Well, let me explain my question a bit. We are talking here about a very important message, that can change the lives and destinies of billions of people. You are only going to speak once. So, what method of communication would you chose?
Would you chose to send the message yourself, directly, or would you rely on people who will require faith to communicate with you and then rely on faith of others to accept your message?
I'm sorry, but still not sure I get it. If you gave the message to someone to pass on to someone else, that's not necessarily a matter of faith but of
competence. I mean, I guess it is a kind of 'faith' that the person won't mess it up along the way, but it is better to know you are trusting your message to competent people (if that's how you choose to disseminate it) then to just hope it gets to wherever you want it go.
I suppose I would put it out on the internet, via social media, probably directed towards some major corporation, since that's how most news spreads around the world these days. I'd probably write it myself and then have someone else look it over to make sure it says what I'm intending it to say, as I'm not a good judge of my own ability.
If it is meant to be an analog to the spread of the Christian faith or the composition and transmission of the scriptures or whatever (just a guess on my part), I would say that it is very malformed, as globally societies have changed a lot in the last 2,000-odd years in terms of their access to technology and ability to spread news. Today even the most closed off societies (e.g., Saudi Arabia, North Korea, Eritrea, Iran, etc.) have some way to access the outside world, even if it must be done somewhat surreptitiously, as via an illegal satellite hookup, bootleg DVDs smuggled in from the nearest free(r) foreign country's markets, etc. There's always a way, and it very rarely comes down to people on foot, or camel/horseback, or by sea. That still does sometimes happen, but it's rare. I met a monk of my own church who did that, under the direction of his bishop who had received the blessing of our then-Pope (HH Pope Shenouda III). So it's a thing that might be found in some particular traditions, but even then, most Coptic people can at least
access the internet (most the church globally is poor farmers in Egypt, but I mean the country itself has internet, satellite TV, and so on).
So...I would use the internet, but I'm not sure what this means or proves relative to what you're asking.
