Here is the same editor, but on your church's letterhead, with your templates, your signature and your stamp. And one thing Word will never do: a QR that proves the document is genuine.

The tools shown are the editor's own, in their real order. The church, the person and the dates are examples.
A hand-signed certificate proves nothing. A QR code at the foot of the page does.
A certificate gets typed in Word, on a template somebody made three years ago, with a logo pasted crooked. You retype the name, check the address, hunt for the wording. And the subscription is paid every month, for that.
A church document sometimes ends up with an employer, a school, a bank or an immigration office. And the person on the other side has no way of knowing whether it is real: a logo can be copied, a signature scanned, a stamp imitated. A word processor cannot solve that, because it is precisely the tool used to fabricate it.
Once the document is ready the second chore begins: export it, find the person's address, write the email, attach the file. And six months later nobody knows whether it was sent, or how many times.
We do not claim to replace a whole office suite. For a church's documents, however, the question does not arise.
Set your letterhead once, pick a template, name the member. The document leaves with its QR, and anyone can check that it really came from you.
