Neglect not the wounded and feeble, but that you may more easily make whole, whole you ought to be.
Correct by reproving, comfort by addressing, set an example by living well, He will be with them that has been with you…
Where you have come they will come; where you have passed they will pass.
grievous thing it is indeed, and exceeding perilous, nay ruinous, and for certain a deadly thing, that witting they sin.
For in one way to these vanities does he run that despises the voice of Christ;
in another way, he that knows from what he is fleeing.
But that not even of such men we ought to despair,
this Psalm
[“Have mercy on me O God according to Your great mercy”] shows.
St. Augustine, Commentary on the Psalms
