The tongue is a small member, but it does big things. A religious who does not keep silence will never attain holiness; that is, she will never become a saint. Let her not delude herself - unless it is the Spirit of God who is speaking through her, for then she must not keep silent. But, in order to hear the voice of God, one has to have silence in one's soul and to keep silence; not a gloomy silence but an interior silence; that is to say, recollection in God.
Mary Faustina KowalskaFor there are three ways of performing an act of mercy: the merciful word, by forgiving and by comforting; secondly, if you can offer no word, then pray - that too is mercy; and thirdly, deeds of mercy. And when the Last Day comes, we shall be judged from this, and on this basis we shall receive the eternal verdict.
