Ampliatus (Ἀμπλίας) was a member of the Roman church whom Paul greets in Romans 16:8 as 'my dear friend in the Lord.' The name was common among Roman slaves and freedmen.
The greeting of Ampliatus in Romans 16 is a window into the early church's radical social diversity. Ampliatus was a common slave name — yet Paul calls him 'my dear friend in the Lord' (agapeton mou en kyrio). The gospel had created genuine friendship across the deepest social divides of the ancient world. Archaeological evidence from the Catacomb of Domitilla in Rome shows an early Christian burial inscription for one 'Ampliatus' — possibly this very person — buried with honor near members of the imperial household, illustrating how in Christ 'there is neither slave nor free' (Galatians 3:28). The beloved slave and the noble are brothers in the Lord.
