John Chrysostom

"Rejoiceth not in unrighteousness:" i.e., doth not feel pleasure over those that suffer ill: and not this only, but also, what is much greater, "rejoiceth with the truth." "She feels pleasure," saith he, "with them that are well spoken of," as Paul saith, "Rejoice with them that rejoice, and weep with them that weep."

Hence, she "envieth not," hence she "is not puffed up:" since in fact she accounts the good things of others her own.

Seest thou how by degrees love makes her nursling an angel? For when he is void of anger, and pure from envy, and free from every tyrannical passion, consider that even from the nature of man he is delivered from henceforth, and hath arrived at the very serenity of angels.
