This dissertation argues that the letter to Philemon constructs a koinonia-space, a space of radical kinship that challenges both the noxious nucleus of Roman slavery and systemic dehumanization in the Democratic Republic of Congo. Considering the content of Paul’s prayer in verses 4-6 and his challenging request in verse 16 as the hermeneutical keys to the whole letter, the message of the letter to Philemon is a summons to an ethic of koinonia among the followers of Christ.
