I have written to you, my children, because you know the Father (patera | πατέρα | acc sg masc). I have written to you, fathers (pateres | πατέρες | voc pl masc), because you know him who is from the beginning. I have written to you, young men, because you are strong, and the word of God abides in you, and you have overcome the evil one.
