I think that you do not understand still.
The Gospel can be an extremely healing experience if you let it be. But until then, you cannot hope to give correction, because that correction, however well-intending you may make it seem, is not coming from a place of sincere concern. No, it is coming from a well-disguised place of bitterness.
Let it go.
First comes love, then comes truth. It cannot be the opposite way around, because it is easy to tell when there is no love in truth. It is called anger, and it's an excuse to be ungracious to other brothers and sisters hidden under the Christian practice of "rebuking."
Accept the grace that is given to you. Then learn to extend that grace to others.
