Paul dealt with milk necessary to try and wake them from looking outside themselves which children's still not able for meat, that teaching does anger them or scare them by secret thoughts that weaken you from hearing the still small voice that your not even really listen to. Judging each other is still flesh and bloods ability which needs what it needs to hear and see, Luke 17: Left a hint for how spirit is working in silence in man still blind to where God and kingdom is.
20And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation:
21Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you.
Judging Paul is milk opinions about what Paul was preaching to who and why you can't trust it, only concern for Paul was false gospels by great Men who had to dress and power laws for thinking its salvation which Paul did the same thing when Saul Romans 2:
28For he is not a Jew, which is one outwardly; neither
is that circumcision, which is outward in the flesh:
29But he
is a Jew, which is one inwardly; and circumcision
is that of the heart, in the spirit,
and not in the letter; whose praise
is not of men, but of God.
