I write to you, fathers, because you know him who is from the beginning. I write to you, young men, because you have overcome the evil one. I write to you, little children, because you know the Father.
Some have supposed, also, that the expression “I have written,” refers to some former epistle which is now lost, or to the Gospel by the same author, which had been sent to them (Hug.), and that he means here to remind them that he had written to them on some former occasion, inculcating the same sentiments which he now expressed. But there is no evidence of this, and this supposition is not necessary in order to a correct understanding of the passage. In the former expression, “I write,” the state of mind would be that of one who fixed his attention on what he was “then” doing, and the particular reason “why” he did it - and the apostle states these reasons in 1 John 2:12-13. Yet it would not be unnatural for him immediately to throw his mind into the past, and to state the reasons why he had resolved to write to them at all, and then to look at what he had purposed to say as already done, and to state the reasons why that was done.
