exact limit.
Write it once, choose its audience, and find it again in three months.
