1 Corinthians 3:1-3

Williams(i) 1 So I myself, brothers, could not deal with you as spiritual persons, but as creatures of human clay, as merely baby Christians. 2 I fed you with milk, not solid food, for you could not take it. Why, you cannot take it even now, 3 for you are still unspiritual. For when there are still jealousy and wrangling among you, are you not still unspiritual and living by a human standard?
