'But I have no obligation whatsoever. Moreover, our only duty is to become united to God.'

Considerations from the saints ...

Those who err in spirit shall acquire understanding,
and those who find fault shall receive instruction. - Isaiah 29:24

'We should not be concerned about such matters at all. It is true that I would be of your opinion and act perhaps in the same way had I any responsibility in the matter. But I have no obligation whatsoever. Moreover, our only duty is to become united to God. Even if we were members of those communities which are being publicly criticized for their defections, we would be greatly at fault in becoming disquieted on that account.'" - "My Sister, St. Therese" - Sr. Genevieve of the Holy Face

Therese to Celine: "You have no responsibility in the guidance of souls, so to set about instructing others, even when truth is on your side, is exposing yourself to danger unnecessarily. You are not called to be a Justice of the Peace. This right belongs to God alone." - My Sister St. Therese, by Genevieve of the Holy Face

“Do not ask God to save such and such a person, or to help this one or that, but ask him that you may love him, and that his will may be done. You must talk with him familiarly, and explain to him that you want to love him well, but that you can’t do it, that many things seem obscure and illogical to you, and that you would like to understand them a little better … and do not hesitate, all day long, to invoke heaven.” - Jacques Fesch

"I prefer you to make mistakes in kindness than to work a miracle in unkindness," Mother Teresa wrote to her sisters. This was a principle she herself followed. It was precisely this attitude of being kindly disposed that led her to look at others' actions in a favorable light, to give them the benefit of the doubt or to overlook a mistake. This kindness made her approachable and sought after even by people whose opinions were opposed to hers. Such kindness that communicates love was what she demanded of her sisters: "Be the living expression of God's kindness: kindness in your face, kindness in your eyes, kindness in your smile, kindness in your warm greeting. In the slums we are the light of God's kindness to the poor." - St. Teresa of Calcutta, Source
