This noun denotes arrival or, paradoxically, departure—the act of coming to or leaving a place. Paul uses it in Acts 20:29 when he warns the Ephesian elders that 'after my departure' (μετὰ τὴν ἄφιξίν μου) savage wolves will enter the flock. The term can mean either 'arrival' or 'departure' depending on context; here it clearly means Paul's leaving. Classical usage favors 'arrival,' but later Greek extends it to departure. Paul's warning is sobering: his protective presence will soon be removed, and false teachers will infiltrate. The ἄφιξις marks a transition from apostolic oversight to congregational vigilance.
