5 Under these circumstances it would have been well for many of us to have travelled to your reverences, and to have individually reported each his own position. You may now take as a proof of the sore straits in which we are placed the fact that we are not even free to travel abroad. For if any one leaves his Church, even for a very brief space, he will leave his people at the mercy of those who are plotting their ruin. By God's mercy instead of many we have sent one, our very reverend and beloved brother the presbyter Dorotheus. He is fully able to supply by his personal report whatever has been omitted in our letter, for he has carefully followed all that has occurred, and is jealous of the right faith. Receive him in peace, and speedily send him back to us, bringing us good news of your readiness to succour the brotherhood.
