The wise man does nothing but what can be done openly and without falseness, nor does he do anything whereby he may involve himself in any wrong-doing, even where he may escape notice. For he is guilty in his own eyes before being so in the eyes of others; and the publicity of his crime does not bring him more shame than his own consciousness of it.
Ambrose... the Lord Jesus said, 'To those who are in bonds, Come out, and to those who are in prison, Go forth' (Isa. 49:9); so your sins are forgiven. All, then, are forgiven, nor is there any one whom He has not loosed. For thus it is written, that He has forgiven 'all transgressions, doing away with the handwriting of the ordinance that was against us' (Col. 2:13-14). Why, then, do we hold the bonds of others, while we enjoy our own remission? He, who forgave all, required of all that what every one remembers to have been forgiven to himself, he also should forgive others.
