This letter is addressed to a particular recipient, a man named Gaius. This letter to serves to encourage Gaius in what he is doing and to commend him in his role is supporting the wider church.
Whereas 2 John warns against letting false teachers stay in the believers’ homes, this letter praises Gaius for his hospitality towards genuine teachers. Gaius is contrasted against a man called Diotrephes. Diotrephes seems controlling, overbearing and power-hungry. He is not welcoming to travelling teachers.
I suppose the lesson in this letter, who would you rather be: Gaius or Diotrephes. Gaius is remembered for putting others’ needs before his, for opening his home up and accepting fellow believers. He often, it seems, opens his home to those who he has never met before. I’m sure that wasn’t an easy decision, as it can open yourself to being vulnerable. (I imagine it could have been even riskier in those times.) Diotrephes, as verse nine tells us, “loves to be first”. Therefore, he seems to spread rumours about other authority figures and refuse to welcome them.
Of course, we answer, I want to be Gaius! But do our lives actually reflect that? Are we sometimes eager to cling onto our power or reputation? Are we intimidated of those that might be seen as better than us? Do we belittle others in order to bolster our ego and reputation? Or, are we open handed and hospitable? Do we welcome travellers and strangers into our homes? Do we put the needs, reputations and honour of others before ourselves? I wonder what the church would look like if everybody followed this better example.
