Acknowledgment of their kindness
You have done well in receiving Philo and Rheus Agathopus as servants of Christ our God, who have followed me for the sake of God, and who give thanks to the Lord in your behalf, because you have in every way refreshed them. None of these things shall be lost to you. May my spirit be for you, and my bonds, which you have not despised or been ashamed of; nor shall Jesus Christ, our perfect hope, be ashamed of you.
