What you can do
See which churches are on the roster. Share an event or a cooperative purchase when they opt in. Invite a church with a code they enter themselves. We do not scrape a denomination list and email pastors who never asked.
Spiritual and organizational
The point is still people: a smaller church that needs a pulpit supply, a shared outreach, a secretary who should not retype the same calendar. For the local desk see church software. For a public site see church website.
