Paul appeals to Philemon to acknowledge in this instance the transformation that occurs in relationships because of the reality of what it means to be in Christ: master and slave are transformed into brothers.
15Perhaps this is the reason he was separated from you for a while, so that you might have him back for ever, 16no longer as a slave but as more than a slave, a beloved brotherespecially to me but how much more to you, both in the flesh and in the Lord.
