3 surviving letters between Caesaria the patrician and Severus of Antioch, spanning 526-534 AD.
Severus denies a forged treatise, then warns Caesaria against false asceticism that despises marriage, food, or the body.
Severus urges Caesaria not to bind herself to one celebrant's oblation and to seek healing through confession and faith.
Severus distinguishes ordinary kindness from liturgical communion with people he regards as heretics.
