The answer is: Charge it to the writer

v18-19 - maybe the slave had stolen from the master? Paul writes this bit with his own hand to be legally binding.

In Philemon, we witness a remarkable and poignant moment about forgiveness and reconciliation set against the harsh realities of slavery. When Paul suggests that Philemon charge any debts from Onesimus, it not only reflects on early Christian values but also highlights the deep bonds that are formed in faith. To literally "charge it" means to take a new financial perspective on relationships marked by unbalanced power dynamics. This act questions the very nature of ownership and identity.

Interestingly, this letter provides one of the earliest commentaries on how love and forgiveness should transcend injustice, serving as a unique glimpse into the social and moral attitudes of the time. Paul does not condone slavery but instead recasts relationships in terms of brotherhood; Paul calls Onesimus "my own heart," emphasizing the spiritual equality of all believers, hence fostering a community filled with mutual respect.

Trivia buffs might find it fascinating that a number of ancient manuscripts reference Onesimus, hinting that he might have gone on to become a bishop in the early Christian church, showcasing how transformation through faith is genuinely at the heart of this story. Paul's poignant request rides the wave of early Christian egalitarian ideals, which deviated from the norm. It aligns with the overarching biblical themes that advocate for compassion and justice, subtly nudging us to reconsider our relationship with societal structures—even those that seem firmly established.
